QJ22B100 - 100Amp Circuit Breaker

QJ22B100 - 100Amp Circuit Breaker

The QJ22B100 is a 2-pole, 100-amp molded-case circuit breaker designed for your electrical systems that require a Type QJ breaker rated for 120/240 VAC service. It helps you protect circuits from overloads and short circuits while matching the form, fit, and function of compatible equipment already in service. With a 10 kA interrupting rating, a 40°C ambient rating, and an HACR designation, it's commonly used in commercial and industrial distribution equipment, as well as in your compatible HVAC applications. This breaker also comes with load-side lugs, making installation more straightforward. Built with a molded-case housing, it's designed for dependable, long-term use in the environments it serves.

Where It Works Best

• The QJ22B100 is commonly installed in compatible panelboards, switchboards, and electrical distribution equipment operating at 120/240 VAC. It's a good choice when replacing an existing Type QJ breaker in commercial, industrial, or institutional facilities where a 100-amp, 2-pole configuration is required. Because it carries an HACR rating, it can also be used in compatible heating, ventilation, air conditioning, and refrigeration equipment. When the original equipment calls for this breaker style and rating, the QJ22B100 provides the proper form, fit, and function without changing the existing system design.
