Product FAQs
5 answersWhat older Eaton or Cutler-Hammer part numbers does this breaker replace?
The CHFN120AF is the direct manufacturer replacement for legacy CHFCAF120 and CH120CAF combination arc-fault circuit breakers.
Will this breaker fit in an Eaton BR load center?
No. This unit is designed exclusively for Eaton CH series load centers. It requires a 3/4-inch wide space per pole and will not physically seat in a 1-inch BR series panel.
How is the neutral connection made on this AFCI breaker?
This model utilizes a traditional pigtail neutral. The coiled white wire permanently attached to the breaker must be routed and secured directly to the neutral bus bar inside the load center.
What kind of arc-fault protection does this breaker provide?
It functions as a combination arc-fault circuit interrupter (CAFCI). This means it actively monitors the branch circuit to detect both series and parallel arcing faults to help meet modern electrical code requirements.
What is the function of the built-in LED light on this breaker?
The diagnostic LED displays specific blink codes after a trip event. This feature helps electricians quickly determine if the circuit tripped due to an arc fault or a traditional thermal-magnetic overload.

Worked perfect but this breaker is bit of a unicorn and took a while to receive after being ordered. In the end Superbreaker came through at the right price.
