Mitsubishi HK-KT7M34WBKWS 3-Pole Circuit Breaker 75A 25kA

The Mitsubishi HK-KT7M34WBKWS is a 3-pole molded-case circuit breaker designed for electrical distribution and equipment protection. It features a rated current of 75 Amperes and a short-circuit breaking capacity (Icu = Ics) of 25 kA at 440 V AC, providing reliable overcurrent and short-circuit protection for industrial power circuits. This circuit breaker is suitable for use in factory automation panels, motor control centers, and switchboard installations where dependable circuit protection is required. Its 3-pole configuration allows it to protect all three phases of an AC supply simultaneously. The HK-KT7M34WBKWS is a direct replacement spare part for Mitsubishi electrical distribution systems and can be integrated into existing panel layouts. It is intended for environments that demand consistent interrupting performance under fault conditions, helping to safeguard downstream equipment such as drives, servo amplifiers, and control circuits.
