Square D by Schneider Electric Square D - QO115DFC 15 Amp Single-Pole Dual Function (CAFCI and GFCI) Circuit Breaker

I used this breaker to install a dedicated circuit for my refrigerator in my Square D Q0 panel and have no complaints, the breaker was easy to install and works as intended. It was a great price compared to my local hardware stores too.

Arrived on time very high quality and easy to install and going strong

This is a quality name brand product that installed easily without issue. These fault breakers can be very expensive but are required by code in my area when new electrical is installed. I was able to find this breaker at a reasonable price. I am not an electrician but was able to upgrade with this product myself.

Item as advertised!

I have no reason to believe that there is anything wrong with this item, but we have been getting occasional nuisance trips. I suppose it is due to this being a CAFCI, so it has the GFCI rating of 5mA ground fault, while the breaker I had in there before was an AFCI, which is rated at 50mA. I did the swap thinking I was "upgrading", but in the end, the nuisance trips are a bit of a hassle, thus the four stars. It seems that the basis of how/why it trips needs to be adjusted somewhat.

This is a standard QO Dual Function Breaker. It works exactly as desired. Just make sure you torque it down appropriately and you're good to go.

So much easier to find exactly what you need online than hunting it down in the big box stores, they have limited amounts and varieties randomly in stock. I installed an outlet in a waterproof box in my yard but wanted a circuit breaker in the fuse box instead of the outlet box. Now I am safe and have easy access should it be necessary. Pricing was pretty much equivalent to other sources.

This breaker only fits a Square D QO panel. A very good breaker at a very good price. It shipped very quickly.

The Square D by Schneider Electric QO 15 and 20 Amp Single-Pole Dual Function (CAFCI and GFCI) Circuit Breakers are fantastic! They work MUCH better than first generation Arc Fault breakers which would trip whenever you started a brushed motor (drill, vacuum, etc.). They reportedly have a two second arc fault delay before tripping, and I have not experienced any tripping from equipment of any kind. Combining both the CAFCI and GFCI in one breaker is brilliant. It save substantial cost where both features are required, and gives peace of mind on older house circuits with old wiring. Can also be used for older non-grounded circuits, but do your own homework on this one or consult your electrician. It does provide a non-grounded GFCI circuit, which is also reportedly CAFCI protected as well. There are mixed opinions on non-grounded GFCI circuits, and level of protection it offers, but it does work. If you retrofit with these breakers, and experience tripping, there is likely an neutral issue or a reversed hot and neutral somewhere in your system. For the DIY crowd, get a circuit analyzer such as a Mastech MS5908A (or the more expensive Extech CT70 or Ideal Industries 61-164). Even if one of the inexpensive 3 light plug style indicators says that the circuit is wired correctly, it still may not be. Only a true Circuit Analyzer can find certain issues wiring. Circuit Testers also can check wiring % amperage loss under various loads, voltage drops under load, GFCI trip times and currents, peak voltages, line frequencies (Hz), impedance - live to neutral, neutral to ground voltage, and a host of information that can make trouble shooting SO much easier. It can also give you peace of mind by measuring voltage drops on a circuit are within code (typically 5%), and not overloaded. Circuit Analyzers are really worth having if you do wiring. Back to breakers... PROS: - Regular over current + both CAFCI and GFCI protection (three functions - even though they call them dual function) in one breaker! - Very little cost increase over a CAFCI or GFCI only breaker. - No nuisance tripping as in the past with Arc Fault breakers - Available in 15 and 20 amp versions available CONS: - Cost... these things are EXPENSIVE when you start putting them on each circuit. - Breakers are physically quite long, and may not fit in all slots of a Square D box. I had interference issues with the plastic insulation separators near the neutral bar at the top two slots on each side of the panel. No big deal. - All downstream neutrals must be segregated to that breaker only, and can not be attached as common neutrals with a different breaker. This can cause tripping if old circuit neutrals are wired incorrectly. But please ask your electrician about these details or use a circuit analyzer to test for underlying issues ...

Installed and working

Works no false trips, test as required occasionally. I’m not sold on the 2 pole afci versions though. This is a pigtail version not neutral plug on.
