QJ23B150H - 150Amp Circuit Breaker

QJ23B150H - 150Amp Circuit Breaker

Finding the right replacement breaker isn't just about matching the amperage. The QJ23B150H is a 3-pole, 150-amp molded-case circuit breaker designed for applications requiring a 42 kA interrupting rating at 240 VAC. If you're maintaining an existing electrical system, this breaker provides the form, fit, and function needed for compatible equipment without requiring changes to the original installation. Built for 40°C ambient conditions and HACR rated, the QJ23B150H is commonly used in commercial and industrial electrical systems, including qualifying HVAC applications. It also comes with load-side lugs, making conductor termination more straightforward during installation. As with any replacement breaker, confirm that the electrical ratings and breaker type match your equipment before putting it into service.
