A Molded Case Circuit Breaker is an electromechanical device used to protect electrical circuits from excessive current flow. Unlike fuse-based protection systems, MCCBs can be reset after they trip, making them a more sustainable option for circuit protection. The "molded case" refers to the plastic or composite enclosure that houses the internal components of the circuit breaker, providing both mechanical protection and insulation.
