Mitsubishi HK-KT63WBWS 3-Pole Circuit Breaker 32-40A

The Mitsubishi HK-KT63WBWS (HK-KT63WBWS) is a 3-pole circuit breaker designed for overcurrent and short-circuit protection in industrial electrical distribution systems. It features an adjustable rated current (Ir) range of 32 to 40 amperes, allowing flexible adaptation to varying load requirements. The unit provides an ultimate short-circuit breaking capacity (Icu) and a service short-circuit breaking capacity (Ics) of 36 kA at 440 VAC, ensuring reliable interruption of fault currents in demanding industrial environments. This circuit breaker is suitable for use in motor control centers, power distribution panels, and other industrial switchgear applications where dependable overcurrent and short-circuit protection is required. The 3-pole configuration supports three-phase AC power systems commonly found in industrial facilities. The HK-KT63WBWS is part of Mitsubishi's range of low-voltage circuit breakers engineered for safety and durability in continuous industrial operation. Its equal Icu and Ics ratings indicate full-performance breaking capability under service conditions.
