Molded Case Circuit Breaker (MCCB)

A Molded Case Circuit Breaker (MCCB) is a heavy-duty protection device used to safeguard electrical circuits from overload, short-circuit, and earth faults. MCCBs have a higher current rating than MCBs and are commonly used in industrial, commercial, and large electrical distribution systems.
