Siemens QA115AFC NS Arc Fault Circuit Breaker

Siemens QA115AFC NS Arc Fault Circuit Breaker is a 1-pole, 15-amp arc-fault interrupter designed for 120V circuits in Siemens load centers. This combination AFCI provides arc-fault protection to detect and interrupt hazardous arcing conditions, helping prevent electrical fires on residential branch circuits. The plug-in breaker is part of the Siemens QA family and carries a 10,000-amp interrupting rating at 120V, making it suitable for standard home wiring on 15A circuits. A front-face LED indicator signals when the last trip was caused by an arc fault, aiding troubleshooting after a fault. Typical applications include protecting lighting and receptacle circuits in homes and apartments where AFCI protection is required by code, and it fits Siemens Type QA panels and other compatible load centers that accept plug-in breakers.
