Miniature Circuit Breaker or MCB is an automatically operated electrical switch to protect from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operated once and then must be replaced, a circuit breaker can be reset to resume operation.

MCB usually comes in three curves B,C and D –

B – Resistive load, used for low load like fans and lights

C – Inductive load, used for medium load like Air conditioners and Geysers

D – Heavy load, used in motors and transformers
