Product FAQs
5 answersHow many panel spaces does the CH3090 require?
This 3-pole breaker requires three 3/4-inch spaces in a compatible Eaton CH loadcenter.
Can I install the CH3090 in a single-phase panel?
No. Because it is a 3-pole breaker, the CH3090 must be installed in a 3-phase Eaton CH loadcenter.
Is the Eaton CH3090 HACR rated?
Yes, this breaker is HACR rated, making it suitable for heating, air conditioning, and refrigeration motor loads.
Is the Eaton CH3090 interchangeable with Cutler-Hammer or Challenger versions?
Yes. Eaton acquired Cutler-Hammer and Challenger. The CH3090 is the exact same component across these legacy brand names and is fully interchangeable in Type CH panels.
Does the CH3090 feature a common trip mechanism?
Yes, this breaker features an internal common trip connection. If a fault is detected on any single pole, all three poles will open simultaneously to disconnect power safely.

- 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!
