Product FAQs
6 answersWhat older Eaton or Cutler-Hammer breakers does the CHFCAF120 replace?
The CHFCAF120 is the direct replacement for the older CH120CAF combination arc fault breakers. It fits standard 3/4-inch Eaton Type CH loadcenters.
Does this breaker use a plug-on neutral or a pigtail connection?
This specific model features a pigtail neutral wire. The white pigtail must be connected directly to the neutral bar in the loadcenter for the arc fault protection to function correctly.
How do I wire the load neutral for this AFCI breaker?
The load neutral wire from your branch circuit must be inserted into the breaker lug positioned under the white dot on the breaker.
What is the purpose of the diagnostic LED on the CHFCAF120?
The built-in diagnostic LED indicates the most recent trip code, and the visual trip flag shows when the breaker has tripped. This helps electricians quickly identify whether the breaker tripped due to an arc fault, overload, or short circuit.
Can I install this breaker in an Eaton BR series panel?
No. The CHFCAF120 is designed exclusively for Eaton Type CH loadcenters, which use a 3/4-inch format. It is not compatible with 1-inch BR series panels.
What type of arc fault protection does this breaker provide?
It is a Combination Arc Fault Circuit Interrupter (CAFCI), meaning it detects both series and parallel arcing faults to meet National Electrical Code (NEC) requirements for residential dwelling areas.

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.
