Abb THQL1120PGFT2 Ground Fault Breaker 1P 20A

Product Description

The ABB THQL1120PGFT2 is a single-pole ground fault circuit interrupter (GFCI) breaker rated at 20 amps with a 10,000 AIC interrupting capacity and plug-on neutral (PON) design. It provides both overcurrent and ground fault protection in a single device, eliminating the need for a separate GFCI outlet at protected locations. The plug-on neutral connection simplifies installation in compatible load centers by attaching directly to the neutral bar without a pigtail wire. Licensed electricians install this breaker as part of branch circuit protection in residential and light commercial electrical panels.

This breaker is suited for residential and light commercial applications requiring GFCI protection on 120-volt branch circuits. Typical installation scenarios include circuits serving bathrooms, kitchens, garages, outdoor outlets, crawl spaces, and other locations where NEC Article 210 mandates ground fault protection. The plug-on neutral feature is specifically designed for compatible load centers that support PON-style breakers, reducing wiring time and improving reliability of the neutral connection.

Key Features

• Single-pole, 20-amp GFCI breaker with 10,000 AIC interrupting rating
• Plug-on neutral design eliminates pigtail wire for faster, cleaner installation
• Combines overcurrent and ground fault protection in one unit
• Meets NEC requirements for GFCI protection on applicable branch circuits
• Compact form factor fits standard load center breaker slots

Compatibility

Designed as an OEM-style replacement or new-installation GFCI breaker for load centers that accept plug-on neutral single-pole breakers of this form factor. Refer to the load center manufacturer documentation to confirm PON compatibility before installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the main panel before installing or replacing any breaker. The plug-on neutral clip must seat fully on the load center neutral bar before energizing. Do not install in a load center that does not support the plug-on neutral connection style, as an improper neutral connection creates a shock and fire hazard.
