Product FAQs
8 answersWhat type of load center is required for the CH280?
This breaker is designed exclusively for Eaton or Cutler-Hammer Type CH load centers. It features a 3/4-inch per pole width and will not fit in 1-inch Type BR panels.
Can I use this breaker in a Type BR or standard 1-inch load center?
No. The CH280 has a 3/4-inch per pole footprint specific to Type CH panels. It is not interchangeable with 1-inch format breakers like Type BR, HOM, or QP.
How much panel space does the CH280 require?
As a 2-pole Type CH breaker, it requires two 3/4-inch spaces, taking up a total of 1.5 inches of space on the bus bar.
What is the recommended tightening torque for the box lugs on the CH280?
The box lugs on this 80A breaker should be torqued to 65 lb-in. Always verify with the specification label on the breaker or the load center door before finalizing connections.
Does this breaker require a hold-down kit if used as a back-fed main?
Yes. When installed as a back-fed main breaker in a Type CH load center, you must use a hold-down retainer kit, such as the CH125RB, to comply with NEC requirements.
Is the Eaton CH280 the same as a Cutler-Hammer CH280?
Yes. Eaton acquired Cutler-Hammer, and the Type CH product line remains identical. A CH280 breaker branded as Eaton is an exact replacement for an older Cutler-Hammer CH280.
Does the CH280 include GFCI or AFCI protection?
No. This is a standard thermal-magnetic breaker providing overload and short-circuit protection only. It does not include ground fault or arc fault circuitry.
What does the LI trip function on this breaker indicate?
The LI designation means this thermal-magnetic breaker includes both Long-Time and Instantaneous trip functions. The long-time element handles sustained overloads, while the instantaneous element reacts immediately to severe 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!
