Schneider Electric QO120CAFIC Arc Fault Circuit Breaker

The Schneider Electric Square D QO120CAFIC is a 20-amp, 120-volt single-pole arc-fault circuit interrupter (AFCI) breaker designed for use in QO plug-in panels. As a combination arc fault device (CAFIC), it detects and interrupts arcing events on a branch circuit to help prevent electrical fires, while still providing standard overcurrent protection for short circuits and overloads. The unit features a plug-in QO form factor with a neutral pigtail and carries a 10,000-ampere interrupting capacity (10 kAIC), suitable for typical residential feeder and branch circuits. It is rated for 1-pole operation on 120 VAC circuits and is Trade Agreement Act (TAA) compliant, making it suitable for government or institutional procurement. Compatible with standard QO load centers, this 20A AFCI breaker is intended for circuits where arc-fault protection is required in living areas, bedrooms, and other incidental loads where electrical fires are a concern.
