Siemens QA115AFCN is a 15-amp, 120-volt single-pole arc-fault circuit interrupter (AFCI) with plug-on neutral, part of Siemens’ QA family. It protects residential branch circuits by detecting arcing faults and rapidly interrupting power to reduce fire risk. This 1-pole AFCI has a 10 kA interrupt rating at 120 V and fits in a standard 1-inch-wide module for plug-in installation. The QA115AFCN uses plug-on neutral wiring (no neutral pigtail required), making it a convenient choice for Siemens-compatible panels that support the QA series AFCI.
