The Schneider Electric Square D QO115CAFI is a 15-amp, 1-pole arc-fault circuit interrupter (AFCI) breaker designed for 120-volt residential wiring within Square D QO load centers. As a CAFI device, it provides combination arc-fault protection—detecting both series and parallel arcing—and offers up to a 10 kA interrupt rating for typical branch circuits, helping mitigate fire risk from electrical faults. Designed for use in residential panels, this 120/240-volt AFCI breaker protects individual circuits and supports NEC AFCI protection requirements for modern homes.
