Molded Case Breakers (MCCBs)

Molded Case Breakers (MCCBs)

A molded case circuit breaker (MCCB) is a type of electrical breaker that is used to protect electrical systems from damage due to overloading, short-circuiting, or other electrical faults. MCCBs are commonly used in industrial and commercial electrical systems, and are designed to handle higher currents and voltage levels than residential miniature circuit breakers.
