Part of the Cutler-Hammer legacy line by Eaton, this 40-amp ground-fault circuit interrupter delivers reliable 5mA personnel protection. It features a pigtail neutral connection and common trip functionality to ensure safety across both poles during a fault event. Designed to mount into standard Type CH load centers, it serves residential applications requiring wet or damp location safety compliance. This specific model has been replaced by the newer self-testing CH240GFT version.Specifications

Product FAQs
6 answersWhat type of electrical panel accepts the CH240GFI breaker?
This breaker is designed exclusively for Eaton and Cutler-Hammer Type CH load centers. It requires two 3/4-inch spaces, taking up a total width of 1.5 inches on the bus bar.
Will this breaker fit in an Eaton BR series load center?
No, Type CH breakers are 3/4-inch wide per pole and have a distinct mounting clip. They are not interchangeable with Eaton Type BR breakers, which are 1-inch wide per pole.
How is the neutral connection wired on this GFCI breaker?
The CH240GFI features a pigtail neutral wire. This coiled white wire must be connected directly to the neutral bus bar in your load center to power the internal ground fault detection circuitry.
Can I use this 40A GFCI breaker for a hot tub or spa installation?
Yes, the CH240GFI is frequently used in spa panels, such as the Eaton CHSPA40, and hot tub disconnects that require a 40-amp, 240-volt circuit with Class A ground fault protection. Always verify the specific amperage requirements of your spa equipment before installation.
What level of ground fault protection does this breaker offer?
It provides Class A ground fault protection, which is designed to trip when a ground fault of 5mA is detected. This level of protection is required by the NEC for personnel safety in wet or damp locations.
Is there a difference between the Eaton CH240GFI and the Cutler-Hammer CH240GFI?
No, they are the exact same product. Eaton acquired Cutler-Hammer and continues to manufacture the Type CH series under the Eaton brand using the same CH240GFI catalog number.

- CSChristine S.Verified BuyerReviewingEaton / Cutler-Hammer CH2100-LONG - 100A 2 Pole Molded Case Circuit BreakerI recommend this productRated 5 out of 5 stars5/18/26Got a great refurbished breaker - saved a $6500 Service Replacement
When our main breaker frizzed out, the option we were presented with was replacing the entire panel and service due to the type and part - no longer produced for replacement parts. It would be a $6500 replacement.
We'll likely have to do it at some point but, for now, the replacement breaker we were able to source from Superbreakers (with a $25 warranty) was $5900 less expensive. installation ran a few hundred dollars and the tech said the part looked to be in excellent condition and was prepped for install as he would have hoped.
Very thankful for SuperBreakers!
