Description
Built for residential safety, the Eaton CHCAF120 delivers combination arc-fault protection to mitigate electrical fire hazards. This 1-pole, 20A miniature circuit breaker installs into Type CH load centers and utilizes a standard pigtail neutral connection. Rated at 10 kAIC for 120/240V systems, it provides both long-time and instantaneous trip functions. Note that this legacy model has been replaced by the CHFCAF120, but remains a direct fit for existing CH panelboards requiring AFCI upgrades.Specifications

Product FAQs
6 answersWhich electrical panels are compatible with the CHCAF120?
This breaker is designed exclusively for Eaton Type CH load centers. It will not fit in Eaton BR panels or load centers from other manufacturers.
Does this breaker use a pigtail or plug-on neutral connection?
The CHCAF120 features a standard pigtail neutral. The coiled white wire must be connected directly to the neutral bus bar in your load center for the arc-fault protection to function properly.
How many wires can be terminated in the CHCAF120 box lug?
The box lug can accept either a single 14-8 AWG wire or two 14-10 AWG wires. Both copper and aluminum conductors are supported.
What type of arc-fault protection does the CHCAF120 provide?
This breaker is a combination arc-fault circuit interrupter (CAFCI). It is designed to detect and mitigate electrical fire hazards caused by both parallel and series arcing faults in residential wiring.
Is there a newer replacement model for the CHCAF120?
Yes, Eaton has updated this legacy model to the CHFCAF120. The newer CHFCAF120 serves as a direct replacement for existing CH panelboards requiring AFCI upgrades and includes LED diagnostic indicators to help troubleshoot trip codes.
What trip technology does the CHCAF120 utilize?
It uses thermal-magnetic trip technology, providing both long-time response for overloads and instantaneous response for short circuits.

- 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!
