QJH22B175 - 175Amp Circuit Breaker

QJH22B175 - 175Amp Circuit Breaker

The QJH22B175 is a 2-pole, 175-amp molded case circuit breaker designed for use in your 120/240VAC electrical distribution systems. Built to provide dependable overcurrent and short-circuit protection, this Type QJH circuit breaker is a direct form, fit, and function replacement for compatible electrical equipment. With a 22kA interrupting capacity at 120/240VAC, it is well suited for your commercial and industrial applications where the system's available fault current falls within its rated capacity. Designed for operation in 40°C ambient environments, this breaker is also HACR rated for use in heating, air conditioning, and refrigeration equipment where permitted by applicable codes. The included load-side lugs help you to simplify installation, while its durable molded case construction is built to last in demanding electrical environments.
