PANELS MECHANICAL CONSTRUCTION (GENERAL) The basic mechanical design comprises the frame, the outer sheathing and interior partitions. The basic elements of the frames are C-sections of 2 mm thick sheet steel with holes at 25 mm intervals. The parts of the framework are secured with self-tapping screws and require no maintenance. The open design is equipped with a protective rod on the front side. Panels with degree of protection of IP 31/41 can be equipped with ventilation grids. The cubicle construction up to degree of protection IP 54 is covered. The windows in the doors are made of layer bonded glass. Panel doors, if any, as well as roof and floor plates are made of 2 mm sheet steel; the vented roof plates. The doors of modules, the side and rear walls are of 1,5 mm sheet steel. Module and panel doors are equipped with a 5 mm double bit lock. All single door executions are normally hinged at the left hand side. Only the hinges of the cable compartment doors are normally on the right hand side. The panels are divided into functional compartments: the equipment compartment, the busbar compartment and the cable compartment depending on the requirements or design. The equipment modules are situated in the equipment compartment, the busbar compartment contains busbars and distribution bars. The cable compartment accommo-dates the incoming and outgoing cables together with the appropriate accessories required for interconnecting the modules (cable clamps, cable connectors, wiring ducts, etc.). The equipment modules, equipment sections and cubicles are separated by barriers if required. Cubicles can be arranged for operation from one or both sides. SURFACE PROTECTION All frames parts and construction elements for internal separation are galvanized. Side plates, doors and front covers are protected by means of paint in layers.

FOUNDATION The erection of the switch gear having cable entries at the bottom requires a foundation with an opening or a cable duct. The switch gear can either be mounted on concrete floors or on foundation frames of steel sections. The area on which the switch gear is to be erected must be level. BUSBAR SYSTEMS MAIN BUSBARS The main busbars are arranged in the rear section (busbar compartment) horizontally in two selectable levels. Double busbar systems are located at the upper and lower level. While single-busbar systems are arranged either at the upper or lower level, as required. The busbars of both levels can be of the same or different scroll section. Separate, parallel or coupled operation is possible. The busbars are divided into sections corresponding to the sizes of the switch gear transport units. Units having busbars of different cross-sections can be coupled together. PANEL DISTRIBUTOR BUSBARS The panel distributor busbars are vertically arranged in the borderline between busbar and equipment compartment of a panel. For each phase is one busbar with a rectangular or angular cross section mounted. The cubicle distributor busbars (angular shape 50x30x5 mm) are embedded in a multi function separator made of insulating material and held in place by distributor bar covers guaranteeing a degree of protection of IP 20. These busbars can be arranged over the total cubicle height of the panel or installed in sections. A panel with a 600 mm equipment compartment can be fitted with two panel distributor busbar systems (basic and additional system). The connections of the modules (fixed modules and withdrawable modules) are made by means of plug-in connection. The distributor busbars are made from copper plated aluminum (Cu/A1) or copper (Cu). In each case galvanic tined. CONNECTIONS BETWEEN MODULES AND DISTRIBUTORS BUSBARS Plug-in contact blocks provide an electrical connection between modules and the distributor bars.

CABLE CONNECTIONS CABLE CONNECTION IN PANELS WITH CABLE COMPARTMENT The power and control cables are attached to the cable mounting rails in the cable compartment, positioned below the terminals of each module and led to the connecting terminals, connecting bards or cable connectors (withdrawable module technique). Control cables are connected by double terminal blocks specially developed for the MNS-System, which are suitable for the use with screw connectors, flatpin connectors and a combination with contact pins for multiple connectors. On a cable connector it is possible to connect two cables per phase. If more than two cables have to be connected an additional cable connector with copper bars must be mounted. This possibility is only included in the price quoted, if mentioned explicitly. Cable shrouds can be fitted on the cable connectors. The cable can enter either from above or below. CABLE CONNECTIONS IN CONTROL PANELS AND WIRING BETWEEN TRANSPORT UNITS The control cables are installed at the side of the panel and led to the control modules through the vertical wiring channel. Control cables and conductors for the panel-to-panel wiring are led through cable channel situated in the upper part of the equipment and cable compartment DIRECT CONNECTION TO THE CIRCUIT BREAKERS For circuit breaker installed in panels having no separate cable compartment the cable is connected direct to the parallel switch arrangement (up to 18 parallel cables) or to the cable terminal set (up to 12 parallel cables) depending on the rated current of the circuit breaker. The control cables are led at the side of the panels and are connected directly to the control terminals of the circuit breaker modules: or if required, to the terminal strips in the control equipment recess.

