ABB / General Electric THQL2135GFT2 GFCI Miniature Circuit Breaker

The THQL2135GFT2 features a pigtail neutral. The coiled white pigtail wire must be connected directly to the panel's neutral bus bar for the ground fault protection to function properly. The load neutral connects to the breaker's designated load neutral lug.

For straight 240V loads that do not require a neutral, you do not need to connect a wire to the breaker's load neutral lug. However, the breaker's white pigtail must still be connected to the panel's neutral bus bar to power the GFCI mechanism.

This breaker provides Class A 5mA ground fault personnel protection. It includes an internal self-test feature to continuously verify the GFCI circuitry is functioning correctly.

ABB acquired GE Industrial Solutions, so this breaker may arrive with either ABB or GE branding. The product is identical in form, fit, and function regardless of the label.

Yes, the THQL2135GFT2 is the direct modern replacement for the older THQL2135GFT model. It adds continuous self-test capabilities while maintaining the same physical footprint.

THQL breakers require a full 1-inch space per pole. They cannot be installed in half-inch slots designed exclusively for THQP tandem breakers, though many GE PowerMark Gold panels accept both types in designated positions.
