With its innovative LED trip indicator and compatibility with Siemens load centers, this breaker is the smart choice for modern electrical safety. ## Description Two state-of-the-art technologies packaged in one small device - The Dual Function Circuit Breaker combines GFCI and AFCI, protecting against both Arc Faults and Ground Faults. This, along with the new Self Test & Lockout feature, makes it the first in class in electrical safety for homeowners. The 2014 National Electrical Code (NEC) now requires both Arc Fault and Ground Fault protection on kitchen and laundry circuits. Before the release of Dual Function Circuit Breakers, the only option to comply with this code was to pair an AFCI circuit breaker with a GFCI receptacle. The Dual Function Circuit breaker combines these two devices into one solution that provides both cost savings and less hassle in installation and maintenance. This is a win solution for everyone. A device that tests itself - Testing GFCIs and AFCIs on a monthly basis is a good idea that is sometimes forgotten. Underwriters Laboratories (UL) suggests that AFCI/GFCI devices be tested every 30 days after installation to ensure they are properly working. Now the new Self Test & Lockout feature enables the Dual Function Circuit Breaker to automatically and continuously test itself to ensure that it is working properly. If it is detected that the device has been compromised, the device trips itself and locks out the homeowner from resetting the device, reducing the possibility of the homeowner incorrectly assuming that the device was tripped to prevent a ground/arc fault. This effortless system guarantees that only the best protection is given to your home at all times. ## Features - Faster, more cost effective installation to meet code requirements compared to installing an AFCI breaker and GFI receptacle - Lower cost compared to AFCI breaker and GFCI receptacle - For use on Siemens load centers that accept UL type QFGAH2 breakers - Siemens exclusive LED trip indicator pinpoints cause of trip - HACR, SWD, 120 Volt AC rated ## Images ![Siemens Q120DFH 20-Amp Afci/Gfci Dual Function Circuit Breaker, Plug on Load Center Style - Image 1](https://m.media-amazon.com/images/I/716XSqXnhmL.jpg) ![Siemens Q120DFH 20-Amp Afci/Gfci Dual Function Circuit Breaker, Plug on Load Center Style - Image 2](https://m.media-amazon.com/images/I/71BH5XcsRxL.jpg) ![Siemens Q120DFH 20-Amp Afci/Gfci Dual Function Circuit Breaker, Plug on Load Center Style - Image 3](https://m.media-amazon.com/images/I/51sNhD-68zL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ This is a great break AFCI and GFCI protection built into one unit *by P***M on Reviewed in the United States on March 4, 2015* This is a great break AFCI and GFCI protection built into one unit. Like the indicator, the self-testing functionality, and the built-in testing button. The only issue that I have with this breaker is that if there is an APC UPS on the load, the test button does not function correctly (does not trip circuit breaker), but GFCI protection still works (do not have equipment to test AFCI). Have contacted Siemens about this and appears to be a known issue that they are still exploring.UPDATE Jun-2015: No solution for my APC UPS issue encounters. Told by Siemens tech that it is an APC issue and would need to replace APC UPS or to contact APC to resolve. --- ## 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.sg/products/129893080-siemens-q120dfh-20-amp-afci-gfci-dual-function-circuit-breaker](https://www.desertcart.sg/products/129893080-siemens-q120dfh-20-amp-afci-gfci-dual-function-circuit-breaker) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-11-08*
