Abb thql2120gft Gfci 2 Pole Circuit Breaker 120/240V 20A

Product Description

The ABB thql2120gft is a Q-Line THQL Series GFCI 2-pole plug-in circuit breaker rated for 120/240V service at 20 amps. It provides ground fault circuit interrupter protection combined with standard overcurrent protection in a single device. The breaker installs in compatible plug-in load centers and panels, making it a direct solution for circuits requiring GFCI protection at the panel level rather than at individual outlets or devices. Electricians install this breaker where code requires GFCI protection for entire branch circuits, such as bathroom, kitchen, garage, outdoor, and other wet-location circuits.

This breaker is suited for residential and light commercial electrical panels. A 2-pole configuration handles 120/240V branch circuits, covering applications that include large appliances and dual-voltage equipment requiring ground fault protection. Panel-level GFCI protection via this breaker provides coverage for the entire downstream circuit without requiring GFCI receptacles at every outlet location.

Key Features

• GFCI protection integrated into a standard 2-pole plug-in circuit breaker form factor
• Rated 20 amps at 120/240V for dual-voltage branch circuit applications
• 2-pole design handles both legs of a 240V or split 120/240V circuit
• Plug-in mounting for compatible Q-Line load centers and panels
• Provides panel-level ground fault protection for entire downstream branch circuits

Compatibility

Designed as an OEM-style plug-in replacement for compatible ABB Q-Line and THQL Series load centers and panels accepting 2-pole plug-in circuit breakers.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel completely before removing or installing any breaker. GFCI breakers require proper connection of the neutral pigtail lead to the panel neutral bar to function correctly. After installation, test GFCI function using the built-in test button before returning the circuit to service.
