No, they are not interchangeable. The QGA32125 uses Square D's I-Line plug-in bus connection system, designed for commercial/industrial I-Line panelboards and switchboards. QO breakers use a completely different plug-in stab and are intended for residential/light-commercial QO loadcentres. Always match the breaker series to your panelboard's specified breaker type.
Square D has transitioned many QGA-frame products over the years. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so even if the QGA32125 is no longer in current production, we maintain stock of new, reconditioned, and legacy units. Contact us or visit one of our Calgary, Edmonton, or Vancouver counters for availability.
The QGA32125 can serve as either a feeder or branch breaker within a Square D I-Line panelboard, depending on the panel's design and the application's load requirements. Whether it is suitable as a main disconnect depends on the specific panelboard configuration and local electrical code (CEC) requirements. We recommend confirming the intended application with your panel documentation or contacting us for guidance.
