Communication-capable circuit breakers (with ETU45B or ETU76B electronic release)

Features• Coordinated communication concept using the PROFIBUS DP

or MODBUS, ranging from 16 A to 6300 A with SENTRON 3VL and SENTRON 3WL

• The high level of modularity of circuit breakers and accessories allows easy retrofitting of all communication components

• Significant additional benefits for the switchboard due to the possibility of linking up external input and output modules to the circuit breaker-internal CubicleBUS of the SENTRON 3WL

• Innovative software products for parameterization, operation, monitoring, and diagnostics of SENTRON circuit breakers, both locally or via PROFIBUS DP, MODBUS or Ethernet/Intranet/Internet

• Complete integration of the SENTRON circuit breakers into the Totally Integrated Power and Totally Integrated Automation solutions

Communication: • For air circuit breakers with optional communication function

(ETU45B or ETU76B electronic release) see pages 15/7 to 15/22.

• For accessories see pages 15/43 and 15/44. • For more information see also the chapter "Power Manage-

ment System" and "Software for Power Distribution".

■ Benefits

Low space requirements

The SENTRON 3WL devices require very little space. Size I de-vices (up to 1600 A) fit into a 400 mm wide switchgear panel. Size III devices (up to 6300 A) are the smallest of their kind and with their construction width of 704 mm fit into a 800 mm wide switchgear panel.

Modular design

Components like auxiliary releases, motorized operating mechanisms, electronic releases, current sensors, auxiliary cir-cuit signaling switches, automatic reset devices, interlocks and engagement operating mechanisms can all be exchanged or retrofitted at a later stage, thus allowing the circuit breaker to be adapted to new, changing requirements.

The main contact elements can all be replaced in order to in-crease the endurance of the circuit breaker.

Retrofittable modules for electronic releases

Modularity is one of the main features of the new SENTRON 3WL circuit breakers. Special LCDs, ground-fault modules, rated current modules and communication modules for the electronic releases are available for fast and easy retrofitting and adaptation to changing requirements.

Communication

The use of modern communication-capable circuit breakers opens up completely new possibilities in terms of start-up, parameterization, diagnostics, maintenance and operation. This allows many different ways of reducing costs and improving pro-ductivity in industrial plants, buildings and infrastructure projects to be achieved.

• Fast and reliable parameterization• Timely information and response can prevent plant

stoppages• Effective diagnostics management• Measured values are the basis for efficient load management,

for drawing up power demand profiles and for assigning en-ergy to cost centers

• Preventive maintenance reduces the risk of expansive plant down-times

■ Application • As incoming-feeder, distribution, tie, and outgoing-feeder cir-

cuit breakers in electrical installations• For switching and protecting motors, capacitors, generators,

transformers, busbars and cables

Due to the reinforced use of electronic I&C systems, the de-mands made on air circuit breakers in terms of operator control and monitoring of network processes have increased.

The extensive, coordinated SENTRON range of devices covers all applications between 16 A and 6300 A with compact and air circuit breakers.

The AC devices are available as circuit breakers and non-auto-matic air circuit breakers. DC devices are only available as non-automatic air circuit breakers.

Standards

SENTRON 3WL circuit breakers comply with:• IEC 60947-1, EN 60947-1• IEC 60947-2, EN 60947-2• Climate-proof according to IEC 60068-2-30.

Versions with UL 489 also available, see Catalog LV 16.

For further standards, see Appendix.

Footnotes for pages 15/7 to 15/10:1) The rated current is determined by the rated current module. For the stan-

dard version, the supplied module is equal to the maximum rated current. If a lower rated current is required, adaptation by order code on page 15/24.

2) For permissible rated short-time current Icc and rated short-circuit making capacity Icm for non-automatic air circuit breakers see Technical Informa-tion LV 1T, "Technical specifications".

3) Current transformers for protection of the N conductor and current trans-formers for detection of the ground-fault current in the grounded neutral point of the transformer are to be ordered separately, see page 15/34.

4) Current transformers for protection of the N conductor are to be ordered separately, see page 15/34.

