Molded Case Circuit Breaker (MCCB) is a circuit breaker and trip device
assembled in a mould case. The case functions as both an outer wrapper and to retain in proper position the breaker’s internal components. Theses cases are made from
various types of electrical insulating and fire retardant plastic. MCCB 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.
