Siemens Q115DF Dual Function AFCI GFCI Circuit Breaker

Siemens Q115DF is a 15 Amp, 1-Pole dual-function AFCI/GFCI circuit breaker designed for 120-volt residential panels. This plug-in Q-Line breaker provides both arc-fault protection (AFCI) and ground-fault protection (GFCI) in a single device, helping to protect branch circuits from arc faults and ground faults. It is listed as UL Type QFGA2 and carries an interrupting rating of 10,000 AIC at 120 V. The Q115DF is the standard plug-in variant; Siemens also offers Q115DFN, the plug-on-neutral version, for circuits requiring a neutral connection at the breaker. Compatible with Siemens Q-Line load centers and other Siemens Q-Series breakers, it supports long-time and instantaneous trip behavior to clear faults while maintaining continuous protection. Typical applications include residential branch circuits in living areas, bedrooms, kitchens, and bathrooms where code or local requirements call for combined AFCI and GFCI protection.
