Schneider Electric QOB120VHCAFI Arc Fault Circuit Breaker

Schneider Electric's Square D QOB120VHCAFI is a bolt-on, 1-pole AFCI circuit breaker for QO panelboards that delivers 20 A at 120/240 V with a 22 kA interrupting rating. It uses a neutral pigtail for combination arc-fault protection (CAFI) and is UL-listed and TAA-compliant, making it suitable for residential and light commercial branch circuits that require arc-fault protection in the QO family. The device provides both series and parallel arc-fault detection, helping to reduce nuisance trips while safeguarding wiring, and is designed specifically for bolt-on installation in compatible QO load centers. Typical applications include branch circuits feeding living spaces, outlets, and lighting where AFCI protection is mandated by code.