WITHDRAWABLE MODULE TECHNIQUE GENERAL The withdrawable module technique MNS from ABB is based upon E = 25 mm grid system like the entire mechanical construction. The grid dimension of the withdrawable module system is 8 E = 200 mm. The draw-out units consist of the withdrawable module and the frame mounted compartments. They are standardised for the sizes 8E/4, 8E/2, 4E, 8E, 16E and 24E. For the size 8E/4 there are four modules, for the size 8E/2 two modules in a horizontal arrangement at a width of 600 mm. Modules size 4E, 8E, 16E and 24E require each the total equipment compartment width of 600 mm. Empty spaces for the area for the control cable duct at the cubicle top an the area for the PE busbar at the cubicle bottom are provided with hinged sheet metal covers. COMPARTMENTS SIZE 8E/4 AND 8E/2 Compartments size 8E/4 and 8E/2, consist of compartment bottom plate, module condaptor, guide rails and front posts. The module condaptor is the connecting link between Distributors bars, busbar system and draw-out modules and between draw-out modules and outgoing cables and wires. The connection between incoming and outgoing sides are arranged inside the draw-out module condaptor. Electrical connections are of the plug-and-socket type. COMPARTMENTS SIZE 4E ... 24E Compartments size 4E ... 24E consist of compartment bottom plate, guide rails and a sheet metal side wall with the outgoing control connector. The draw-out module feeder connection with the busbars is made by means of the module-mounted contacting unit. The outgoing power cables are connected via cable connectors (main circuit); control cable connections (auxiliary circuit) are established via terminal blocks. The power cable connectors are fastened to the multi function separator. COMPARTMENTS SIZE 8E/4 AND 8E/2 Withdrawable units size 8E/4 and 8E/2 comprise one or two profile sections for mounting Snap-On components, the rear wall with integrated cable connections and a 20-pole control connector, a front panel and two side panels. The front panel is made of insulating material with performed knockout for mounting, measuring, operating and indicating instruments. The operating handle for certain standard load-break switches and circuit breakers is also used for the electrical as well as the mechanical interlocking function. A micro switch with 2 NO and 2 NC contact is provided for electrical interlocking.

DESCRIPTION OF OPERATING HANDLE POSITIONS ON-position Operating position, main switch ON, withdrawable unit locked in position. OFF-position Main switch OFF, control circuit interrupted, withdrawable unit locked in position. TEST-position Test position, main switch OFF, control circuit closed, withdrawable unit locked in position. MOVE-position Move position, main and control circuits interrupted, withdrawable unit can be moved. ISOLATION-position Disconnected position, unit withdrawn for 30 mm and locked in position, main and control circuits interrupted. Withdrawable module mechanically interlocked. The switch handle can be moved from position OFF to position ON only after the handle has been depressed (push-to-turn feature). The switch handle can be locked in any position with up to three padlocks. The withdrawal of the unit can be prevented by an additional mechanical lock to be installed in the front cover. WITHDRAWABLE UNITS SIZE 4E ... 24E Withdrawable units size 4E up to size 24E are built-up of sheet steel components which constitute the supporting frame for the electrical components and the contact elements. The hinged front cover offers the advantage of easy accessibility to the built-in components from the front side. Opening the front cover in operation or test position of the withdrawable unit is possible only with a tool (unlatches) while in the disconnected position unlatching is possible by hand. The front cover is provided with a cut-out for a unit frame-mounted panel made of insulation material. This panel remains in position when the front cover is opened. It is designed with performed cut-outs for mounting, measuring, operating and indicating instruments and carries a switch handle by which the electrical and mechanical interlocks can be operated. A micro switch with 2 NO and 2 NC contacts is provided for the electrical interlocks. The switch handle is blocked when the main switch is closed, i.e. withdrawal of the module under load is not possible. The switch handle can be locked in any position with up to three padlocks. Withdrawal of the unit can be prevented by an additional mechanical lock to be installed in the front cover.

Multi Function Separator, Metallic Badge (MFS) The widrawable design could introduce a separate metallic badge, that allowed a additional protection against accidental contacts. (IP20), and reduce the damages caused for electrical internal arcing. This badge separates the equipment compartment from the busbars compartment. Multi Function Wall Separator (MFW, Opcional) The widrawable design could introduce a multifunctional separate badge made with insulating material that allowed into achieving an additional protection against accidental contacts. (IP20), and reduce the damages caused for electrical internal arcing. This badge separate the equipment compartment from the vertical distribution busbars, this busbars from the main busbar system (that have horizontal disposition), and also each vertical distribution busbars from the others.

1.4. TESTS PROPOSED (ACCORDING CEI IEC 60439-1) The Standard CEI IEC 60439-1, in its point 8, states the following: 8 Test specifications 8.1 Classification of tests The tests to verify the characteristics of an ASSEMBLY include: - type tests (see 8.1.1 and 8.2) - routine tests (see 8.1.2 and 8.3). The manufacturer shall, on request, specify the basis for the verifications. NOTE Verifications and tests to be performed on TTA and PTTA are listed in table 7. 8.1.1 Type tests (see 8.2) Type tests are intended to verify compliance with the requirements laid down in this standard for a given type of ASSEMBLY. Type tests will be carried out on a sample of such an ASSEMBLY or on such parts of ASSEMBLIES manufactured to the same or a similar design. They shall be carried out on the initiative of the manufacturer. Type tests include the following: a) verification of temperature-rise limits (8.2.1); b) verification of the dielectric properties (8.2.2); c) verification of the short-circuit withstand strength (8.2.3); d) verification of the effectiveness of the protective circuit (8.2.4); e) verification of clearances and creepage distances (8.2.5); f) verification of mechanical operation (8.2.6); g) verification of the degree of protection (8.2.7). These tests may be carried out in any order and/or on different samples of the same type. If modifications are made to the components of the ASSEMBLY, new type tests have to be carried out only in so far as such modifications are likely to adversely affect the results of these tests.

