MCCB stands for Molded Case Circuit Breaker which provides protection against overload, short circuit faults and is also used for switching the circuits. The wide current ratings and high breaking capacity in MCCB find their use in industrial applications.
MCCB can be used for protection of capacitor bank, generator protection and main electric feeder distribution. It offers adequate protection whenever an application requires discrimination, adjustable overload setting or earth fault protection.
