QJ22B125H - 125Amp Circuit Breaker

QJ22B125H - 125Amp Circuit Breaker

The QJ22B125H is a 2-pole, 125-amp molded case circuit breaker designed for use in your 120/240VAC electrical distribution systems. Built to provide dependable circuit protection against overloads and short circuits, this breaker features a 42kA interrupting capacity at 120/240VAC, making it suitable for applications where higher available fault current requires a matching interrupting rating. As a Type QJ2H breaker, it is intended as a form, fit, and functional replacement for compatible electrical equipment and panelboards requiring this configuration. Rated for 40°C operation, HACR applications, and supplied with load-side lugs, the QJ22B125H is built to last and helps you simplify installation and maintenance in commercial and industrial electrical systems where the original specifications must be maintained.
