Mitsubishi HK-KT7M3G1-1-20 3-Pole Circuit Breaker 125-160A

The Mitsubishi HK-KT7M3G1-1-20 is a 3-pole molded case circuit breaker designed for reliable overcurrent and short-circuit protection in industrial electrical distribution systems. It features an adjustable rated current (Ir) ranging from 125 to 160 amperes, making it suitable for a variety of power distribution and motor protection applications where flexibility in current settings is required. This circuit breaker offers a rated ultimate short-circuit breaking capacity (Icu) equal to its rated service short-circuit breaking capacity (Ics) of 36 kiloamperes at 440 volts AC, ensuring full performance under fault conditions without degradation. The equal Icu and Ics values indicate that the breaker can maintain its protective characteristics even after interrupting a fault at its maximum rated capacity. The HK-KT7M3G1-1-20 is intended for installation in industrial switchgear panels, motor control centers, and power distribution boards where dependable circuit protection and operational safety are essential.
