Mitsubishi HK-KT7M3G1-1-5 3-Pole Circuit Breaker 140-200A

The Mitsubishi HK-KT7M3G1-1-5 is a 3-pole circuit breaker designed for power distribution and equipment protection in industrial electrical systems. It features an adjustable rated current (Ir) range of 140 to 200 amperes, allowing flexible overcurrent protection settings to match the load requirements of the protected circuit. The unit 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 interruption even under severe fault conditions. This circuit breaker is suitable for use in motor control centers, switchboards, and panel-board applications where reliable short-circuit and overload protection is required. Its equal Icu and Ics ratings indicate that the breaker can continue to operate at its rated performance level after clearing a fault at its maximum breaking capacity. The HK-KT7M3G1-1-5 is part of Mitsubishi's range of molded-case circuit breakers and is intended for installation in systems operating at up to 440 V AC. It provides dependable circuit protection for a wide variety of commercial and industrial power distribution environments.
