Schneider Electric - Square D HomeLine 20 amps Surge Single Pole Circuit Breaker

Siemens’ 20‑amp dual‑function single‑pole circuit breaker (model Q120DF / Q120DFP or Q120DFN, Q series) is a single‑pole molded‑case breaker that combines arc‑fault (AFCI) and ground‑fault (GFCI) protection in one device, typically used for kitchen and laundry circuit codes. It protects against both parallel and series arc faults as well as Class‑A 5 mA ground faults on 120 V branch circuits, with 10 kAIC interrupting rating.

The Square D Homeline 20 Amp Dual Function Circuit Breaker provides advanced protection by combining CAFI and GFCI (Class A) technologies into a single device, ensuring compliance with all code requirements while saving space and installation time. Designed for quick and easy setup, its pigtail neutral design connects directly to the neutral bar, allowing seamless power-up in Homeline load centers while also being compatible with plug-on neutral load centers. This single-pole breaker operates on 120/240V AC circuits and is ideal for residential branch circuits supplying wall receptacles, lighting fixtures, dishwashers, and disposals. Engineered for superior circuit protection, it effectively prevents overloads, short circuits, and dangerous arc and ground faults. Featuring a compact design that occupies just one space in the load center, it boasts a 20A current rating, 10kA breaking capacity, and UL-listed safety certification. Dimensions: 3.13" H x 1" W x 2.98" D.

Square D Homeline 20 amp 1-pole Plug-On-Neutral Combination Arc Fault Circuit Interrupters (CAFI) helps keep people and property safe from the effects of dangerous arcing. These arcs typically occur out of sight, inside walls or electrical devices, day or night. Designed for reliability, the Homeline Plug-on Neutral CAFI Circuit Breaker connects directly to the neutral bar, providing a time and labor-saving installation. Several advantages from the Plug-on Neutral design are fewer connections which lead to faster installation and an innovative neutral clip eliminates pigtails which in turn frees gutter space. The Square D CAFI circuit breaker uses a state-of-the-art Arc Detection Technology to continuously monitor the circuit and quickly turn-off the power (trip) when a dangerous condition is detected. Best of all, this technology is combined with Square D's robust and reliable short circuit/overload protection systems in a small, compact package. Engineered for Value and built for Quality, the market leading Square D brand Homeline Combination Arc Fault Circuit Interrupter combine time-tested performance with state-of-the-art technology to provide one of the safest circuit breakers available today.
