Description
1-Pole 20A GFCI Plug-In Circuit Breaker
ABB THQL1120GFT2 and THQL1120PGFT Q-Line GFCI circuit breakers provide 20 amp, 1-pole ground-fault protection for residential and light commercial load center applications.
This listing includes both standard pigtail-neutral and plug-on-neutral GFCI breaker options, allowing selection based on panel compatibility and installation requirements.
Which Version Do You Need?
These breakers provide the same GFCI protection—the main difference is how each model connects to neutral.
- THQL1120GFT2: Standard pigtail-neutral GFCI breaker with a white neutral wire that connects to the panel neutral bar. Best for standard compatible ABB / GE-style load centers.
- THQL1120PGFT: Plug-on-neutral GFCI breaker with no neutral pigtail. Installs directly onto the neutral rail in compatible plug-on-neutral load centers for a cleaner installation.
Key Features

- 10 kAIC interrupting rating
- Q-Line THQL plug-in breaker design
- Ground-fault circuit interrupter protection
- Thermal-magnetic trip protection
- Quick-make / quick-break mechanism
- Easy-to-spot trip indication
- THQL1120GFT2: standard GFCI style with neutral pigtail

Typical Applications
Ideal for branch circuit protection where GFCI protection is required, including kitchens, bathrooms, garages, basements, laundry areas, workshops, and other residential or light commercial circuits.
Product Details
Q-Line breakers are compact plug-in circuit breakers designed for use in compatible ABB / GE-style load centers.
The GFCI function helps detect ground-fault current leakage and interrupt power quickly to reduce shock hazard.
The plug-on-neutral THQL1120PGFT version eliminates the neutral pigtail connection when installed in compatible plug-on-neutral panels.
Important Notes
THQL1120PGFT requires a compatible plug-on-neutral load center; THQL1120GFT2 is intended for standard neutral-bar wiring.
Installation should be performed according to applicable electrical codes and manufacturer instructions.
