Product FAQs
8 answersWhich load centers accept the CHFP120AF circuit breaker?
This breaker is designed exclusively for Eaton CH series Plug-On Neutral load centers. It will not fit standard CH panels that require a pigtail connection or panels from other manufacturers.
Does the CHFP120AF require a pigtail wire for the neutral connection?
No. This is a Plug-On Neutral breaker. It connects directly to the neutral bar in compatible Eaton CH load centers, eliminating the need for a pigtail wire and reducing gutter clutter.
Which legacy Eaton catalog numbers does the CHFP120AF replace?
This model serves as a direct replacement for older Eaton CH plug-on neutral AFCI breakers, including catalog numbers CHFCAF120PN and CH120CAFPN.
What is the difference between the CHFP120AF and the CHFN120AF?
The CHFP120AF features a Plug-On Neutral connection designed for newer Eaton CH panels, while the CHFN120AF includes a standard pigtail wire for the neutral connection in legacy load centers.
How do I identify the cause of a trip on the CHFP120AF?
This breaker features built-in LED diagnostics. After resetting a tripped breaker, the red LED will blink a specific code from one to six flashes to indicate the fault type, such as a series arc, parallel arc, or overvoltage.
What types of faults does this combination AFCI breaker detect?
As a combination arc fault circuit interrupter, it detects both high-current parallel arcs and low-current series arcs to mitigate electrical fire hazards in branch circuits and connected cords.
What wire sizes are accepted by the terminals on this AFCI breaker?
The box lugs accommodate copper or aluminum wiring ranging from 14 AWG to 6 AWG, providing flexibility for various branch circuit installations.
What trip functions are included in the CHFP120AF?
This thermal-magnetic breaker includes Long-Time and Instantaneous trip functions to protect against standard overloads and short circuits, in addition to its arc fault detection capabilities.

- 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!
