Description
Engineered for residential applications, the Eaton CHGF120 provides reliable 5mA ground-fault protection for 120/240V circuits. This 20A miniature circuit breaker utilizes thermal-magnetic technology to detect overloads while monitoring for dangerous ground faults. Designed for 3/4-inch spaces, it mounts into Eaton CH load centers. This legacy model is replaced by the CHFN120GF. The unit features a 10kAIC rating, self-test function, and visual trip flag for easy diagnostics.Specifications

Product FAQs
6 answersWhat load centers are compatible with the Eaton CHGF120 circuit breaker?
This breaker is designed exclusively for use in Eaton Type CH load centers. It requires a 3/4-inch space per pole and is not compatible with Eaton BR or other manufacturer panels.
Does the CHGF120 require a pigtail neutral connection?
Yes, this breaker features a pigtail neutral. You must connect the attached white pigtail wire directly to the neutral bus bar in your load center for the ground-fault protection to function properly.
What is the ground-fault trip threshold for the CHGF120?
This is a Class A GFCI breaker, meaning it is designed to trip when it detects a ground-fault current of 5mA. This provides personnel protection against electrical shock in wet areas like kitchens and bathrooms.
What is the difference between the CHGF120 and CHFGF120 catalog numbers?
The CHFGF120 is the updated version of the CHGF120. The F in the CHFGF120 part number indicates the addition of a mechanical trip flag, which provides a clear visual indication when the breaker has tripped. Both models offer the same ground-fault protection and fit the same Type CH panels.
Does the CHGF120 feature a self-test function?
Yes, modern Eaton GFCI breakers perform routine self-tests to ensure the ground-fault detection circuitry is working correctly. If the breaker fails the internal self-test, it will automatically trip and prevent power from being restored.
Can I install the CHGF120 in an Eaton plug-on neutral load center?
Yes, but because this is a pigtail neutral breaker, it will not utilize the plug-on neutral bus. You must still route and connect the attached white pigtail wire to the neutral bar in the panel for the ground-fault protection to operate.

- 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!
