Product FAQs
10 answersWhat type of electrical panel is compatible with the CH220CAF?
This breaker is designed exclusively for Eaton CH series load centers. It will not fit in Eaton BR panels or load centers from other manufacturers due to its specific mounting design.
How much panel space does this breaker require?
It requires two 3/4-inch spaces in your load center, which is the standard width for a two-pole CH breaker.
Does this breaker feature a plug-on neutral or a pigtail neutral connection?
The CH220CAF utilizes a standard pigtail neutral wire that must be routed and connected directly to the neutral bus bar in the panel.
What type of arc fault protection does this breaker provide?
It is a combination type AFCI. This means it detects and mitigates both series and parallel arcing faults to help prevent electrical fires in residential wiring.
Can I use this breaker for multi-wire branch circuits?
Yes, because it is a two-pole breaker rated for 120/240V AC, it is suitable for multi-wire branch circuits or dedicated 240V loads that require arc fault protection.
What wire sizes are accepted by the terminals on this breaker?
The box lugs accept copper or aluminum wiring ranging from 14 AWG to 6 AWG, providing flexibility for various circuit requirements.
Is there a plug-on neutral version of this breaker available?
Yes. While this specific model uses a pigtail neutral, Eaton manufactures plug-on neutral equivalents for use in newer CH load centers designed to accept them.
How can I tell why the breaker tripped?
This model includes a built-in LED diagnostic indicator that helps electricians identify whether the trip was caused by a series arc, a parallel arc, or a standard overcurrent event.
What does the 10kAIC rating signify for this breaker?
The 10kAIC interrupting rating indicates the maximum fault current the breaker can safely clear without sustaining damage. This is the standard rating for most residential applications.
Does this breaker have a common trip mechanism?
Yes, it features an internal common trip connection. This ensures that both poles trip simultaneously if a fault is detected on either leg of the circuit, completely disconnecting power to the load.

- 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!
