Built for heavy-duty 240V applications, this 20A double-pole breaker incorporates a 30mA ground fault sensor to defend dedicated equipment against electrical damage. It is ideal for commercial refrigeration, pumps, and specialized heating systems requiring GFEP standards. The unit snaps securely into GE PowerMark Gold, A-Series panelboards, and ABB ReliaHome load centers. Featuring a factory-attached pigtail neutral, it ensures reliable common-trip operation with a 10kAIC rating.

Product FAQs
6 answers
Is the THQL2120GFEP compatible with both GE and ABB panels?
Yes. Following ABB's acquisition of GE Industrial Solutions, this Q-Line breaker is compatible with legacy GE PowerMark Gold load centers and A-Series panelboards, as well as current ABB ReliaHome load centers.
Can this breaker be used in older GE load centers?
Yes, the THQL frame is the standard 1-inch per pole Q-Line breaker format. It is backward compatible with most legacy GE load centers that accept THQL plug-in breakers.
What is the ground fault trip threshold for this GFEP breaker?
The THQL2120GFEP provides Ground Fault Equipment Protection (GFEP) with a 30mA trip threshold. It is designed to protect equipment from damage while preventing nuisance tripping, unlike Class A GFCI breakers which trip at 5mA for personnel protection.
What applications typically require a 30mA GFEP breaker like the THQL2120GFEP?
GFEP breakers are commonly installed for fixed outdoor de-icing and snow-melting equipment, as well as heat trace cables, where a standard 5mA GFCI would be prone to nuisance tripping from normal equipment leakage current.
How is the neutral connection wired on the THQL2120GFEP?
This breaker features a pigtail neutral connection. The coiled white pigtail wire must be connected directly to the panel's neutral bus bar for the ground fault protection circuitry to function correctly.
What is the difference between the THQL2120GFEP and the THQL2120GFT?
The THQL2120GFEP is a Ground Fault Equipment Protection (GFEP) breaker with a 30mA trip level, typically used for heat trace or snow melting equipment. The THQL2120GFT is a Class A Ground Fault Circuit Interrupter (GFCI) with a 5mA trip level designed for personnel protection.