5) ETU45B and ETU76B with ground-fault protection module GFM AT (alarm and tripping), see page 15/34.

1) For replacement in existing circuit breakers please specify the circuit breaker ID No. when ordering.

2) With the rated current module selected, the maximum rated current In max of the circuit breaker must not be exceeded. The following applies In � In max.

3) For direct measurement of the ground-fault current, e.g. in the neutral point of the transformer, a 1200 A/1 A current transformer, class 1, is required. The internal load of the SENTRON 3WL is 0.11 m. If the ground-fault cur-rent is to be determined using the vectorial sum of the phases, a current transformer must be installed in the neutral conductor.

3WL1ÔÔÒ–ÖéâÕÓ–ÓáÜÔ An important prerequisite for computer-based order processing is that order numbers must be structured according to standardized criteria.

They are used as an unambiguous means of communication for various purposes:

• Offer processing Selection and configuration

• Order processingOrdering Order confirmationHandling warehouse products Order processing at the supply bases Delivery and shipment

• Reporting and planning

• Service and warranty

The standardized structure ensures that only one Order No. has to be adminis-tered for one device.

This saves time and effort during planning, configuring, ordering and stock keeping, and consequently above all it saves costs.

The example opposite explains the various positions within an Order No.

■ Design

Overview of SENTRON 3WL circuit breakers/non-automatic air circuit breakers

Versions

• Rated currents: 630 A to 6300 A• 3 sizes for different rated current ranges (see illustration

"Overview of SENTRON 3WL Circuit Breakers/Non-Automatic Circuit Breakers")

• 3- and 4-pole versions• Rated operational voltage up to 690 V AC and 1000 V DC.

Special versions up to 1000 V AC and 1150 V AC available• 4 different switching capacity classes in the range from 55 kA

to 150 kA for AC applications and one switching capacity class for DC applications.

The SENTRON 3WL circuit breakers are supplied complete with operating mechanism (manual operating mechanism with me-chanical closing), solid-state release and auxiliary switches (2 NO contacts + 2 NC contacts in the standard version), and can be equipped with auxiliary releases.

Installation types

Fixed-mounted or withdrawable version

Ambient temperaturesThe SENTRON 3WL circuit breakers are climate-proof according to IEC 60068-2-30. They are intended for use in enclosed areas where no severe operating conditions (e. g. dust, corrosive va-pors, damaging gases) are present.When installed in dusty and damp areas, suitable enclosures must be provided.

Coordinated dimensionsThe dimensions of SENTRON 3WL circuit breakers only differ in terms of the width of the device which depends on the number of poles and the size.Due to the nature of the design, the dimensions of devices with a withdrawable version are determined by the dimensions of the guide frames, which are slightly larger.

Non-automatic air circuit breakersA special version of circuit breaker is utilized as a non-automatic air circuit breaker. The non-automatic air circuit breakers are de-signed without an solid-state release system and do not perform any protection duties for the system.One potential application is the use as a bus coupler in systems with parallel feed-ins.The versions and features can be selected according to those of the circuit breakers.

Operating mechanismsThe circuit breakers are available with various optional operating mechanisms:• Manual operating mechanism with mechanical closing (stan-

dard design)• Manual operating mechanism with mechanical and electrical

closing• Motorized operating mechanism with mechanical and electri-

cal closing

The operating mechanisms with electrical closing can be used for synchronization tasks.

Main circuit connections – connection types

Main circuit connections

All circuit breakers are equipped with horizontal main circuit connections on the rear for up to 5000 A as standard (horizontal connection to busbars). Exception: Circuit breakers of size II with max. rated current 4000 A. Circuit breakers with a max. rated current of 6300 A and circuit breakers size II with a max. rated current of 4000 A are equipped with vertical main connections (for upright busbars).

