Product Overview

The Square D by Schneider Electric QO 15 Amp Single-Pole Combination Arc-Fault Circuit Interrupting (CAFCI) Circuit Breaker is for use to help protect your wires from arcing faults and is intended for overload and short-circuits protection of your electrical system. Now standard in all Square D brand CAFCI circuit breakers, Time-Saver Diagnostics provide advanced trip indication technology, helping identify the type of fault that has occurred faster. Time-Saver Diagnostics helps take away the guess work and provides diagnostic assistance by identifying the type of fault that last occurred. It saves money by reducing troubleshooting time, simple to use, accurate and reliable. On top of that, all QO circuit breakers are equipped with the exclusive Visit-Trip indicator. When a QO Visit-Trip circuit breaker trips, the handle snaps to a midpoint position between OFF/ON and a highly visible, red indicator easily identifies the tripped breaker. This enables you to easily distinguish which breaker has tripped in a load center that may contain up to 42 different circuit breakers. QO circuit breakers have features no other manufacturer can offer. They come in many different sizes and can meet the needs of virtually every function in your home or business. These types of quality, industry exclusive products keep the Square D brand ahead of the competition and are builders' and electrical contractors' first choice in electrical protection.

Yes, the pigtail is necessary for the QO115CAFIC combination Arc Fault breaker. It is needed to monitor the neutral current, if not hooked up you will get nusance tripping.

Square D Model # QO115CAFIC

So if this is a QO115CAFIC 15amp breaker, in your display picture why does the white paper label on the front of breaker have printed on it "QO120CAFI", but 15 on the switch itself? QO120CAFI is the 20amp breaker! What's the story? Seems dangerous
Asked by: paulbunyan
Well, I would assume someone photo shopped the breaker with 15 on the handle and forgot to change the label part number. You can tell as the 15 on the handle is vertical while it should be on a slight angle. Square D breakers do not have different amperages on the handle and label.

Customer Reviews

QO 15 Amp Single-Pole CAFCI Circuit Breaker is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Upgrade to improve family's safety Great price for an easy upgrade for improved safety. If you're handy and are careful and aware around open circuit panel, can add this ARC fault breaker in 10 minutes. Nice added feature allows you to determine the actual cause of the fault.

Rated 5 out of 5 by from Worked great and saved me $$$ I never changed a breaker before, but this was very simple. I was actually surprised that HD carried this, so I brought it home, took the old one out and popped this one in. The wire is long enough to reach where you need it to go, and the test button worked like it needed to. All in all, Home depot saved me about $100 if not more by not needing an electrician to come out. Thanks for carrying this in the store!!
