Overview
The GE THQL1120PAF2 is a 20 A, single-pole Q-Line combination arc-fault circuit interrupter for compatible plug-on-neutral load centers. It protects a 120 V branch on a 120/240 V AC system, combines AFCI sensing with thermal-magnetic overcurrent protection, and has a 10 kA interrupting rating.
Key Features
-
Combination AFCI protection: Detects supported series and parallel arcing conditions while retaining overload and short-circuit protection.
-
Plug-on-neutral installation: Connects directly to compatible neutral hardware without a separate pigtail and uses a load-side box/screw lug.
-
Q-Line compatibility: Use only in manufacturer-listed Q-Line plug-on-neutral load centers accepting THQL1120PAF2.
-
Verified branch rating: 20 A, one pole, 120 V branch use on a 120/240 V system, with 10 kA interrupting capacity.
