The Square D by Schneider Electric QO 20 Amp Single-Pole Plug-on Neutral 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. Designed for reliability, the QO Plug-on Neutral CAFI Circuit Breaker connects directly to the neutral bar, providing a time and labor-saving installation. QO Plug-on Neutral provides several advantages and among them is fewer connections which lead to faster installation and an innovative neutral jaw eliminates pigtails which in turn frees gutter space. 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. QO circuit breakers have features no other manufacturer can offer. 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.

Rated 3 out of 5 by 2 reviewers.
Rated 1 out of 5 by Beware, this only fits in some QO panels not all! This breaker doesn't have the neutral pigtail. It only fits in some Square D QO panels not all. I have been an electrician for 30 years and will not let my employees buy these. We will only purchase the arc faults with the neutral pigtail because they will fit in all square D QO panels. In some of the QO panels you will have to relocate your breakers because it will only fit in certain spaces also. November 23, 2014
Rated 5 out of 5 by No more neutral pigtales Faster, easier panel installations. Wish Square D/Schnieder would make a GFI and Arc fault combo October 16, 2013
