Molded Case Circuit Breaker

MCCBs(Molded Case Circuit Breaker) also known as thermal magnetic circuit breaker are used to provide circuit protection in applications requiring adjustable tripping, high current, and manual tripping of the circuit. They are often used in industrial applications such as panelboards, switchboards, motor control centers, and control panels.

the product Standard: IEC/EN 60947 2

MCCBs(Molded Case Circuit Breaker) have two working principles: an electromagnetic element, protecting against overcurrent (short circuit), and a thermal element, protecting from electrical overload. also can be equipped with Auxiliaries like shunt release(shunt trip circuit breaker), alarm and auxiliary contact for remote control function.
