Siemens Q220AFCN Plug On Arc Fault Circuit Breaker

Siemens Q220AFCN is a 2-pole, 20-amp arc-fault circuit interrupter (AFCI) with plug-on neutral, part of the Siemens QAFN family designed for residential panelboards. It operates at 120/240 V and provides combination AFCI protection that detects arc faults and trips to reduce fire risk on installed branch circuits. The plug-on neutral configuration eliminates the need for a separate neutral lug during wiring, simplifying installation in compatible Siemens load centers. This unit is UL 1699 listed and offers a 22 kA interrupting capacity (AIC) for 120/240 V circuits, making it suitable for standard residential applications. Designed for plug-in mounting in typical Siemens 2-pole spaces, the Q220AFCN helps ensure AFCI protection on circuits such as living rooms, bedrooms, and kitchens where code requires arc-fault safety.
