![]() It is another type of electrical protection device which is used when load current exceeds the limit of a miniature circuit breaker. MCCB stands for Molded Case Circuit Breaker. MCB works on bi-metal respective principle which provides protection against overload current&solenoidshort circuit current. MCB can be reset very fast & don’t have any maintenance cost. Handling MCB is quite safer and it quickly restores the supply.When it comes to house applications, MCB is the most preferred choice for overload and short circuit protection. The MCB is an electromechanical device which guards the electric wires &electrical load from overcurrent so as to avoid any kind of fire or electrical hazards. However, fuse may sense these conditions but it has to be replaced though MCB can be reset. It automatically switches OFF electrical circuit during any abnormal condition in the electrical network such as overload & short circuit conditions. MCB stands for Miniature Circuit Breaker. Before knowing about the difference among all, let’s get to know about them a little bit. MCB, MCCB, RCCB, and ELCB are circuit breakers but all of them are designed for serving a specific purpose. ![]()
