Siemens QF120AN is a 20-amp, 120-volt, 1-pole GFCI circuit breaker designed for Siemens plug-on neutral load centers. The device provides ground-fault protection and uses a plug-on neutral connection (QPF2N) to connect the neutral conductor directly to the breaker, eliminating the need for a separate neutral pigtail. It is rated for 10,000 AIC and is part of Siemens' QF family, designed to protect 120V circuits in residential electrical systems that require GFCI protection.
