Product FAQs

6 answers
What panelboards are compatible with the Eaton QBGFEP1040?

This breaker installs into Eaton Pow-R-Line panelboards that accept BAB frame bolt-on circuit breakers.

What is the ground fault trip sensitivity for the QBGFEP1040?

This Ground Fault Equipment Protection (GFEP) breaker features a 30mA trip sensitivity. It is designed to protect equipment like heat trace cables and industrial machinery from line-to-ground faults without nuisance tripping.

Can I use the QBGFEP1040 for personnel safety applications?

No. This is a GFEP breaker with a 30mA trip threshold intended strictly for equipment protection. Personnel safety applications require a Class A GFCI breaker with a 5mA trip threshold.

How is the neutral connection wired on this GFEP breaker?

The QBGFEP1040 includes a pigtail neutral wire that must be routed and connected directly to the panelboard neutral bar to power the internal ground fault sensing circuitry.

Does this 1-pole breaker require a load neutral connection?

Yes. To properly monitor for ground faults, the neutral wire from the protected load must be terminated at the breaker load neutral lug, while the breaker pigtail connects to the panel neutral.

Is the QBGFEP1040 a direct replacement for older Cutler-Hammer breakers?

Yes, Eaton and Cutler-Hammer are the same brand. The QBGFEP1040 replaces older Cutler-Hammer breakers that share the exact same catalog number.
