MINIATURE CIRCUIT BREAKER

MCB (Miniature Circuit Breaker) is an electromechanical device which protects an electrical circuit from overcurrent and overload conditions. Unlike a fuse, an MCB can be reused after clearing the fault; offering im-proved operational safety and greater convenience without incurring large operating costs.
