Schneider Electric QOB120CAFI Molded Case Circuit Breaker

Schneider Electric QOB120CAFI is a 1‑pole, 20‑amp molded‑case circuit breaker that provides combination arc‑fault protection for 120 VAC circuits. Built for bolt‑on mounting in Square D/QOB panels, it includes a neutral pigtail for older installations and carries TAA compliance. Rated for 120 VAC with a 10 kA interrupting capacity, this CAFI breaker detects arc faults across series and parallel arcs to help prevent electrical fires. Use it on lighting and receptacle circuits in residential or light commercial settings where AFCI protection is required by code; it’s compatible with the QOB family and designed for retrofit or panel additions that demand arc‑fault protection without changing the panel. The unit is designed to save space while delivering reliable overcurrent and arc protection on a single‑pole 120 V circuit.
