Mitsubishi HK-KT7M34WJWS Molded Case Circuit Breaker with 120V AC Shunt Trip Coil

The Mitsubishi HK-KT7M34WJWS is a molded case circuit breaker (MCCB) supplied with a pre-installed shunt trip coil rated at 120 volts AC. Molded case circuit breakers are essential protective devices used in electrical power distribution systems to safeguard circuits against overloads and short-circuit faults. The integrated shunt trip coil allows the breaker to be remotely tripped when an external signal energizes the coil, providing an additional layer of safety for emergency shutdown systems, fire alarm interfaces and other critical applications. This unit is manufactured by Mitsubishi Electric and is designed for use within low-voltage switchgear and distribution panels. The pre-installed shunt trip eliminates the need for separate field installation of the trip accessory, simplifying panel assembly and reducing wiring time. The HK-KT7M34WJWS is suitable for commercial, industrial and infrastructure electrical installations where reliable circuit protection and remote tripping capability are required.
