Cast case circuit breakers, or MCCBs, are electrical protection devices used to protect the electrical enterprise from excessive current, which will cause overloads or brief circuits. Molded case circuit breakers work extremely well for many voltages and frequencies along with adjustable trip settings. The MCCB uses a new temperature sensitive device (the thermal element) which has a current sensitive electromagnetic device (the magnetic element) to provide the trip mechanism for protection and isolation. Additionally tripping mechanisms, MCCBs may also be used as manual disconnection switches should of emergency or protection operations.
