Service positionThis means that if unit's locking device is at locked position, primary & secondary plug of main circuit, control circuit plug are connected to respective circuit.

Disconnected positionControl circuit plug, primary & secondary plug of main circuit are disconnected. However, the unit cannot be withdrawn from the MCC by mechanical mechanism.

Test positionAt test position, only control circuit plug and socket are connected and you can check all control unit output signal.

Withdrawable positionPlug and socket of control unit, primary & secondary plug of main circuit, mechanical mechanism are disconnected. So the unit can be completely withdrawn from the MCC.

Internal form of separation

Prevention fault spread by metal partitions (Up to form 4b type 7)

Form 4b structure

• Separation of busbar from the functional units

• Separation of functional units from one another

• Separation of terminals of functional units

• Terminals are not in the same compartment as functional unit

Susol LV Switchgear form 4b type 5 & 7 structure

Type 7

Type 5

• Busbar separation is by metallic or non-metallic rigid barriers or partitions.

• The termination for each functional unit has its own integral glanding facility.

• Busbar separation is by metallic or non-metallic rigid barriers or partitions.

• Terminals are separated by insulated coverings.