The following options are available, with all combinations of top and bottom connections possible:• Accessible from the front, single hole (for vertically installed

busbars)• Accessible from the front, double hole (holes according to

DIN 43673) (for vertically installed busbars)• At the rear, vertical (for vertically installed busbars)• Connecting flange (for direct connection to guide frame up to

4000 A).

Connection options for auxiliary circuit connections

Auxiliary circuit connections

The type of connection for the auxiliary switches depends on the type of installation:• Withdrawable version: The internal auxiliary switches are con-

nected to the male connector on the switch side. When fully in-serted, the connector makes a connection with the sliding contact module (see "Design", graphic "Guide Frame") in the guide frame. Various adapters can then be used to complete the wiring (see the graphic "Connection Options for Auxiliary Circuit Connections").

• Fixed mounting: In this case the auxiliary supply connectors are engaged directly onto the circuit breaker. The connectors are equipped with coding pins that prevent them being mistak-enly interchanged.

Operator panel

The operator panel is designed to protrude from a cut-out in the door providing access to all control elements and displays with the control cabinet door closed. The operator panels for all circuit breakers (fixed-mounted/with-drawable versions, 3-/4-pole) are identical. The operator panel ensures degree of protection IP41.

Safety and reliability

To protect the circuit breakers and plant against unauthorized switching as well as the maintenance and operator personnel, the system contains many locking devices. Others can be retrofitted.

Other safety features include:• Infeed from above or below, as required• Locking of the guide frame with the circuit breaker removed,

as standard• Locking of the withdrawable circuit breaker against move-

ment, as standard• High degree of protection with cover IP55• Mechanical reclosing lockout after overload or short-circuit

release as standard• The circuit breaker is always equipped with the required num-

ber of auxiliary supply connectors

Standard version

SENTRON 3WL circuit breakers are equipped with the following features as standard:• Mechanical ON and OFF pushbutton• Manual operating mechanism with mechanical closing• Switch position indicator• Ready-to-close indicator• Memory status indicator• Auxiliary switch 2 NO + 2 NC• Rear horizontal main circuit connections for fixed-mounted and

withdrawable versions up to 5000 A, and rear vertical main cir-cuit connections for 6300 A applications and size II with 4000 A

• For 4-pole circuit breakers, the fourth pole (N) is installed on the left and is 100 % loadable with the rated current

• Contact erosion indicator for the main contacts• Auxiliary circuit plug-in system with SIGUT screw terminals

Delivery inclusive of all auxiliary circuit connectors to internal features including coding device for the prevention of incor-rect installation of auxiliary supply connectors for fixed-mounted circuit breakers

• Mechanical "tripped" indicator for solid-state release system• Mechanical reclosing lockout after tripping operation• Operator panel cannot be taken off with the circuit breaker in

the ON positionAdditional features of the withdrawable version:• Main contacts:

Laminated receptacles in the guide frame, penetration blades on the withdrawable circuit breaker

• Position indicator in the operator panel of the withdrawable circuit breaker

• Captive manual crank handle for moving the withdrawable circuit breaker

• Guide frame with guide rails for easy moving of the withdraw-able circuit breaker

• The withdrawable circuit breaker can be locked to prevent it being pushed out of position

• The withdrawable circuit breaker cannot be moved when it is in the ON position

• Coding of the rated current between the guide frame and the withdrawable circuit breaker

Withdrawable short-circuit, grounding, and bridging units

Portable positively-driven grounding and short-circuit devices are used for the disconnected system sections to verify isolation from the supply at the workplace.

Withdrawable grounding units allow simple and comfortable grounding. They are simply inserted into the guide frames in place of the corresponding withdrawable circuit breakers. This ensures that these devices are always first connected with the grounding electrode and then with the components to be grounded.

The grounding terminals are fitted to the side of the switch enclo-sure and establish the connection when inserted into the guide frame.

All withdrawable terminals are short-circuited and grounded on delivery.

Qualified electricians can easily convert it to a withdrawable bridging unit by following the enclosed instructions.

In addition, the withdrawable unit can be adapted to various rated currents of a size.

Withdrawable short-circuit and grounding unit

The withdrawable short-circuit and grounding unit consists of a breaker enclosure with penetration blades which are connected with the short-circuiting link.

Depending on the version, the short-circuiting links are arranged at the top or bottom. The grounding and short-circuit connec-tions are established when the device is inserted.

