Product FAQs
5 answersWhich Eaton meter stacks accept this main breaker?
The CVS3175X is specifically designed to bolt into Eaton 35MM and 37MM meter stacks, as well as compatible group metering enclosures used in multi-tenant facilities.
Is the CVS3175X a suitable replacement for older CHH breakers?
Yes, this CV frame breaker is designed as a direct replacement for legacy Cutler-Hammer CHH main breakers, allowing you to upgrade existing meter stacks without modifying the enclosure.
How are conductors terminated on the CVS3175X?
This bolt-on breaker features standard load lugs that accept either copper or aluminum wire from 6 AWG up to 4/0 kcmil, making it suitable for standard 175-amp service entrance conductors.
How does the trip mechanism operate during a fault?
The breaker uses a fixed thermal magnetic trip unit. The thermal component provides long time protection against sustained overloads, while the magnetic component delivers instantaneous tripping during severe short circuits.
What does the 42kAIC rating indicate for this tenant main?
The 42kAIC interrupting rating means the breaker can safely clear fault currents up to 42,000 amps at 240V without sustaining internal damage, which is often required in commercial group metering applications.
