Siemens QF120AN is a 20-amp, 1-pole ground-fault circuit interrupter (GFCI) breaker that uses a plug-on neutral connection (QPF2N) and operates at 120V AC. It provides GFCI protection by tripping on ground faults at a sensitivity of 5 mA, and has a 10,000 A interrupt rating (10 kAIC) at 120 V. The plug-on neutral design eliminates the need for a separate neutral pigtail during installation, simplifying replacement in compatible Siemens panels. This unit is listed as QF120AN, a Type QPF2N, 20A, 1-Pole GFCI breaker within Siemens' personal protection circuit-breaker lineup.