It must be ensured that the side to be short-circuited and grounded is not live. For this reason it is recommended that the withdrawable unit is only wound in when the door is closed.

Withdrawable bridging unit

The withdrawable bridging unit consists of a breaker enclosure in which all disconnection components and the operating mech-anism have been replaced with simple connections between the upper and lower contacts.

Auxiliary releases

Up to two auxiliary releases can be installed at the same time. The following are available:

1 shunt release or 1 undervoltage release or 2 shunt releases or 1 shunt release + 1 undervoltage release

Signal switch for auxiliary releases

One signaling contact is used for each auxiliary release to deter-mine the positions of the auxiliary releases.

Shunt releases

When the operational voltage is connected to the shunt release, the circuit breaker is opened immediately. The shunt release is available in the versions 5 % ON period for overexcitation and 100 % ON period for permanent excitation. This means that it is also possible to block the circuit breaker against being jogged into closing.

An energy storage device for shunt releases allows the circuit breaker to be opened even if the control voltage is no longer available.

Undervoltage releases

The undervoltage release causes the circuit breaker to be opened if the operational voltage falls below a certain value or is not applied. The circuit breaker cannot be closed manually or by means of an electrical ON command if the undervoltage release is not connected to the operational voltage. The undervoltage re-lease has no delay as standard. A delay can be set by the cus-tomer in the range between td < 80 ms and td < 200 ms.

In addition, an undervoltage release with a delay in the range from 0.2 to 3.2 s is available.

Closing solenoid

The closing solenoid is used to close the circuit breaker electri-cally by means of a local electrical ON command or by a remote unit.

Motorized operating mechanisms

The operating mechanism is used to load the storage spring au-tomatically.

The operating mechanism is activated if the storage spring has been unloaded and the control voltage is available.

It is switched off automatically after loading. This does not affect manual operation of the storage spring.

Indicators, signals, and control elements

Motor shutdown switch

Control switch for switching off the motorized operating mecha-nism (automatic loading).

Operating cycles counter

The motorized operating mechanism can be supplied with a 5-digit operating cycles counter. The display is incremented by "1" as soon as the storage spring is fully loaded.

Resetting the manual tripped signal

When the circuit breaker has tripped, this is indicated by the pro-truding red mechanical tripped indicator on the ETU. When the mechanical tripped indicator is activated, the tripping solenoid and tripped signal are reset. If this display is to be reset remotely, the reset button can be equipped with a reset solenoid.

This option allows the circuit breaker to be reset both manually and electrically.

Automatic resetting of reclosing lockout

When the ETU is activated, reclosing of the circuit breaker is pre-vented until the release is either electrically or manually reset. If the "Automatic resetting of reclosing lockout" option is used, the pre-tensioned circuit breaker is ready to close immediately after tripping. Resetting the manual tripped indicator is not included in this option.

Tripped signal switch

If the circuit breaker has tripped due to an overload, short-cir-cuit, ground fault or extended protection function, the tripped signal switch can indicate this. This signal switch is available as an option. If the circuit breaker is used for communication, this option is supplied as standard.

Ready-to-close indicator switch

The SENTRON 3WL circuit breakers are equipped with an opti-cal ready-to-close indicator as standard. In addition, the ready-to-close status can be transmitted by means of a signal switch as an option. If the switch is used for communication, the signal switch is supplied as standard.

Locking devices

Locking device in OFF position

This function prevents closing of the circuit breaker and com-plies to the specifications for main switches to EN 60204 (VDE 0113) - disconnector unit. This lockout only affects this cir-cuit breaker.

If the circuit breaker is replaced, closing is no longer prevented unless the new circuit breaker is also protected against unautho-rized closing.

To activate the locking device, the circuit breaker must be opened. The locking device is disabled when the circuit breaker is closed. The lock is only activated when the key is removed. The safety key can be removed only in the "OFF" position.

Locking device for "Electrical ON" (see graphic "Circuit breakers")

This prevents unauthorized electrical closing from the operator panel. Mechanical closing and remote closing remain possible. The lock is only activated when the key is removed.

