Eaton - 20 amps 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.

Siemens Q120 20 Amp Single-Pole Circuit Breakers offer thermal-magnetic protection for standard 120V branch circuits in QP load centers and compatible Murray panels. Rated at 10kAIC for overloads and short circuits, they support #14-4 AWG Cu/Al wire with Insta-Wire push-in terminals for fast installation on lights, outlets, or appliances. UL/CSA listed with toggle actuation for reliable residential use.

Siemens Type QD circuit breakers are UL classified for use in specific Square D load centers in place of Square D QO circuit breakers (see listing on back).For easy reference, a panelboard compatibility list is provided with each circuit breaker. All QD breakers are supplied with load side connectors suitable for 60/75C wire and are calibrated for 40C maximum ambient applications.
