Product FAQs
6 answersCan I install the CH290 in an Eaton BR or Square D Homeline panel?
No. The CH290 is designed exclusively for Eaton and Cutler-Hammer Type CH load centers. It is not interchangeable with Type BR, Square D Homeline, or other 1-inch breaker formats.
How much panel space does the CH290 require?
This 2-pole breaker requires two 3/4-inch spaces, taking up a total width of 1.5 inches in a Type CH load center.
What is the proper way to torque the lug terminals on the CH290?
Torque requirements can vary based on the specific wire gauge used. Always refer to the specification label printed on the side of the circuit breaker for the exact inch-pound torque values before terminating your 10 to 1/0 AWG copper or aluminum wire.
Is the CH290 suitable for use with HVAC equipment?
Yes, this breaker is HACR rated, making it approved for use with heating, air conditioning, and refrigeration equipment that requires this specific safety listing.
Can the CH290 be used as a back-fed main breaker?
Yes, it can be used as a back-fed main breaker in compatible Type CH panels, but it requires the installation of an Eaton CHPHD hold-down retainer kit to secure it to the bus bar in compliance with the National Electrical Code (NEC).
Is this the same as a Cutler-Hammer CH290?
Yes. Eaton acquired Cutler-Hammer, and the CH series breakers are the exact same product line. They are easily identified by their classic tan handles and 3/4-inch per pole footprint.

- 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!
