Siemens QF115A Ground Fault Circuit Breaker 1 Pole

Siemens QF115A is a 15-amp, 120-volt, single-pole ground-fault circuit interrupter (GFCI) breaker that plugs into compatible Siemens QF load centers to provide dedicated ground-fault protection for individual branch circuits. Rated for up to 10,000 A interrupt capacity (10 kAIC) and designed for 60 Hz operation, it trips when a ground fault is detected, helping to reduce the risk of shock in wet or damp environments. This 1-pole, plug-in design typically occupies one panel space and, in certain package variants, includes a neutral pig-tail for connection to the panel neutral; some listings also note self‑test functionality to periodically verify GFCI operation. Common applications include receptacle circuits in bathrooms, kitchens, laundry rooms, garages, basements, and outdoor outlets where GFCI protection is required by code. The QF115A is compatible with Siemens Type QF panels and other Siemens load centers that support the QF series, providing a straightforward replacement for standard breakers while delivering enhanced safety through ground-fault protection on 120‑V circuits.
