Product FAQs
8 answersCan I install this CH120 breaker in an Eaton BR series load center?
No. Eaton CH series breakers have a 3/4-inch width per pole and mount exclusively in Eaton or Cutler-Hammer Type CH load centers. Eaton BR panels require 1-inch wide BR series breakers.
Is the Eaton CH120 the same as the Cutler-Hammer CH120?
Yes. Eaton acquired Cutler-Hammer, and the CH120 catalog number remains identical. An Eaton CH120 is a direct, drop-in replacement for an older Cutler-Hammer CH120 breaker.
Is this breaker suitable for switching lighting circuits?
Yes. The 20A CH120 is SWD (Switch Duty) rated, meaning it is certified for regularly switching 120V fluorescent lighting loads without damaging the internal contacts.
Is the CH120 breaker HACR rated for HVAC equipment?
Yes. It carries a Heating, Air Conditioning, and Refrigeration (HACR) rating, making it compliant for protecting multi-motor HVAC circuits that require an HACR-rated breaker.
How much panel space does the CH120 require?
This single-pole breaker requires exactly one 3/4-inch space in a Type CH load center, allowing for a higher density of branch circuits compared to standard 1-inch panels.
Can I land two wires under the terminal lug of a CH120 breaker?
Yes. The box lug on the CH120 is approved to accept two 14 to 10 AWG copper or aluminum wires, or one 14 to 8 AWG wire.
What is the difference between the CH120 and CHF120 breakers?
The CHF120 is an upgraded version of the CH120 that includes a visual trip indicator flag. Both are 20A, single-pole breakers with a 3/4-inch width and are fully interchangeable in Type CH panels.
What are the primary visual identifiers for a Type CH breaker?
Type CH breakers feature a 3/4-inch per-pole footprint and distinctive Sandalwood (tan) toggle handles. This narrower width and specific handle color distinguish them from standard 1-inch black-handled breakers.

- 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!
