Description
Part of the CH family, the Eaton CHFGF120 provides essential 20A ground-fault protection for branch circuits. Equipped with a pigtail neutral, this 1-pole breaker is engineered to detect low-level ground faults and interrupt power before injury can occur. The plug-on design ensures quick compatibility with Eaton Type CH load centers, effectively replacing legacy CH120GF models. With a 10 kAIC rating, the breaker features a highly visible trip flag that alerts users to fault conditions.Specifications

Product FAQs
6 answersWill the Eaton CHFGF120 fit in a standard 1-inch load center?
No, this breaker is specifically designed for Eaton and Cutler-Hammer Type CH load centers, which use a 3/4-inch space per pole. It is not compatible with 1-inch Type BR panels or other brands.
Is the CHFGF120 a direct replacement for the CH120GF?
Yes, the CHFGF120 replaces the discontinued Cutler-Hammer CH120GF. The newer CHF version maintains the same fit and electrical ratings while adding a visual trip indicator flag for easier troubleshooting.
How is the neutral connection handled on the CHFGF120?
This model features a traditional pigtail neutral wire. During installation, the coiled white pigtail must be routed and secured to the panel's neutral bus bar to power the breaker's internal ground fault circuitry.
What type of ground fault protection does this breaker offer?
The CHFGF120 provides Class A personnel protection. It is designed to detect low-level ground faults and interrupt power if the fault current exceeds 5mA, making it suitable for residential areas requiring GFCI protection, such as bathrooms and kitchens.
Does this breaker have a visual trip indicator?
Yes, it features a mechanical trip flag. If the breaker trips due to an overload, short circuit, or ground fault, a red flag appears in the window to help you quickly identify the problem circuit in the panel.
Does the CHFGF120 include an automatic self-test function?
Yes, this GFCI breaker performs periodic self-tests to ensure the ground fault detection circuitry is functioning correctly. This complies with updated UL requirements for continuous personnel protection.

I needed these breakers for an install - first time using the company. They said they had them in stock. Took over a week to fulfil the order and it was 11 or 12 days before I had my hands on them. Tough on my business. Then when I went return them they hit me with so many fees that I was gonna net under $30 on a $104 order. It's too bad this was my first experience with them. I'll be sure to tell my electricians and project managers to never use this company. Short sighted. They won the battle but lost the war with a potential great long term client.
