Mitsubishi HK-KT634WWS 3-Pole Molded Case Circuit Breaker 63-125A

The Mitsubishi HK-KT634WWS is a 3-pole molded case circuit breaker (MCCB) designed for reliable overcurrent and short-circuit protection in industrial electrical distribution systems. It features an adjustable rated current range of 63 to 125 amperes, allowing flexible configuration to match the specific load requirements of the protected circuit. The breaking capacity is rated at Icu = Ics = 36 kA at 440 V AC, providing robust fault interruption performance suitable for demanding industrial environments. The HK-KT634WWS is intended for use in power distribution panels, motor control centers, and other switchgear assemblies where dependable circuit protection is essential. Its 3-pole configuration makes it appropriate for three-phase AC power systems commonly found in factory automation, process control, and building services applications. As a Mitsubishi-manufactured MCCB, it is engineered for long service life and consistent tripping characteristics under both overload and short-circuit conditions.
