Arc Fault Breakers

An arc fault circuit interrupter (AFCI) breaker shuts off a circuit when it detects dangerous arcing from damaged cords, loose connections or a nail through a wire, a common cause of electrical fires. The National Electrical Code (NEC 210.12) requires AFCI protection on most 15 and 20 amp, 120-volt circuits in homes, including bedrooms, living rooms, kitchens, hallways and laundry areas.

Choose by panel brand and type:

  • Eaton BR (1-inch): BRN115AF, BRN120AF, BRP115AF, BRP120AF
  • Eaton CH (3/4-inch): CHFN115AF, CHFN120AF
  • Square D QO: QO115PAF, QO120PAF
  • Square D Homeline: HOM115CAFI, HOM120CAFI, HOM115PCAFI, HOM120PCAFI
  • Siemens: QA115AFC, QA120AFC, QA115AFCN, QA120AFCN

Pigtail or plug-on neutral? Pigtail AFCIs have a coiled white wire that connects to the panel's neutral bar. Plug-on neutral AFCIs clip directly onto a neutral rail and need a plug-on neutral panel.

Need ground fault protection too? Our dual function AFCI/GFCI breakers combine both in one breaker.
