Miniature Circuit Breaker(MCB)
MCBs are electromechanical devices that are used to protect an electrical circuit from an overcurrent. It can be reclosed without any hand-operated restoration. MCB is used as an option to the fuse switch in most of the circuits. A circuit breaker (popularly known as CB) is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow.
