Description
Engineered to meet NEC requirements for damp locations, the Eaton CH220GFI delivers 2-pole, 20A ground fault protection. It provides essential personnel safety by tripping when leakage current exceeds 5mA. This device installs into Cutler-Hammer and Eaton CH load centers using a plug-on connection and a pigtail neutral wire. For newer code compliance, this unit is replaced by the self-testing (CHFN220GF TO SHIP). It features a 10 kAIC interrupt rating at 120/240V and a common trip mechanism.

Product FAQs
7 answersIs this breaker compatible with Eaton BR load centers?
No. Eaton CH series breakers have a 3/4-inch width per pole and are uniquely keyed to fit only CH load centers. BR panels require 1-inch wide breakers and have a different bus configuration.
How is the neutral connected during installation?
The CH220GFI features a pigtail neutral wire that must be routed and connected to the neutral bus bar in the panel. It does not utilize a plug-on neutral (PON) connection clip.
How much physical panel space is required for this breaker?
Because CH series breakers are 3/4-inch wide per pole, this 2-pole breaker requires two standard spaces, taking up 1.5 inches of total bus space.
What is the ground fault trip threshold?
This breaker provides Class A personnel protection and is internally calibrated to trip when a ground fault leakage of 5mA is detected.
Does this breaker also protect against arc faults?
No. This unit is exclusively a Ground Fault Circuit Interrupter (GFCI). It provides ground fault and standard thermal-magnetic overcurrent protection, but it does not offer Arc Fault Circuit Interrupter (AFCI) capabilities.
What type of applications typically require a 2-pole Class A GFCI?
A 240V Class A GFCI is commonly installed to meet NEC personnel protection requirements for equipment in wet or damp locations, such as pool pumps, spa motors, and specific outdoor receptacles.
Is the CH220GFI the same as the CH220GF?
Yes. Eaton uses the part numbers CH220GF and CH220GFI interchangeably in distribution channels and catalogs. Both catalog numbers represent the exact same 20A 2-pole GFCI breaker.

- 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!
