They work flawlessly and I upgraded 2 of these breakers (4 total) from AFCI to dual feature in about 10 minutes -- and given that I'm not an electrician, this was pretty easy. I tested both with the test button and an AFCI/GFCI testing tool on the receptacles and it was great. They are about the same size, so easily fit in the breaker box. It's only been about 30 hours since installing, but the breaker hasn't tripped, so I'm very happy. Note: It's important for safety: If you are installing these in a subpanel, make sure that your ground wires and your neutral wires do not go to the same bar in the panel -- it's very dangerous! Grounds go to one, neutrals (pigtails) go to the other! Review: Great Product - These are OEM original new equipment and work as designed. Not sure how desertcart can offer them at half the cost of my husband's suppliers but I'm glad he decided to check. Looks like desertcart has a distributor status with Siemens though so he'll be checking everything on here now. ## Features - Siemens Q120DF 20-Amp Afci/Gfci Dual Function Circuit Breaker, Plug on Load Center Style ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00LN74OO2 | | Best Sellers Rank | 991,775 in DIY & Tools ( See Top 100 in DIY & Tools ) 2,803 in Circuit Breakers | | Brand | SIEMENS | | Circuit Breaker Type | GFCI | | Circuit breaker type | GFCI | | Current Rating | 20 Amps | | Current rating | 20 Amps | | Customer Reviews | 4.7 out of 5 stars 763 Reviews | | Global Trade Identification Number | 00887621817329 | | Item Weight | 0.25 Pounds | | Manufacturer | Siemens | | Manufacturer Part Number | Q120DF | | Model Number | Q120DF | | Mounting Type | DIN Rail Mount | | Mounting type | DIN Rail Mount | | Number of Poles | 1 | | Number of poles | 1 | | UPC | 887621817329 | | Unit Count | 1.0 count | | Voltage | 120 Volts | ## Product Details - **Brand:** SIEMENS - **Circuit breaker type:** GFCI - **Current rating:** 20 Amps - **Mounting type:** DIN Rail Mount - **Number of poles:** 1 ## Images ![Siemens Q120DF 20-Amp Afci/Gfci Dual Function Circuit Breaker, Plug on Load Center Style by Siemens - Image 1](https://m.media-amazon.com/images/I/81agrKK9zNL.jpg) ![Siemens Q120DF 20-Amp Afci/Gfci Dual Function Circuit Breaker, Plug on Load Center Style by Siemens - Image 2](https://m.media-amazon.com/images/I/71NNI7kWIkL.jpg) ![Siemens Q120DF 20-Amp Afci/Gfci Dual Function Circuit Breaker, Plug on Load Center Style by Siemens - Image 3](https://m.media-amazon.com/images/I/81JFEp6-QOL.jpg) ![Siemens Q120DF 20-Amp Afci/Gfci Dual Function Circuit Breaker, Plug on Load Center Style by Siemens - Image 4](https://m.media-amazon.com/images/I/51sNhD-68zL.jpg) ## Questions & Answers **Q: Does this fit a Siemens P4040B1200CU load center.** A: Yes it does **Q: With a sub-panel: are there any issues around using 3 wire (2 hot & commom (white))?** A: This breaker is an one pole single circuit. The black wire is attached to the breaker - the white wire is attached to the neutral buss and the bare wire is attached to the ground buss. A sub panel requires when installing four wires -one red (hot 1) one black wire (hot 2) one white (neutral bus) and one bare (ground buss) If not wired by code it will not pass inspection and will probably trip.(NOT WORK) **Q: Will this AFCI/GFCI breaker detect both series and parallel arc faults?** A: Yes, it is Combination type AFCI. Also Class A GFCI, in one breaker. **Q: Will this breaker fit a Siemens ITE series C load center, Cat # G3030MB1200CU? Does it ship in 1-2 days or months? It says months on the below the** A: This is a QFGA2 circuit breaker. You'll need to check the label on your load center to see if it accepts QF breakersI don't know what's with Amazon, I asked about the 1 to 3 month thing also, and they sent me an email saying that their customers didn't know!! Where do you ask the seller a question? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic breaker - Easy replacement for Murray breakers *by S***. on 8 July 2025* Perfect replacement for my Murray circuit breakers.

This one job was insane with false trips. Checked everything. Heard from another electrician the AFCI/GFCI breaker combo wasn't having the issues. Swapped one in and solved the issue. BUT, I also noted the one I took out was really easy to remove. Had almost no friction. The new one went in with force. I began to wonder if the arc was where the breaker was seating into the panel and not the afci/gfci combo as much as a badly made afci breaker ## Frequently Bought Together - SIEMENS Q120DF 20-Amp Afci/Gfci Dual Function Circuit Breaker, Plug-in Load Center Style - Siemens Q115DF 15-Amp Afci/Gfci Dual Function Circuit Breaker, Plug on Load Center Style - Siemens QA120AFC 20-Amp Single Pole 120-volt Plug-On Combination AFCI Breaker --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/282179257-siemens-q120df-20-amp-afci-gfci-dual-function-circuit-breaker](https://www.desertcart.tn/products/282179257-siemens-q120df-20-amp-afci-gfci-dual-function-circuit-breaker) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-03*
