Mitsubishi HK-KT7M3UWB 2-Pole Automatic Circuit Breaker 20A 600VAC

The Mitsubishi HK-KT7M3UWB is a 2-pole automatic circuit breaker rated at 20 amperes with a maximum voltage of 600 volts AC. Designed for use in electrical distribution and protection systems, this breaker provides reliable overcurrent and short-circuit protection for downstream equipment and wiring. The 2-pole configuration allows it to simultaneously interrupt two live conductors, making it suitable for single-phase and certain multi-phase circuit applications. Mitsubishi circuit breakers are widely used in industrial control panels, motor control centers, and power distribution boards, offering dependable performance in demanding environments. The HK-KT7M3UWB is a direct replacement part for installations originally equipped with this model and is compatible with corresponding Mitsubishi breaker mounting systems. Its 600 VAC rating makes it appropriate for a range of industrial voltage levels commonly found in North American and international electrical systems. This circuit breaker helps ensure safe, controlled disconnection of electrical circuits under fault conditions, safeguarding personnel and connected equipment.
