Mitsubishi HK-KT7M3G7-1-11 3-Pole Molded Case Circuit Breaker 225A

The Mitsubishi HK-KT7M3G7-1-11 is a 3-pole molded case circuit breaker (MCCB) designed for the protection of electrical circuits in industrial and commercial power distribution systems. It features a rated current of 225 amperes, making it suitable for medium-power branch and feeder circuit protection. The breaker offers an ultimate short-circuit breaking capacity (Icu) equal to its service short-circuit breaking capacity (Ics) of 36 kA at 440 V AC, ensuring full performance reliability under fault conditions. This circuit breaker is intended for use in switchgear panels and motor control centers where dependable overcurrent and short-circuit protection is required. Its equal Icu and Ics ratings indicate that the breaker remains fully operational after interrupting a fault at its maximum rated capacity. The HK-KT7M3G7-1-11 is a direct replacement part for Mitsubishi electrical distribution equipment and is suitable for a wide range of three-phase AC power applications.
