Product FAQs
6 answersWhat is the direct replacement for the obsolete Cutler-Hammer CHH3225 circuit breaker?
The Eaton CVH3225X is the exact, manufacturer-approved replacement for the discontinued CHH3225 3-pole, 225A main breaker.
Which Eaton meter stacks is the CVH3225X designed to fit?
This breaker is designed for use as a tenant main in Eaton 35MM and 37MM commercial modular metering stacks.
What does the X suffix in the CVH3225X catalog number indicate?
The X suffix indicates the breaker comes equipped with load-side lugs only, which accept up to 4/0 AWG wire. The line side is designed to bolt directly to the meter stack bus without standard wire terminals.
Do I need a separate mounting hardware kit to install this breaker?
When installing the CVH3225X in 35MM or 37MM modular metering stacks, no additional mounting hardware is required. However, if you are installing it in 1MP, 1MM, or 3MM residential stacks, you will need the 1MMCBK mounting kit, or you must order the breaker with the MM suffix.
Can I use wire larger than 4/0 AWG with this breaker?
The standard load lugs on the CVH3225X accept up to 4/0 AWG wire. If your application requires larger conductors up to 300 kcmil, you must install the optional 3TA225CVK lug kit.
What is the difference between the CV3225X, CVS3225X, and CVH3225X?
These breakers share the same physical frame and 225A rating but have different short-circuit interrupting capacities. The CVS is rated at 42kAIC, the CV is rated at 65kAIC, and the CVH provides the highest rating at 100kAIC at 240V.
