Molded case circuit breakers, as well as MCCBs, are electrical protection devices helpful to protect the electrical enterprise from excessive current, which could cause overloads or limited circuits. Molded case circuit breakers are available for a wide range of voltages and frequencies along with adjustable trip settings. The MCCB uses any temperature sensitive device (the thermal element) using a current sensitive electromagnetic device (the magnetic element) to produce the trip mechanism regarding protection and isolation. As well as tripping mechanisms, MCCBs will also be used as manual disconnection switches in the event of emergency or upkeep operations.
