Mitsubishi HK-KT63WBKWS 3-Pole Circuit Breaker 25-32A

The Mitsubishi HK-KT63WBKWS is a 3-pole molded-case circuit breaker designed for industrial power distribution and electrical equipment protection. It features an adjustable rated current (Ir) range of 25 to 32 amperes, allowing flexible configuration to match the protected circuit's requirements. The unit offers an ultimate short-circuit breaking capacity (Icu) equal to the service short-circuit breaking capacity (Ics) of 36 kA at 440 VAC, ensuring reliable and full-performance interruption under fault conditions. This circuit breaker is suitable for use in factory automation panels, motor control centers, and general-purpose switchgear where dependable overcurrent and short-circuit protection is required. Its 3-pole configuration supports three-phase AC power systems commonly found in industrial installations. The HK-KT63WBKWS is a direct replacement part for Mitsubishi electrical distribution systems and integrates with standard DIN-rail or panel-mount configurations typical of Mitsubishi low-voltage switchgear.
