Mitsubishi HK-KT43WKWS Molded Case Circuit Breaker WSS/WS-V Series 2-Pole 5A

The Mitsubishi HK-KT43WKWS is a molded case circuit breaker (MCCB) belonging to the WSS/WS-V series. Built on a 100 ampere frame, this breaker is rated for 5 amperes of continuous current at up to 480 volts AC in a 2-pole configuration. It is designed to provide reliable overcurrent and short-circuit protection for branch circuits within electrical distribution systems. The WSS/WS-V series from Mitsubishi is engineered for compact installation and consistent interrupting performance across a range of industrial and commercial applications. With a 100 A frame housing a 5 A trip rating, the HK-KT43WKWS is well suited for protecting lower-current circuits fed from larger distribution panels. Its 2-pole design accommodates single-phase AC loads. This circuit breaker is commonly used in factory automation panels, machine tool electrical enclosures, and building electrical infrastructure where Mitsubishi switchgear standards are specified.
