Description
Providing a 30mA trip sensitivity, the Eaton GFEP240 is engineered to safeguard heavy-duty equipment from damaging ground faults. This 40A, two-pole breaker is ideal for applications like well pumps or heat tracing where standard 5mA personnel protection would cause unwanted nuisance tripping. The plug-on breaker installs into Eaton Type BR load centers and utilizes a pigtail neutral. It carries a 10 kAIC interrupt rating at 120/240V.Specifications

Product FAQs
7 answersWhich load centers are compatible with the GFEP240 circuit breaker?
This breaker is designed for Eaton Type BR load centers. It is also approved for use in specified legacy Westinghouse, Challenger, Bryant, and Cutler-Hammer panels that accept Type BR breakers. Always verify the panel label for approved replacement types before installation.
What is the ground fault trip threshold for the GFEP240?
The GFEP240 is a Ground Fault Equipment Protection (GFEP) breaker calibrated to trip at approximately 30mA. It is designed to protect equipment from damaging line-to-ground faults, unlike Class A GFCI breakers which trip at 5mA for personnel protection.
In what applications should a 30mA GFEP breaker be used instead of a 5mA GFCI?
A 30mA GFEP breaker is typically used for heat tracing cables, snow melting equipment, well pumps, and other commercial or industrial loads where a 5mA threshold would cause nuisance tripping, but equipment protection is still required. It does not meet NEC requirements for personnel protection in areas like bathrooms or kitchens.
How is the neutral connection wired on the GFEP240?
This breaker features a pigtail neutral connection. The coiled white pigtail wire must be connected directly to the neutral bus bar in the load center to power the internal ground fault circuitry, while the load neutral connects to the breaker itself.
What wire sizes are accepted by the box lugs on this 40A breaker?
The terminals on the GFEP240 accept copper or aluminum wire ranging from 14 AWG to 4 AWG. Ensure the wire is sized appropriately for the 40A load and tightened to the torque specifications printed on the breaker.
Can I install the GFEP240 in an Eaton Type CH load center?
No. Eaton Type BR and Type CH are separate platforms with different mounting geometries and bus connections. The GFEP240 is a 1-inch wide plug-on breaker and will not fit in a 3/4-inch Type CH panel.
Does the GFEP240 replace older Cutler-Hammer or Bryant GFEP breakers?
Yes, Eaton acquired Cutler-Hammer and Bryant. The GFEP240 is the direct replacement for legacy 40A, 2-pole Type BR ground fault equipment protectors bearing those brand names.
