Schneider Electric QO120CAFI Plug-In Circuit Breaker

Schneider Electric’s Square D QO120CAFI is a 1-pole, 20-amp arc-fault circuit interrupter (AFCI) breaker designed for 120-volt circuits in QO plug-in panels. It delivers combination arc-fault protection (CAFI) to help detect and interrupt arcing faults on branch circuits, reducing fire risk in wiring. The device is a plug-in QO breaker with a plug-on neutral design and a shorter footprint that speeds installations; a pigtail neutral variant is available and the unit is TAA compliant. Rated for 120 VAC operation, it provides a 10 kA interrupting rating (AIC), ensuring robust protection against short-circuit events. The QO120CAFI is suitable where AFCI protection is required on a 120 V, 20 A circuit and is part of Schneider Electric’s QO family designed for replacement in compatible Square D panelboards.
