Product FAQs
5 answersWhat is the ground fault trip threshold for the CHFN120EP?
This breaker features a 30mA ground fault trip threshold. It is designed for equipment protection, also known as GFEP, rather than the 5mA threshold used for Class A personnel protection.
Can I use the CHFN120EP to replace older Eaton or Cutler-Hammer GFEP breakers?
Yes, the CHFN120EP serves as the direct replacement for discontinued models such as the CHFEP120 and CH120EP.
What type of electrical panel is required for this breaker?
The CHFN120EP is designed exclusively for Eaton CH series load centers, which utilize a 3/4-inch pole spacing. It will not fit BR series or other 1-inch load centers.
How does the neutral connection work on this breaker?
This model features a pigtail neutral wire that must be connected directly to the neutral bus bar in your load center to ensure proper ground fault detection.
Is this breaker suitable for protecting bathroom or kitchen receptacles?
No. Because it has a 30mA trip threshold for equipment protection, it does not meet the 5mA Class A GFCI requirements for personnel protection in wet areas. It is typically used for heat tracing, snow melting equipment, or dedicated machinery.
