Mitsubishi Electric NF50-KC Shunt Trip Circuit Breaker

The Mitsubishi Electric NF50-KC Shunt Trip Circuit Breaker is a three-pole, no-fuse protective device rated for 50 A and up to 500 V, suitable for 50/60 Hz electrical systems. It integrates a shunt-trip mechanism for remote or automatic tripping, allowing fast, controlled disconnection of power in safety interlock or emergency shutdown scenarios without relying on external fuses. With a 50 A rating and 500 V maximum voltage, this unit is designed for industrial power distribution and control panels where reliable overcurrent protection must coexist with remote shutoff capability, particularly on three-phase circuits common to 50/60 Hz networks. The NF50-KC is intended for use in electrical distribution boards and control panels where remote trip functionality is required alongside standard protective performance, enabling integration with safety circuits or automation schemes while maintaining robust protection for 50 A circuits.
