Product FAQs
5 answersWhat enclosures and mounting plates are compatible with the Eaton QCGFT2040?
This breaker is designed for Eaton Quicklag enclosures and compatible OEM panels. It utilizes a cable-in/cable-out mounting configuration and can be installed using QC series face mounting plates, such as the QC2FP for two-pole applications.
How is the QCGFT2040 wired into the electrical panel?
This feed-thru breaker uses box lugs for both the line and load side connections, accepting 14 to 4 AWG copper or aluminum wire. It also includes a pigtail neutral wire that must be connected directly to the panel neutral bar for the ground fault sensing to operate correctly.
What type of ground fault protection does the QCGFT2040 offer?
It provides Class A personnel protection with a 5mA trip sensitivity to prevent electrical shock in wet or damp locations. The breaker also includes an integrated self-test feature to ensure continuous compliance with NEC requirements.
What are the interrupting capacity and trip functions of this breaker?
The QCGFT2040 has a 10kAIC rating at 120/240VAC. It utilizes a thermal-magnetic trip unit with fixed long-time and instantaneous functions for overcurrent and short-circuit protection, combined with dedicated ground fault sensing.
Can this breaker replace older Cutler-Hammer QCGFT models?
Yes. Eaton acquired Cutler-Hammer, and the QCGFT2040 serves as an exact, direct replacement for older Cutler-Hammer breakers bearing the same catalog number.
