Molded case circuit breakers, or even MCCBs, are electrical protection devices helpful to protect the electrical enterprise from excessive current, which could cause overloads or quick circuits. Molded case circuit breakers may be used for a wide range of voltages and frequencies by using adjustable trip settings. The MCCB uses some sort of temperature sensitive device (the thermal element) which includes a current sensitive electromagnetic machine (the magnetic element) to supply the trip mechanism for protection and isolation. In combination with tripping mechanisms, MCCBs can also be used as manual disconnection switches in case of emergency or servicing operations.
