Product FAQs
6 answersWhat type of electrical panel is required for the CH325 breaker?
This breaker is designed exclusively for Eaton and Cutler-Hammer Type CH 3-phase load centers. It will not fit in BR series, Square D, or other manufacturer panels.
How much panel space does the CH325 require?
As a 3-pole breaker in the CH series, it requires three 3/4-inch spaces, taking up a total of 2.25 inches of width on the bus bar.
Is the CH325 suitable for use with heating, air conditioning, and refrigeration equipment?
Yes, this breaker is HACR rated, making it approved for use with compatible HVAC and refrigeration systems.
Is there a difference between the Eaton CH325 and the Cutler-Hammer CH325?
No. Eaton acquired Cutler-Hammer, and they manufacture the CH series under both names. The CH325 catalog number represents the exact same breaker regardless of which brand name is printed on the label.
Does this breaker feature a common trip mechanism?
Yes, it features an internal common trip mechanism. An overload or short circuit on any single phase will simultaneously trip all three poles, disconnecting power to the entire circuit for safety.
How does the thermal-magnetic trip mechanism operate on the CH325?
The breaker uses fixed long-time and instantaneous (LI) trip functions. The thermal element provides delayed tripping for mild overloads, while the magnetic element reacts instantly 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!
