Product Overview

  • Provides Dual protection: Arc Fault and GFCI in one device
  • Built in Time Saver Diagnostics allows easier troubleshooting
  • Compatible with Square D QO electrical panels, CSED with 1 Space
Square D by Schneider Electric QO 20 Amp 1-pole Dual Function Circuit Breakers is a space and labor saving device, engineered to meet prevailing NEC requirements. This device combine two critical technologies; Combination Arc Fault protection and Ground Fault protection (class A), in a single, easy-to-install device. The NEC now requires both Combination Arc Fault and Ground Fault protection on all 1-Pole, 15 Amp and 20 Amp kitchen and laundry circuits. Prior to the release of this new device, a contractor or homeowner's only choice would have been to use a Combination Arc Fault circuit breaker in conjunction with an expensive, bulky Ground Fault receptacle. The new Dual Function circuit breakers help reduce cost and eliminate the hassle of using two separate devices to provide this essential protection. It's a win for contractors and homeowners alike. Like all Square D CAFI Circuit Breakers, it is integrated with time saver Diagnostics, a unique feature that provides additional circuit information and minimizes troubleshooting at the touch of a button.

Questions & Answers

Can I use this breaker in a homeline box

Asked by: Chris
No, QO series electrical equipment is a higher quality than HomeLine series panels. This will only fit a QO panel that is not bolt in.

pictures of dual function show rear mount clip close to center vs single function appears approx 1/3 from botton??
Asked by: dan
Dan, that is because the AFCI - GFCI QO type breaker is longer than the others. QO style breakers will only fit a QO panel.

I currently own a service panel where this breaker will be the solution, but in the future I will need to modernize my panel and all the SquareD Q0 service panels are now plug on neutral. Will I be able to re-use these breakers on the new panel or would I need to buy the QO120PDFC (same breaker but for plug on neutral panels) ? Thank you
Asked by: Smith
These should work on a new or old panel. It is the old panels that will not accept the breakers with the plug in neutral. The new panels have a neutral bar that runs the FULL LENGTH of the box and the screws are in pairs with a space for the breaker to snap on. The old box neutral bars have a continuous row of tightly spaced screws. They DO NOT RUN THE FULL LENGTH OF THE BOX.

QO 20 Amp Single-Pole Dual Function (CAFCI and GFCI) Circuit Breaker is rated 4.5 out of 5 by 8.

With the changes in the 2017 NEC this is now a required items to be installed for any upgrade or all new installations. This is a Sqaure D product, that is the best that money can buy for the safety of your Electrical System. This product is much better than the outlets that one can install. This product also covers Arc Fault issues that may occur. I would never allow a cheaper product to put my families lives in danger of an electrical failure, or a fire. I follow a practice of, "Do the Job Right the First Time, using the Best Hardware that you can get, and you will Never have to worry with it again". I will never use anything other that Square D Electrical Equipment. Period.

Rated 1 out of 5 by from Unreliable. Had my entire home rewired by a professional, licensed electrical contractor. New breaker box too. They did a GREAT job. Inspectors came in... passed everything with flying colors. Couldn't stop commenting on the quality of work that was done. Once completed, however, these installed breakers will trip from time to time for no apparent reason. In a bad week, I'd have to reset up to a dozen of them. A good week? Maybe 4-6. My electrician was at a loss. We contacted the manufacturer and they told my electrician that they were 'aware' of the sensitivity issues with these breakers. They claim they'll trip if the utility company is doing any work on lines in the area, that any surges the work creates can cause them to trip. The company (Schneider Electric) claims they're working on a solution for existing breakers and to implement that in future manufacturing. I guess I have to live with this? Today a breaker tied to one of my computers tripped and I lost a days worth of work. Completely unacceptable. My electrician is offering to replace them all with more reliable breakers, but he shouldn't have to foot the bill or invest more time in this issue. These breakers are totally unreliable, and frustrating to say the least. If you like to have to constantly reset your breakers, by all means, buy these. But if you want something reliable, look elsewhere.

Rated 5 out of 5 by from Great product. My concern is that the stores don't carry these because of the new no neutral whip... Great product. My concern is that the stores don't carry these because of the new no neutral whip style for the new products Square D puts out now. The corporate people who make these decisions to not carry this style is outrageous. Do they know how many older panels are out there that cannot use the no neutral whip style

Rated 5 out of 5 by from Meets new code requirement These breakers meet the new code requirement that requires both GFCI and AFCI circuit protection in various places in your home. They were easy to install. The Home Depot price was the best around. Wish the item was available at my local store, but they do not. Had to order on line and wait to install.

Rated 5 out of 5 by from CAFI Square D I have considerable confidence in Square D products; nevertheless, it is an act of faith that the CAFI will in fact protect occupants of our home.

Rated 5 out of 5 by from Seems Good This is a new product, not even mentioned in most books on wiring. I decided to take a chance on it because it was just what I was looking for -- ground fault protection as well as arc fault protection. It saved me from having to install ground fault receptacles, and it would also told tell me if I had a loose connection or had wired something wrong. As it turned out, all my connections were good but now I have peace of mind about it. The product also has diagnostics so you can tell what kind of a fault you have. My breakers have been in use for two months now and they are working great. I have tested them during this time and they are doing what they are supposed to do. The price bothered me but it saved me the cost of GFI receptacles so maybe it wasn't so bad.

Rated 5 out of 5 by from Square D 20A Dual function circuit breaker I bought this breaker a few weeks ago, and a few days after installing it, I happened to touch both prongs of a plug on a video console that I was disconnecting. The breaker tripped immediately, and I barely felt anything.
