Mitsubishi HK-KT7M3UWBJWS No-Fuse Circuit Breaker 3-Pole 5A 240VAC

The Mitsubishi HK-KT7M3UWBJWS is a no-fuse circuit breaker (molded-case circuit breaker) designed for overcurrent protection in industrial and commercial electrical installations. This three-pole breaker is rated at 5 amperes with a 240 VAC operating voltage, making it well suited for protecting branch circuits, control panels, servo drive supply lines and other low-current three-phase loads commonly found in Mitsubishi automation systems. No-fuse circuit breakers eliminate the need for replaceable fuse elements, simplifying maintenance and enabling rapid manual reset after a fault condition is cleared. The compact three-pole construction allows the HK-KT7M3UWBJWS to interrupt all three phases simultaneously, providing balanced protection and safe disconnection. Typical applications include machine-tool control cabinets, CNC equipment, conveyor systems and other automated production lines where reliable short-circuit and overload protection is essential. The breaker can be DIN-rail or panel mounted for convenient integration into new or existing switchgear assemblies.
