Sentron 3WT Circuit Breaker –The Art of Simplicity.

During the last decade, with the introduction of 3WN and3WL Circuit Breakers, Siemens introduced a new perspectivein the field of Switching technology and Intelligentcommunication. The standards of Performance, Reliability,and Safety were further raised through the Sentron series andoffered an “Art of Intelligent Simplicity”.

Siemens Sentron family of Air circuit breaker grows furtherand now offers an additional range of 3WT Circuit breakers for greater choice and optimized selection in LVpower system.

Sentron 3WT is available with Siemens hallmark of Performance, Reliability, Safety, Ease of operation andMaintenance, and accurate protections under the banner:

Sentron 3WT Circuit Breaker “The Art of Simplicity”.

3WT is available from 630 A to 3200 A in two frame sizes with thefollowing advantages:

3WT conforms following standards:

• IEC 60947 –2, IS 13947 -2

• VDE 0660 Part 101

• GB 14048.2

• Climate proof to IEC 60 068 –2-30

• Approval according to maritime classification on request.

Safety Plus:

• Interchangeable Line- Load terminals.

• Front cover can’t be removed if the circuit breaker is in closedcondition.

• “SAFE OFF” Suitable for isolation. Castell key can be removedonly when contacts are separated.

• Locking of withdrawable circuit breaker against moving, asstandard.

• Locking of the guide frame with the circuit breaker removed,as standard.

• Trip signalling switch for overload and short circuit trippingwith mechanical closing lock out.

• Distinct “Ready to Close” interlocking is provided as inherentsafety features. This ensures safe switching ON of ACB andeases the diagnosis.

• 3WT conforms to positive isolation requirement as per IEC 60-947- 2.

Easy Plus:

Ease of Operation, Maintenance and Upgradation:

• Unambiguous ON- OFF indicator with auxiliary switch forsignal.

• Click-fit front mounted accessories e.g. Shunt, Under Voltage,etc can be replaced without removing the breaker from thepanel and needs no calibrations.

• High electrical life reduces frequency of replacement ofcontacts.

• Permits last minute up-gradation. e.g converting from Manualto Motorized or from fixed to draw-out.

• Built-in test features of the release permit testing of thebreakers and trip circuitry without additional test kit.

• Contact erosion indicator for predictive maintenance.

Compact and Power Saver:

• Continuous rated low consumption accessories like shunt,Motor, Under Voltage bring down the cost and size of thecontrol transformer.

• Low power loss improves the inpanel rating of the circuitbreaker without increasing the circuit breaker width.

Simplicity of inspection and operational safety

Keyless Mechanical Interlocking

• Two or three breakers can bemechanically interlocked

• Ideal for auto change oversystems

• The breakers can be mountedside by side or above each other

Easily approachableprotection C.Ts

• Fire retardant insulatingmaterial

Contact erosion indicator

• No adjustments requiredafter replacing powercontacts

Insulating enclosure segregatesphases completely and isolatesthe power contacts from thefront accessible operatingmechanism/auxiliaries/trip unitcompartments

Front accessible secondaryisolating contacts permitinspection and retrofitting ofauxiliaries without removingthe breaker from the guideframe

Metallic guide rails hold thebreaker in maintenanceposition for inspection andretrofitting of auxiliaries

Racking window blocks accessto the racking mechanism.The window opens only whenthe ‘OFF’ push button is keptdepressed, preventing rackingof the breaker in ‘ON’condition.

Reliability Plus:Microprocessor Based Release for Ultra Accurate Protections:

Trip units The Microprocessor based releases which measures TRUE RMScurrent are provided with following standard features:

• Integrated Test Features:The test button test the healthiness of microprocessor basedtrip units, trip solenoid and breaker mechanism with orwithout tripping of the circuit breaker. This eliminates externaltest unit to check the healthiness of the protection measuringsystem.

• Active LED to show healthiness of ETU:Correct operation of the trip unit is indicated by the“heartbeat” of a green flashing LED. Rapid flashing of LED willindicate whenever load current exceeds the threshold value ofoverload protections.

• Fault Clarity and Fault History:The LEDs shows the reason for tripping of the breaker. Faulthistory is also recorded and can be recovered by QUERYbutton.

6

• Microprocessor Bypass circuit:If a microprocessor fault occur, the alarm will activate redLED “MP”. This alarm indicates that the overloadprotection functions are not currently active. However,with the internal bypass circuit, trip unit guaranteesprotection against short-circuit.

7

Comprehensive additional functions for high uptime:

Comprehensive additional functions – in accordance with thedesign of the trip unit, e.g.:

• Short time-delay short-circuit release with I2t-dependent delayfor improved discrimination to the downstream fuses

• Thermal memory

Ground-fault protection

• Description

Ground-fault releases “G” sense fault currents that flow toground and that can cause fire in the plant. Multiple circuit-breakers connected in series can have their delay timesadjusted so as to provide time-graded discrimination.

The reason for tripping is indicated by means of an LED whenthe query button is activated.

• Measurement methods

– Vectorial summation formation with current transformer inneutral conductor

The neutral conductor current is measured directly and isevaluated for neutral conductor overload protection.

The trip unit determines the ground-fault current by meansof vectorial summation of current in all three phases andthe N-conductor current.

Trip unit version Current transformer T5 must beconnected to auxiliary current connection

• ETU5WT, ETU8WT 400.13400.14

For 4-pole circuit-breakers, the fourth current transformerfor the N-conductor is installed internally.
