MCCB is the abbreviation for Molded Case Circuit Breaker. It is an important type of electrical protection used when the load current crosses the limitation of a miniature circuit breaker, also called MCB. The MCCB offers safety against overload and short circuit faults, which are extensively used for switching the circuits. It can be used in devices of any current rating that needs…