Locking device for "Mechanical ON" (see graphic "Circuit breakers")

This prevents unauthorized mechanical closing. The mechanical ON button can only be activated if the key is inserted (key oper-ation). Closing with the "Electrical ON" button and remote closing remain possible. The lock is only activated when the key is removed.

"Secure OFF" circuit breaker-independent locking device against unauthorized closing

This special switch-independent function for withdrawable cir-cuit breakers prevents closing and fulfills the specifications for main switches to EN 60204 (VDE 0113) – disconnector unit. Un-authorized closing remains impossible even after the circuit breaker has been exchanged.

To activate the lock, the circuit breaker must be opened. The locking device is disabled when the circuit breaker is closed. The lock is only activated when the key is removed. The safety key can be removed only in the "OFF" position.

Locking device for crank handle

Prevents removal of the crank. The circuit breaker is protected against movement. The lock is only activated when the key is removed.

Locking device for "Mechanical OFF"

Solid-state releases (ETU)

The solid-state release is controlled by a microprocessor and operates independently of an auxiliary voltage. It enables sys-tems to be adapted to the different protection requirements of distribution systems, motors, transformers and generators.

Communication capabilities

The international standard PROFIBUS DP or MODBUS can be used to transmit data such as current values, switching states, reasons for tripping etc. to central computers.

Data acquisition and energy management are possible in con-junction with the Plus measurement function.

A new internal circuit breaker data bus allows switchboard panel communication between the circuit breaker and secondary de-vices in the circuit breaker section:• Actuation of analog displays• Facility to test the communication build-up with circuit

breakers• Display of tripping state and tripping reasons• Input module for reading in further switchgear panel signals

and for transmission of these signals to the PROFIBUS DP or MODBUS

• Various output modules for displaying measured values

This means that it is not only possible to monitor the device re-motely, but also to transmit current values from the entire system and perform switching operations remotely.

I2t and I4t characteristic curve for overload protection

The best protection for the whole switchgear is achieved by set-ting the tripping characteristic curve to an optimum value. In or-der to achieve optimal discrimination for upstream fuses or me-dium voltage protection systems, the inclination of the characteristic curve can be selected for the overload range.

The overload protection L (long time protection) for the solid-state releases ETU45B and ETU76B allows the characteristic curve to be switched between I2t and I4t.

The I4t characteristic improves discrimination for downstream circuit breakers and fuses.

Solid-state releases ETU

Modularity has also been strictly emphasized during the devel-opment of the solid-state releases. These are some of the modules which can be easily retrofitted at any time:• Ground-fault protection module • Communication • Measurement function • Display • Rated current module (Rating Plug)

This allows quick adaptation to new local mains specifications. In addition, innovative functions have been included in the ETUs.

Rated current module/Rating Plug

The rated current module is an exchangeable module which al-lows the user to reduce the rated device current so as to adapt it optimally to the plant; e. g. if a new plant section is taken into operation. The rated current module must be selected to fit the rated current of the plant.

Example of configuration for ETU45B

Measurement function Plus

Selectable parameters

In the case of quick changes of power supply conditions, e. g. for switchovers from transformer to generator operation or if a section of the supply is disconnected when the shift changes, SENTRON 3WL allows the relevant protection param-eters to be quickly adapted to the new conditions. The ETUs contain two independent tripping characteristic curves (parameter sets). The switchover is completed within 200 ms and is performed with the help of an external signal.

Measurement method

Vectorial summation current formation (measurement method 1)

The three phase currents and the N conductor current are mea-sured directly.

The solid-state release determines the ground-fault current by means of vectorial summation current formation for the three phase currents and the N conductor current.

Direct measurement of the ground-fault current (measurement method 2)

A standard current transformer with the following data is used for measurement of the ground-fault current: 1200 A/1 A, Class 1 (the internal load of SENTRON 3WL is 0.11 �). The current trans-former can be installed directly in the grounded neutral point of a transformer.

3-pole circuit breakers, current transformers in the N conductor

3-pole circuit breakers, current transformers in the grounded neutral point of the transformer

4-pole circuit breakers, current transformers in the grounded neutral point of the transformer

Setting

How the module is set depends on the measurement method used (see above):

Measurement method 1: in position .

