Description
Built for equipment-level safety, the Eaton CH120EPD is a 20-amp, single-pole ground fault equipment protector (GFEP). It utilizes a 30mA trip threshold to protect heat trace lines, pumps, and industrial machinery from damaging ground faults. Featuring a compact 3/4-inch form factor, this plug-on breaker installs into Eaton CH series load centers. It includes a pigtail neutral wire and is the predecessor to the newer CHFN120EP model.Specifications

Product FAQs
7 answersWill the CH120EPD fit in a standard Eaton BR load center?
No, this breaker is designed exclusively for Eaton Type CH load centers. Type CH breakers have a 3/4-inch width per pole, whereas Type BR panels require breakers with a 1-inch width per pole.
What is the difference between the CH120EPD and a standard GFCI breaker like the CH120GF?
The CH120EPD is a Ground Fault Equipment Protector (GFEP) with a 30mA trip threshold, designed to protect machinery and equipment like heat trace lines or pumps. A standard GFCI breaker, such as the CH120GF, has a 5mA trip threshold and is intended for personnel protection.
How is the neutral connection made for this GFEP breaker?
The CH120EPD features a pigtail neutral wire. During installation, this coiled white wire must be connected directly to the neutral bar in the load center to ensure the ground fault circuitry functions properly.
What is the ground fault trip sensitivity for this breaker?
This equipment protection breaker features a 30mA ground fault trip sensitivity. It is calibrated to prevent damage to equipment rather than providing the 5mA sensitivity required for Class A personnel protection.
Has the CH120EPD been replaced by a newer model?
Yes, the CH120EPD is the predecessor to the newer Eaton CHFN120EP model. Both are 20-amp, single-pole GFEP breakers with a pigtail neutral, but the newer CHFN version includes a trip flag indicator.
Can I use this breaker for a dedicated heat trace circuit?
Yes, the 30mA ground fault equipment protection (GFEP) provided by the CH120EPD is commonly required for heat trace lines, snow-melting equipment, and dedicated industrial pumps to prevent nuisance tripping while protecting the equipment.
Does this breaker require a dedicated neutral wire from the load?
Yes, like most ground fault breakers, the load neutral must be connected directly to the breaker terminal, while the breaker's pigtail wire connects to the panel's neutral bar. This allows the breaker to monitor the current balance between the hot and neutral conductors.

- 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!
