QGA32150 - 150 Amp Circuit Breaker

QGA32150 - 150 Amp Circuit Breaker

The QGA32150 is a 150 amp, 3-pole Q-Frame molded case circuit breaker with an I-Line plug-on connection and a thermal magnetic trip unit. It's intended for use in compatible three-phase electrical distribution systems where dependable overcurrent protection is needed. The thermal element responds to overload conditions, while the magnetic trip reacts almost instantly during higher fault currents.

With a 65kA interrupting rating at 240VAC, this breaker is suited for applications where available fault current exceeds the capability of standard-duty breakers. Its plug-on mounting also makes it a practical replacement in compatible I-Line panelboards, whether you're replacing a failed unit or performing scheduled maintenance.

If you're matching an existing breaker, the important specifications are the frame type, amperage, pole count, interrupting rating, and mounting style. The QGA32150 combines all of those in a single unit for installations that call for a Q-Frame, 150A, 3-pole I-Line breaker.
