Siemens Q120DFWG Circuit Breaker – Q Series – 20A – 1 Pole – 120VAC – Plug-In – Dual Function (AFCI + GFCI)

The Siemens Q120DFWG is a Q Series molded case residential circuit breaker designed for advanced safety protection in load center applications. Rated at 20A and 120VAC, this 1-pole plug-in breaker provides dual protection by combining Arc Fault Circuit Interruption (AFCI) and Ground Fault Circuit Interruption (GFCI) in a single device.

Engineered for residential electrical systems, this breaker uses a thermal-magnetic mechanism along with electronic sensing to detect both arc faults and ground faults, enhancing protection against electrical fires and shock hazards. Its plug-in design ensures compatibility with Siemens load centers for quick and secure installation.
