MOLDED CASE CIRCUIT BREAKERS (MCCB)

Molded case circuit breakers are electrical protection devices that are designed to protect the electrical circuit from excessive current. This excessive current can be caused due to an overload or short circuit. The molded case circuit breakers can be used in a wide range of voltages and frequencies with a defined lower and upper limit of adjustable trip settings. In addition to tripping mechanisms, MCCBs can also be used as manual disconnection switches in case of emergency or maintenance operations. MCCBs are standardized and tested for overcurrent, voltage surge, and fault protection to ensure safe operation in all environments and applications. They work effectively as a reset switch for an electric circuit to disconnect power and minimize damage caused by a circuit overload, ground fault, short circuits, or when current exceeds the current limiting.

M:Moulded case circuit breaker
1:Design No
□:Rated current of frame
□:Breaking capacity characteristic code/S denotes standard type (S can be omitted)H denotes higher type

Note: There are four types of neutral pole (N pole) for four phases product.The neutral pole of type A is not equipped with over-current tripping element, its always switched on, and it is not switched on or off together with other three poles.
The neutral pole of type B is not equipped with over-current tripping element, and it’s switched on or off together with other three poles(the neutral pole is switched on before being switched off)The neutral pole of type C is equipped with over-current tripping element, and it’s switched on or off together with other three poles(the neutral pole is switched on before being switched off) The neutral pole of type D is equipped with over-current tripping element, it’s always switched on and is not switched on or off together with other three poles.