Measurement method 2: in position .

This setting can be implemented for the solid-state release ver-sion ETU76B with Menu/Comm.

Ground-fault protection with I2t characteristic curve

With the exception of the ETU27B solid-state release, all versions of the ground-fault modules are supplied with an I2t characteristic curve which can be activated.

Selection criteria for SENTRON 3WL circuit breakers

Basic criteria for selecting circuit breakers are:• Max. short-circuit current at place of installation of circuit

breaker I �k max. This value determines the short-circuit breaking capacity or short-circuit current carrying capacity of the circuit breaker.

• It is compared with the value Icu, Ics, Icw of the circuit breaker and essentially determines the size of the circuit breaker. See illustration "Overview of SENTRON 3WL Circuit Breakers/Non-Automatic Air Circuit Breakers".

• Rated current In which is to flow through the branch circuit. This value must not be larger than the maximum rated current for the circuit breaker.The rated current for the SENTRON 3WL is set with the rated current module. See "Design", illustration "Overview of SENTRON 3WL Circuit Breakers/Non-Automatic Air Circuit Breakers".

• Ambient temperature for the circuit breaker. This is usually the control cabinet internal temperature.

• Design of the circuit breaker• Minimum short-circuit current

which flows through the switching device. The release must still detect this value as a short-circuit and must respond by tripping.

Protection functions of the circuit breaker. These are determined by the selection of the corresponding solid-state release, see the table "Functions of the solid-state releases" under "Functions".

SENTRON 3WL for DC applications

This version of the 3WL non-automatic air circuit breaker is suit-able for direct current applications. The external protective de-vice DIGmat S100 provides adjustable overload and short-circuit protection for the SENTRON 3WL non-automatic air circuit breaker.

This is based on the measuring chain of a shunt resistor and the DIGmat S100 tripping unit. Shunt resistors are available for 1000 A, 2000 A and 4000 A (special ranges on request). They are in accordance with DIN 43703 and have a class accuracy of 0.5.

A measuring-circuit voltage of 60 mV DC is picked off for rated current In.

The measuring-circuit voltage is a linear image of the primary current.

The DIGmat S100 tripping unit monitors the image of the primary current thus supplied and compares it with the tripping charac-teristic curve set on the device. The parameter settings on the DIGmat S100 apply also for DC feedbacks. Reversing duty is possible therefore.

The tripping characteristic curve is determined and described by the following variables:• Overload protection:

Setting range IR = 0.4 ... 1.0 InThe curve has a I2t characteristic.The tripping time tR is selectable between 2 and 10 s, with tR defined for 6 × IR.

DIGmat S100

• Short-circuit protection:Setting range Ii = 1.25 × IR up to max. 4 × In If the set value is exceeded, tripping occurs in less than 50 ms.

In = Rated current of the circuit breakerIR = Set current value of the adjustable overload releasetR = Assigned tripping time of the overload tripIi = Instantaneous tripping current of the adjustable short-

circuit releases

The components are available only from the company mat – Maschinen- und Anlagentechnik (for address see "Appendix" => "External Partners").

■ Configuration

Mutual mechanical circuit breaker interlocking

The module for mutual mechanical interlocking can be used for one or two SENTRON 3WL circuit breakers and can be adapted easily to the corresponding versions. The fixed-mounted and withdrawable circuit breaker versions are fully compatible and can therefore be used in a mixed configuration in an installation. This also applies to 3WN6 circuit breakers.

The circuit breakers can be mounted alongside each other or one above the other, whereby the distance of the circuit breakers is determined solely by the length of the Bowden wire (lengths: 2 m/3 m/4.5 m). Interlock signals are looped through using the Bowden wires. Interlocking is only effective in the connected po-sition in the case of withdrawable circuit breakers. The mechan-ical endurance of the Bowden cables is 10 000 operating cycles.

Minimum requirements must be fulfilled in the switchgear for the interlocking to function:• Bowden wires must be installed as far as possible in a straight

line with minimum bending.

• The bending radii of the Bowden wire must be greater than 500 mm.

