In the world of power distribution, ensuring the safety and protection of electrical lines and equipment is critical. An important component that plays a key role here is the molded case circuit breaker (MCCB). Molded case circuit breakers are used to prevent power supply equipment from being damaged due to overload, short circuit, undervoltage and other faults. They are also used for infrequent starting of motors and provide protection against overload, short circuit and undervoltage.
