Product FAQs
5 answersWhat meter stacks are compatible with the CVS2125XMM breaker?
This breaker is designed for use as a tenant main circuit breaker in Eaton 1MP, 1MM, and 3MM residential group metering stacks.
What do the X and MM in the CVS2125XMM catalog number indicate?
The X indicates that the breaker is equipped with load terminals that accept up to 4/0 kcmil wire. The MM indicates that it includes the mounting kit required for installation in Eaton 1MP, 1MM, and 3MM residential meter stacks.
What is the difference between Eaton CVS, CV, and CVH circuit breakers?
These breakers share the same physical frame but have different interrupting capacities at 120/240V. The CVS series is rated at 42 kAIC, the CV series at 65 kAIC, and the CVH series at 100 kAIC.
Can I use a CV series breaker in place of a CCV series breaker?
No. While they may appear similar, Eaton CV breakers are designed primarily for residential group metering applications, whereas CCV breakers are intended for commercial settings. Always verify the required breaker type for your specific panelboard or meter stack.
How is the CVS2125XMM installed in a meter stack?
This is a bolt-on tenant main breaker. It secures directly to the bus of compatible Eaton 1MP, 1MM, and 3MM modular metering stacks using the included mounting hardware kit.
