Product FAQs
7 answers
Can I use the Eaton CVH3225 to replace an older Westinghouse CCH3225?
Yes. Eaton acquired the Westinghouse distribution equipment line, and the CVH3225 serves as the direct modern replacement for obsolete Westinghouse and Cutler-Hammer CCH3225 and CHH3225 circuit breakers.
What enclosures and meter stacks are compatible with the CVH3225?
This breaker is designed for installation in Eaton Type ECC unit enclosures. It is also widely used as a tenant main breaker in Eaton 35MM and 37MM group metering stacks.
What wire sizes and materials are accepted by the terminals on this breaker?
The factory-installed lugs accept both copper and aluminum conductors ranging from 6 AWG to 4/0 AWG. Ensure proper torque specifications are followed during installation.
Is the CVH3225 suitable for high fault current environments?
Yes. With a 100kAIC interrupting rating at 240VAC, this breaker is specifically engineered to safely clear severe short circuits in commercial tenant main and group metering applications.
Can I adjust the trip settings on the CVH3225?
No. This breaker features a fixed thermal magnetic trip unit. The long-time and instantaneous protection parameters are factory-set and cannot be modified in the field.
Are Eaton and Cutler-Hammer CVH3225 breakers identical?
Yes. Eaton manufactures this product line, and current Eaton CVH3225 breakers are fully interchangeable with older units that were branded as Cutler-Hammer.
Does the CVH3225 provide ground fault or arc fault protection?
No. This is a standard thermal magnetic circuit breaker designed for overload and short circuit protection. It does not feature integrated ground fault or arc fault circuitry.
