Siemens AG QF115AN Ground-Fault Circuit Breaker

Siemens QF115AN is a 15-amp, 120-volt, 1-pole ground-fault circuit interrupter (GFCI) designed for general-purpose protection of 120V branch circuits. This plug-in, plug-on-neutral device provides 5 mA ground-fault protection (Class A) with a 10,000-amp interrupt rating at 120 V, making it suitable for locations where personnel protection is required. The breaker accepts copper conductors 14 to 10 AWG and aluminum conductors 12 to 10 AWG, and it offers a load-lug terminal option for pass-through wiring; it mounts in compatible Siemens panels with standard plug-in installation. Typically used on 120V circuits in residential, commercial, or light industrial applications such as kitchens, bathrooms, laundry rooms, or other areas where GFCI protection is mandated or advisable, the QF115AN combines Siemens reliability with a compact 1-pole form factor for easy replacement in existing load centers.
