Miniature Circuit Breakers (MCBs)
A miniature circuit breaker (MCB) is a type of electrical breaker that is designed to protect electrical circuits from damage due to overloading, short-circuiting, or other electrical faults. MCBs are commonly used in residential and light commercial electrical systems, and are typically smaller in size than traditional circuit breakers.
