The 100 amp molded case circuit breaker (MCCB) is a crucial component in electrical systems, providing protection against overloads, short circuits, and other electrical faults. Its significance cannot be overstated, as it ensures the safety and reliability of electrical equipment and prevents potential disasters.

    The 100 amp rating of the MCCB signifies its capacity to handle a maximum current of 100 amperes. This rating is carefully chosen based on the specific requirements of the electrical circuit it is designed to protect. Exceeding this limit can lead to breaker failure or tripping, potentially causing damage to connected equipment or even sparking a fire.
