Part of the CH series, this 3-pole, 25A miniature circuit breaker is engineered for use in Eaton and Cutler-Hammer Type CH load centers. It provides dependable overload and short-circuit protection for commercial and industrial three-phase branch circuits. Featuring a plug-on mounting style, it installs quickly into compatible panelboards and accepts 14-6 AWG copper or aluminum wiring. Rated at 10 kAIC at 240VAC, this breaker includes an internal common trip mechanism and is HACR rated.
What 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.

I am hopeful this fairly new arc monitor circuit breaker idea is going to have a more longevity future. Founder Fred Kiko was an amazing man. Always room for safety inventions.
