Product FAQs
7 answersWhat equipment is the CVS3225X designed to be installed in?
This breaker is specifically designed for use as a tenant main circuit breaker in Eaton 35MM and 37MM meter stacks, as well as other compatible group metering applications.
Can the CVS3225X replace older Cutler-Hammer tenant main breakers?
Yes, this breaker serves as a direct replacement for older Cutler-Hammer CHH type tenant main breakers in compatible 35MM and 37MM commercial meter stacks.
What does the X suffix in the CVS3225X catalog number indicate?
The X suffix indicates that the breaker includes factory-installed load side lugs. In group metering applications, the line side bolts directly to the meter stack bus, while the load side lugs accept the outgoing tenant feeder wires.
Is the CVS3225X suitable for commercial metering facilities with high fault currents?
Yes. With an interrupting rating of 42kA at 240V AC, this breaker is engineered for commercial and multi-tenant residential group metering installations that require higher fault current protection than standard 10kA or 22kA rated breakers.
How does this breaker mount into the meter stack?
The CVS3225X utilizes a bolt-on mounting configuration. The line side bolts directly to the internal bus of the meter stack to establish a secure, high-capacity connection, while the load side uses the provided lugs for the tenant feeder cables.
What type of trip protection does the CVS3225X provide?
It features a thermal-magnetic trip unit with fixed long-time (thermal) and instantaneous (magnetic) functions. This ensures comprehensive protection for tenant feeder circuits against both sustained overloads and sudden short circuits.
Can I install the CVS3225X in a standard residential load center?
No. The CVS frame is purpose-built as a tenant main breaker for Eaton group metering enclosures and meter stacks. It is not physically compatible with standard residential load centers or standard panelboards.
