A molded case circuit breaker (MCCB) is a type of breaker that protects electrical circuits from overcurrents arising from circuit overload, short circuits, or faulty wiring. They are almost the same as the Miniature circuit breaker (MCB) as they do the same work. However, MCCB is more advanced. It has a higher current rating of up to 2500, Amp, and adjustable trip settings.

Circuit Breakers are reusable overcurrent protection devices. After tripping to break the circuit, the breaker can be reset to protect the circuit again. There are two accepted definitions for circuit breakers. The National Electrical Manufacturers Association (NEMA) defines a circuit breaker as a device designed to open and close a circuit, by ...
