Product Overview

The Dual Function Circuit Breaker combines Class A 5mA GFCI and Combination Type AFCI, protecting against both Arc Faults and Ground Faults. This, along with the new Self-Test feature, makes it the first in class in electrical safety for homeowners. The 2014 National Electrical Code (NEC) 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 2 devices into once solution that provides both cost savings and less hassle in installation and maintenance. This is a win solution for everyone. Testing GFCI's and AFCI's 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 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. This effortless system guarantees that only the best protection is given to your home at all times.

This is not the 22kA H breaker. I don't know what the P signifies. Siemens does not show a Q120DFP in their latest breaker catalog.

Both the 15 and 20 amp version have a pigtail. The angle of the photo makes it appear there is no pigtail but it is just obscured by the breaker.

If the wiring diagram lists the Type QPF GFCI breaker, yes, there are UL substitution letters that authorize use of the Type QFGA2 dual function breaker, which we can provide. Please send a request to productselection.us@siemens.com.

Compatibility is listed on the cover of any modern panel board. The QA120DF is compatible with PL. I would have to research the ES.

I've already replaced 3 of these POS's with "regular" breakers. Nuisance trips are infuriating! We were standing in the house talking for @ half an hour and I thought I heard a breaker trip. Walked into the laundry room and the AFCI/GFCI breaker for the washing machine tripped and NOTHING was even plugged into it! This was the first time that breaker had tripped (it's been "in service" for @ 6 months). Maybe the "breeze" from the AC tripped it (the AFCI/GFCI breaker the AC is on has also tripped several times)? AC will run for days, then suddenly trip - no idea why. Two other AFCI/GFCI breakers were tripping constantly - for NO reason! I had the electrician check everything and there were NO ISSUES. These things just trip whenever they feel like it. I spent over $600.00 on these useless POS's! Reading online, electricians comment that all this tripping is a good way to rack up labor costs trying to figure out what's going on. They also say they aren't "perfect" and new generations get better and better. Who can afford to keep replacing these things with new ones, given their ludicrous pricing? As one electrician said, they should have been perfected BEFORE they were required by the Code. As far as I'm concerned, AFCI/GFCI breakers were just required by the "Code" in order for the manufacturers to make a bunch more money!
