Availability:
Quantity:

Cast case circuit breakers, and also MCCBs, are electrical protection devices employed to protect the electrical signal from excessive current, which could cause overloads or quick circuits. Molded case circuit breakers are available for many voltages and frequencies using adjustable trip settings. The MCCB uses a new temperature sensitive device (the thermal element) which has a current sensitive electromagnetic apparatus (the magnetic element) to produce the trip mechanism with regard to protection and isolation. In addition to tripping mechanisms, MCCBs may also be used as manual disconnection switches in the event of emergency or preservation operations.
