Description
Engineered for Eaton Type CH load centers, this 40-amp, two-pole breaker provides essential personnel protection against electrical shock. It features advanced self-test technology that periodically conducts an internal diagnostic routine to ensure continuous reliability. Serving as a seamless upgrade for the older CH240GF model, it utilizes a standard plug-on mounting style. The 10kAIC rating and common trip mechanism make it suitable for demanding residential and commercial applications.Specifications

Product FAQs
4 answersCan I install the CH240GFT in an Eaton Type BR or competitor panel?
No. The CH240GFT features a 3/4-inch plug-on mounting design that is strictly compatible with Eaton Type CH load centers. It will not fit in Type BR panels or load centers from other manufacturers.
What is the difference between the CH240GFT and the older CH240GF?
The CH240GFT is the direct replacement for the discontinued CH240GF and CHN240GF models. The "T" in the catalog number indicates the addition of automatic self-test technology, which periodically runs internal diagnostics to ensure the ground fault circuitry remains compliant with current NEC standards.
How is the neutral connected on the CH240GFT?
This breaker utilizes a standard pigtail neutral. The attached white wire must be routed and terminated directly to the neutral bus bar in the panel. It is not a plug-on neutral (PON) design.
What level of ground fault protection does the CH240GFT offer?
It provides Class A, 5mA ground fault protection for personnel, alongside standard thermal-magnetic overcurrent defense. The breaker will trip if it detects a ground fault leakage of 5mA or greater.

- 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!
