Siemens QA115AFC 15-Amp Single Pole AFCI Breaker | 120V Plug-On with LED Trip Indicators

The Siemens QA115AFC 15-Amp single pole combination AFCI breaker is designed for 120-volt electrical panels in homes and light commercial spaces. It guards circuits against arc faults while remaining compact and straightforward to install. The combination AFCI technology targets both high energy parallel arcing and the lower energy series arcing that can occur along wiring, cords, and connected devices.

With plug-on installation and a 15 Amp rating, this breaker helps you protect downstream branch wiring, cord sets, and power supplies without adding GFCI functionality. It integrates neatly into standard panels and can simplify panel management by reducing nuisance trips while offering actionable diagnostics through LED indicators. LED trip indicators appear near the handle for five seconds each time the AFCI is turned on and remain visible for up to 30 days after the last trip to aid troubleshooting.

Key benefits you can expect

• Combination AFCI protection for parallel and series arcing faults on 120-volt circuits
• LED trip indicators near the handle identify the last trip condition at a glance
• Additional wire bend space improves routing and terminations during install
• Same angle for both lugs makes wiring paths cleaner and faster
• Torque rating of 25 lb-in helps achieve reliable seating and connections

Real world use cases

Real world use scenarios include upgrading a panel in a living room with multiple outlets and media devices, or wiring a home office with numerous cords and power adapters. The LED indicators provide quick feedback during testing, while the extra bend space and consistent lug orientation reduce installation effort. The 15-Amp rating suits typical branch circuits, balancing protection with performance for everyday loads.

Notes on safety and compatibility

This device is a combination AFCI breaker only and does not replace or function as a GFCI. Always verify compatibility with your panel model and local electrical codes before installation. For best results, pair with proper panel labeling and routine electrical maintenance.