• The sum of all bending angles along the Bowden wire must not exceed 640°.

• In a vertical arrangement of circuit breakers to be interlocked, the interlocking mechanisms must be in line.

• Circuit breakers to be interlocked must be arranged so that Bowden cables can be optimally installed in compliance with the conditions mentioned in the above points.

• The installed Bowden wire must be fixed (with cable ties or the like) before the interlock is adjusted.

• Select the width of switchgear cubicle to allow enough free-dom of movement for adjusting the interlock!

• Openings and cut-outs in system elements must be designed so that Bowden wires are not changed in direction or ob-structed when they are passed through.

Communication-capable circuit breakers

Communication with PROFIBUS DP

Communication with MODBUS

The requirements for power distribution in terms of communica-tion capability, data transparency, flexibility and integration are constantly increasing. An integrated and modular communica-tion architecture was designed for the SENTRON 3WL to ensure that it can satisfy these requirements.

The core component of this architecture is the CubicleBUS, which links together all of the intelligent components within the SENTRON 3WL and enables the easy and safe connection of other additional external components to the circuit breaker. The CubicleBUS is already incorporated and pre-connected in all complete circuit breakers with ETU45B and ETU76B releases.

The high level of modularity of the system allows communication functions to be retrofitted at any time (e. g. the measurement function). Similarly, the upgrade of a non-communication-capa-ble SENTRON 3WL (e .g. changeover from ETU25B to ETU45B with CubicleBUS) can be carried out easily on site in the plant. All modules connected to the CubicleBUS can directly access the existing source data of the circuit breaker, which guarantees the quickest possible access to information and response to events.

Furthermore, additional external modules (including digital in-puts/outputs, analog outputs) can be connected to the CubicleBUS to provide cost-effective solutions for the automa-tion of further devices in the switchgear.

CubicleBUS modules

Digital output modules with rotary coding switch

6 items of binary information concerning the state of the circuit breaker (reasons for tripping and warnings) can be output via this module to external signaling devices (e. g. LED, horn) or be used for the selective shut-down of other system components (e. g. frequency converters).

Digital output modules are available in versions with and without a rotary coding switch. On modules with a rotary coding switch it is possible to choose between two signaling blocks each with 6 defined assignments and to set an additional response delay.

All the digital output modules are available as a version with re-lay outputs (CO contacts, up to 12 A). Up to two modules of this type can be connected to one SENTRON 3WL.

Digital output module with rotary coding switch

Digital output modules, configurable

The configurable output module is available for higher-perfor-mance solutions. With this module, random events on the CubicleBUS can be switched directly to one of six available out-puts or three of these outputs can be assigned with up to six events. In other words, up to six events can be placed on one physical output with OR operation. Either BDA/BDA Plus or Switch ES Power is used for configuring.

A relay variant is also available here the same as for the output modules with rotary coding switch. Only one module of this type is possible per SENTRON 3WL.

Digital output module, configurable

Analog output modules

The analog output module can be used to output the following measured values to analog indicators in the control cabinet door:• IL1, IL2, IL3, IN or• UL12, UL23, UL31, UL1N or• PL1, PL2, PL3, Stot or• p.f.1 , p.f.2 , p.f.3, �I % or• favg, ULLavg, Ptot, p.f.avg

Four 4-20-mA/0-10-V interfaces are available for this. The mea-sured values to be output are selected with a rotary coding switch. By using the analog output module it is possible to do without additional converters and their conventional installa-tion/wiring in the main current path. Up to two modules of this type can be connected to one SENTRON 3WL.

Analog output module

Digital input modules

With the digital input module, up to 6 additional binary signals (24 V DC) in the circuit breaker environment can be connected to the system. It is thus possible for example to send messages concerning the state of a switch disconnector or a control cabi-net door to the PROFIBUS DP/MODBUS.

With the digital input module on the CubicleBUS it is also possi-ble for the two different protection parameter sets held in the ETU76B solid-state releases to be switched over automatically in a few milliseconds. It is thus possible, for example, to automati-cally change the parameters of a coupling switch should the transformer infeed fail.

