Product FAQs
8 answersWhich load centers are compatible with the CH240GF?
The CH240GF is designed exclusively for Eaton and Cutler-Hammer Type CH load centers. It requires two 3/4-inch spaces and will not fit in Type BR panels or load centers from other manufacturers.
How much panel space is required to install the CH240GF?
Because it is a 2-pole Type CH breaker, it requires two adjacent 3/4-inch spaces on the load center bus.
How is the neutral connected on the CH240GF breaker?
This breaker utilizes a pigtail neutral connection. The attached coiled white wire must be routed and secured directly to the neutral bus bar in the panel for the ground fault circuitry to function correctly.
What wire gauge is supported by the CH240GF terminals?
The box lug terminals on this breaker accommodate copper or aluminum conductors ranging from 14 AWG to 6 AWG.
Can the CH240GF be used on multi-wire branch circuits?
Yes, as a 2-pole 120/240VAC breaker, it can be used to protect 240V loads or 120/240V multi-wire branch circuits that share a single neutral conductor.
What is the ground fault trip threshold for the CH240GF?
This breaker provides Class A ground fault protection, meaning it is calibrated to trip when it detects a ground fault current of 5mA. This level of protection is designed specifically for personnel safety.
Does the CH240GF offer combination arc fault protection?
No, the CH240GF provides only ground fault (GFCI) and standard thermal-magnetic overcurrent protection. It does not include arc fault (AFCI) detection.
Are there alternate catalog numbers for the CH240GF?
Yes, depending on the packaging or specific generation, this breaker is frequently cross-referenced as CHN240GF or CH240GFT.

- 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!
