Mitsubishi HK-KT7M34WBJ 3-Pole Circuit Breaker 125A

The Mitsubishi HK-KT7M34WBJ is a 3-pole molded-case circuit breaker designed for power distribution and equipment protection in industrial electrical systems. It features a rated current of 125 A and provides a short-circuit breaking capacity (Icu = Ics) of 25 kA at 440 VAC, ensuring reliable interruption of fault currents and safeguarding downstream components. This circuit breaker is suitable for use in switchgear panels, motor control centers, and general-purpose distribution boards where dependable overcurrent and short-circuit protection is required. Its 3-pole configuration supports three-phase AC circuits commonly found in industrial and commercial installations. The HK-KT7M34WBJ is a direct replacement part for Mitsubishi electrical distribution systems and can be integrated into existing panel layouts that accept the same frame size and mounting pattern.
