Product Overview

The Dual Function Circuit Breaker combines GFCI and AFCI, protecting against both Arc Faults and Ground Faults. This, along with the new Self-Test and 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 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 and 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.

While the product overview lists this item as model Q120DFP, the Siemens website lists model Q120DF as the dual function 20A AFCI/GFCI circuit breaker (@ 10kAIC).

Answer: 
Actual circuit breaker package I received states catalog number Q120DFP, type QFGA2. Back of package states 10kA IC, 120V, wire range #14-8 AWG. So this is a 10,000 and not 22,000 or 65,000 rated breaker.

Hi kwg101,
If your dual function circuit breaker tripped to prevent any arc fault or ground fault conditions then you should be able to reset the breaker. However, with the self test and lockout feature this breaker is constantly running tests on itself to ensure it has not been compromised in anyway. If for any reason the breaker has been compromised it will trip itself and lockout the ability to be turned back on. You may want to have an electrician look at your breaker and see if it needs to be replaced. Read Less

Customer Reviews

20 Amp AFCI/GFCI Dual Function Circuit Breaker is rated 4.0 out of 5 by 4.
Rated 5 out of 5 by from Easy to install, performs as advertised. Purchased to replace a questionable and possibly weak, 30+ year old GFI breaker that tripped too often without reason. Instructions were clear. This breaker has 3 connecting wires: power, neutral and ground. Only difference was having to disconnect the neutral wire from the panel and connect that wire to the new breaker. Everything done within 10 minutes and now outdoor receptacles are both arc fault and ground fault protected making it conform with the current electrical code.

Rated 1 out of 5 by from Frequent false trips. Installed 14 of these in my new home. I get false trips frequently. When I run my on-demand hot water heater I get trips on other circuits. These circuits are way too sensitive. Don't buy these. Buy AF only and put the ground fault at the outlet.
Date published: 2015-07-25
Rated 5 out of 5 by from Safety Enhancing Dual Function Breaker This circuit breaker is a must for all 120 VAC circuits. Protects against overloads, arc faults (series and parallel) and ground faults. Capable of saving property and lives. Every load center should be retrofitted with them.
Date published: 2015-11-11
Rated 5 out of 5 by from Easy to repalce existing ARC Fault I was replacing a 15Amp Arc Fault in my computer room that kept tripping anytime I turn on my computer. Since the new computer needed a 20Amps breaker for the 1000 Watt power supply. It was easy to replace the existing AFCI with the Siemens 20Amp AFCI/GFCI, which protects against fire and shock. I believe I'll replace the other AFCI I have with the AFCI/GFCI version in my home.