8.1.2 Routine tests (see 8.3) Routine tests are intended to detect faults in materials and workmanship. They are carried out on every new ASSEMBLY after it has been assembled or on each transport unit. Another routine test at the place of installation is not required. ASSEMBLIES which are assembled from standardized components outside the works of the manufacturer of these components, by the exclusive use of parts and accessories specified or supplied by the manufacturer for this purpose, shall be routine-tested by the firm which has assembled the ASSEMBLY. Routine tests include the following: a) inspection of the ASSEMBLY including inspection of wiring and, if necessary, electrical operation test (8.3.1); b) a dielectric test (8.3.2); c) checking of protective measures and of the electrical continuity of the protective circuit (8.3.3). These tests may be carried out in any order.

NOTE: The performance of the routine tests at the manufacturer's works does not relieve the firm installing the ASSEMBLY of the duty of checking it after transport and installation. So, we propose to make the routine test, and to give you test certificates of the type tests. INTERNAL ARCING, ACCORDING TO IEC 61641

Advantages that Offers a Switchgear with Arc Proof Design

The IEC 61641 Standard is called “Guide for Testing Under Conditions of Arcing due to Internal Fault”, and is intended for “Enclosed low-voltage switchgear and controlgear assemblies”. It establishes five criterions that the Low Voltage Switchgear must fulfil and overcome during the respective arc test conditions, in order to get the Type Test Certifications. The criterions are the followings: -Criterion No. 1: Whether correctly secured doors, covers, etc., do not open; -Criterion No. 2: Whether parts (of the ASSEMBLY), which may cause a hazard, do not fly off. (This includes large parts or those with sharp edges, for example inspection windows, pressure relief flaps, cover plates, etc. made of metal or plastic.); -Criterion No. 3: Whether arcing does not cause holes to develop in the freely accessible external parts of the enclosure as a result of burning or other effects; -Criterion No. 4: Whether the indicators arranged vertically do not ignite (indicators ignited as a result of paint or stickers burning are excluded from this assessment); -Criterion No. 5: Whether the equipotential bonding arrangement for accessible parts of the enclosure is still effective. The Standard contemplates: • The effects of the internal pressure that act over the structure, covered, doors, etc; • The thermal effects of the Arcs; • The thermal effects of the hot gases that are emanated and of the incandescent

particles; But it doesn’t cover the 100% of the effects that could be of risk, for example, Toxic gases. For our Switchgear design, besides the cited criterions, ABB adopted the following additional premises: 1. The plastic components used in the assembly should have properties that must

contribute to the Arcing self-extinction. 2. The thermal and mechanical stress in the switchgear should be confined to the arcing

origin place (one module). 3. After of the Arc presence, it should be possible to remove the affected module without

inconvenient, with switch on voltage. 4. The emitted gases should not be poisonous.

5. The Arcing and their consequences should not put in danger the human life. The ABB Switchgears MNS are TTA type (Type Tested Switchgear Assembly), according to IEC 60439-1, with Arc-Proof Design, according to IEC 61641. In case of an internal arcing in one of these switchgear, it would behave in the following way: Human safety: • The emitted gases should be driven toward the Switchgear superior part, and they

would leave to the exterior through the flaps foreseen for this circumstance. • Any person should be hurt or burnt for any element. • The mentioned gases would not be poisonous. Operative safety: • The Arcing effects should remain limited to the place in which the arcs have arisen. • In all moment, the other modules and the total of the switchgear should go on working

normally. • The affected module should be able to be withdrawn normally. • At worst, it could be necessary to replace the module. • If it is necessary to clean the area where the arcing was produced, it could be done in

a programmed way and without difficulty. Conclusion: higher security, reliability and operative continuity, for the process, and higher safety, for the personal (operation and maintenance).

4. REFERENCE LIST The first version of the MNS system was developed more than 25 years ago. Up to now, more than 700.000 cubicles have been sold, all over the world. So, the reference list is very extended, and include nuclear power stations, off shore applications, ships, mines, refineries, etc. Besides this, some companies like Dow Chemical Company, Bayer, Procter & Gamble, Exxon Mobil, etc., have signed global agreements with ABB, and use MNS equipments for all the new factories they're building all over the world. From Argentina, we're supplying MNS switchgears and controlgears not only to the Argentinean market, but also to Brazil, Chile, Uruguay, Bolivia, Mexico, Ecuador, Pilliphines, etc., for some of the most important projects in these countries.
