Product FAQs
6 answersWhat is the ground fault trip threshold for the QBGFEP2040?
This breaker features a 30 mA ground fault trip sensitivity. It is classified as Ground Fault Equipment Protection (GFEP) to safeguard machinery and heat trace systems, rather than a 5 mA Class A GFCI meant for personnel protection.
Which panelboards accept the QBGFEP2040 breaker?
It is designed for Eaton Pow-R-Line panelboards that accommodate BAB frame bolt-on breakers, including the Pow-R-Line 1a, 2, and 3 series distribution panels.
How is the neutral connection handled on this GFEP breaker?
The QBGFEP2040 includes a pigtail neutral wire. This pigtail must be securely terminated at the panelboard neutral bus to power the internal ground fault detection circuitry.
Is the QBGFEP2040 suitable for heat trace applications?
Yes, the 30 mA equipment protection threshold makes this breaker ideal for heat trace cables and commercial equipment where a standard 5 mA GFCI might experience nuisance tripping.
Are Eaton and Cutler-Hammer QBGFEP2040 breakers interchangeable?
Yes. Eaton acquired Cutler-Hammer, and the QBGFEP2040 catalog number is identical across both brands. They are the exact same breaker and can be used interchangeably in listed panels.
Can I install the QBGFEP2040 in a standard residential load center?
No, this is a bolt-on breaker designed specifically for commercial and industrial Eaton Pow-R-Line panelboards. It will not fit in standard plug-on residential load centers like the BR or CH series.
