Overview
The Siemens QA115AFCN is a 15 A, 120 V AC, single-pole QAF2N combination arc-fault circuit interrupter for compatible Siemens plug-on-neutral load centers. It combines series- and parallel-arc detection with thermal-magnetic overload and short-circuit protection and has a 10 kA interrupting rating.
Key Features
-
Combination AFCI protection: Detects supported series and parallel arcing conditions while retaining thermal-magnetic overcurrent protection.
-
Plug-on-neutral installation: Connects directly to the neutral rail in a compatible Siemens load center and uses a load-side box/screw lug.
-
Exact QAF2N family: Use only in Siemens equipment whose labeling accepts QA115AFCN/QAF2N breakers.
-
15 A branch rating: Rated 15 A, one pole, 120 V AC, with 10 kA interrupting capacity.
