MCB is an automatic switch that opens when excessive current flows through the circuit. It can be reclosed without any manual replacement. In the case of a fuse, once it has been operated, it must be replaced or rewired, depending on the type of the MCB.

The primary function of a miniature circuit-breaker is to protect an installation or appliance against sustained overloading and short-circuit faults, but it will also give protection against earth faults provided that the earth fault loop impedance is low enough.
