QJH22B125 - 125Amp Circuit Breaker

QJH22B125 - 125Amp Circuit Breaker

The QJH22B125 is a 2-pole, 125-amp molded case circuit breaker designed for use in your compatible 120/240VAC electrical distribution systems. With a 22kA interrupting rating, it helps you protect circuits from overloads and short circuits while matching the electrical requirements of existing equipment. This breaker includes load-side lugs for field installation and carries an HACR rating for approved heating, air conditioning, and refrigeration applications. Rated for operation in 40°C ambient conditions, the QJH22B125 is built to last and is intended as a form, fit, and functional replacement where the original breaker specifications call for a Type QJH device.
