Overview
The Siemens QA120AFC is a 20 amp, 120 volt, single-pole Type QAF2 combination arc-fault circuit interrupter for compatible Siemens load centers. It combines thermal-magnetic overcurrent protection with parallel and series arc-fault detection, uses a plug-in connection with a neutral pigtail, and carries a 10 kA interrupting rating.
Key Features
-
Protection: Combination AFCI protection detects both parallel and series arcing faults while the thermal-magnetic mechanism protects against overloads and short circuits.
-
Installation: Plug-in mounting with a factory neutral pigtail; the branch conductor terminates at a box lug.
-
Compatibility: Type QAF2 for Siemens load centers specifically listed for this breaker family.
-
Standards: UL 489 circuit-breaker and UL 1699 arc-fault protection references; HACR and SWD rated.
