Cast case circuit breakers, or maybe MCCBs, are electrical protection devices utilized to protect the electrical enterprise from excessive current, which will cause overloads or short circuits. Molded case circuit breakers may be used for a wide range of voltages and frequencies together with adjustable trip settings. The MCCB uses the temperature sensitive device (the thermal element) using a current sensitive electromagnetic apparatus (the magnetic element) to provide the trip mechanism intended for protection and isolation. As well as tripping mechanisms, MCCBs can even be used as manual disconnection switches in the event that of emergency or servicing operations.