One module each of this type can be used for holding the six items of digital information and for automatically switching over the parameters.

Digital input module

ZSI modules (short-time grading control)

The use of ZSI modules is recommended when Siemens circuit breakers are arranged in several staggered levels but full grad-ing with the smallest possible delay is to be assured nevertheless.

The circuit breakers are interconnected by these modules. In case of a short-circuit, each affected circuit breaker asks the cir-cuit breakers directly downstream whether the short-circuit has also occurred in the next, lower level. The short-circuit is exactly localized as the result, and only the next upstream circuit breaker in the energy flow direction is switched off.

■ Characteristic curves

Every solid-state release type and every setting has its own characteristic curve. Only a selection is shown in the following. The characteristic curves each show the largest and smallest setting range of SENTRON 3WL circuit breakers with 1000 A rated current at 500 V rated voltage with various releases. In or-der to obtain a complete tripping characteristic, the relevant parts of the characteristics have to be combined.The characteristic curves show the behavior of the solid-state re-lease when it is activated by a current that is already flowing be-fore the tripping operation. If the overcurrent tripping occurs im-mediately after switch on and the solid-state release is therefore not yet enabled, the opening time is extended, depending on the level of the overcurrent by up to 15 ms. In order to determine the break-times of the circuit breakers, approximately 15 ms must be added to the opening times shown for the arcing time.2)

Refer to the following legend for tolerances.The characteristic curves shown apply to ambient temperatures at the circuit breaker between –5 and +55 °C. The release can be operated at ambient temperatures of –20 to +70 °C. An ex-tended tolerance band can apply at these temperatures.

times of the short-circuit release can be extended by approx. 10 % and the tripping times by approx. 15 % compared to the characteristic curve.

Every solid-state release type and every setting has its own characteristic curve. Only a selection is shown in the following. The characteristic curves each show the largest and smallest setting range of SENTRON 3WL circuit breakers with 1000 A rated current at 500 V rated voltage with various releases. In or-der to obtain a complete tripping characteristic, the relevant parts of the characteristics have to be combined.The characteristic curves show the behavior of the solid-state re-lease when it is activated by a current that is already flowing be-fore the tripping operation. If the overcurrent tripping occurs im-mediately after switch on and the solid-state release is therefore not yet enabled, the opening ime is extended, depending on the level of the overcurrent by up to 15 ms. In order to determine the break-times of the circuit breakers, approximately 15 ms must be added to the opening times shown for the arcing time.2)

Refer to the following table for tolerances.The characteristic curves shown apply to ambient temperatures at the circuit breaker between -5 and +55 °C. The release can be operated at ambient temperatures of -20 to +70 °C (ETU76B with graphics display up to +55 °C). An extended tolerance band can apply at these temperatures.

Further characteristic curves are shown in the manual and the planning and configuring tool SIMARIS deSign, or ask your Siemens contact person.

Tolerances for the set currents L: tripping operations between 1.05 and 1.2 × IRS: –0 %, +20 %I: –0 %, +20 %G: –0 %, +20 %

Tolerances for the tripping times L: –20 %, +0 % for I2t characteristic curveS: –0 %, +60 ms or -0 %, 10 % for tripping times greater than 600 ms I: < 50 ms G: –0 %, +60 ms or -0 %, 10 % for tripping times greater than 600 ms

1) Sizes I and II: 100 ... 1200 A Size III: 400 ... 1200 A.

2) With single-pole loading in the lowest rated current range, the response times of the short-circuit release can be extended by approx. 10 % and the tripping times by approx. 15 % compared to the characteristic curve.

■ Schematics

Schematics of the DIGmat S100 and the SENTRON 3WL non-automatic air circuit breaker

Application examples

The connection to the circuit breakers is not dependent on direc-tion and polarity; the circuit diagrams can be adapted accordingly.If the parallel or series connections are made directly to theconnecting bars, for thermal reasons the continuous load on the circuit breakers must only be 80 % of the permissible operational

current. If the parallel or series connection is made at a distance of 1 m from the connecting bars, the circuit breaker can be used at full operational current load.
