Siemens QA120AFC is a 20-amp, 120-volt, single-pole combination AFCI circuit breaker designed for residential panels, providing arc-fault protection in addition to overcurrent protection for branch circuits. It features a plug-on design with a pigtail lead for connection and carries a 10 kA interrupt rating, reflecting its ability to interrupt at high fault currents. This 1-pole AFCI breaker is intended for use in Siemens load centers that accept QA family devices, making it suitable for protecting circuits that serve outlets and lighting where AFCI protection is required.
