     Molded Case Circuit Breaker (MCCB) is a circuit breaker and trip device assembled in a mould case. Also it  can automatically cut off electric power in case of overload and short circuit. It is meant for higher rated current and is commonly used in Industrial applications. Its usual range is 250A-800A.

    Molded case circuit breakers are a type of electrical protection device that is commonly used when load currents exceed the capabilities of miniature circuit breakers. They are also used in applications of any current rating that require adjustable trip settings, which are not available in plug-in circuit breakers and MCBs.MCCB means Moulded case Circuit Breaker -- it is used for 25oAmps to 800Amps.
