Siemens Q1515AFCN AFCI Arc Fault Circuit Breaker

The Siemens Q1515AFCN is a 1-pole tandem CAFCI arc-fault circuit breaker that packs two independent 15 A circuits into a single QTAN plug-on-neutral slot. Designed for 120 V AC operation, it carries a 10 kA interrupting rating and is a UL Type QTAN device, meaning it uses a plug-on neutral connection rather than a pigtail lead. The “N” suffix denotes the plug-on neutral variant, while the tandem design allows two circuits to be protected in one physical breaker position, saving space in compatible Siemens panels. Cataloged as Q1515AFCN, it is intended for panel boards that accept QTAN tandem AFCI breakers and provides two 15 A protections within one footprint, facilitating compact installations in residential or light-commercial settings. This tandem AFCI offers arc-fault protection on both circuits without compromising overcurrent protection, making it suitable for branch circuits that require ARC detection per applicable electrical codes, such as living areas and outlets where arc-fault coverage is mandated.
