The Siemens QA120AFC is a 20-amp, 1-pole, 120V combination arc fault circuit interrupter (AFCI) breaker for Siemens QP and QT load centers. At 20 amps, it is the standard choice for kitchen small appliance circuits, laundry circuits, and bathroom circuits that require both AFCI protection and higher ampacity. The QA120AFC meets NEC 210.12 combination AFCI requirements and provides protection against both series and parallel arc faults. Its plug-in design, pigtail neutral, and TEST button make it easy to install and verify in any Siemens QP or QT load center.
