An mcb or miniature circuit breaker is an electromagnetic device that embodies complete enclosure in a molded insulating material.
A breaker is a resettable protective device that protects against two types of overcurrent situations. First left hand side power terminal then bimetallic strip then current coil or trip coil then moving contact then fixed contact and lastly right had side power terminal. Mcb miniature circuit breaker is a re settable device designed to protect a circuit from short circuits and overcurrents.
