Product FAQs
8 answersWhich Eaton metering enclosures are compatible with this 100A main breaker?
It is designed for use as a tenant or main breaker within Eaton 1MM, 3MM, and 1MP modular meter stacks that require a 3-pole, bolt-on footprint.
What size wire can be installed in the lugs of the CVH3100X?
The factory-installed mechanical lugs accept copper or aluminum conductors ranging from 6 AWG up to 4/0 AWG.
Does this 3-pole breaker offer field-adjustable trip settings?
No, it features a fixed thermal and fixed magnetic (LI) trip unit. The long-time and instantaneous trip functions are factory-calibrated and non-adjustable.
How does this breaker mount into the meter stack?
It utilizes a bolt-on connection, fastening directly to the busbars inside compatible Eaton modular metering enclosures to provide a secure, low-resistance termination.
Can the CVH3100X safely interrupt high fault currents in commercial applications?
Yes, the CVH frame provides a high interrupting rating of 100kAIC at 240VAC, allowing it to be installed safely in electrical systems with substantial available fault current.
What is the difference between Eaton CVS, CV, and CVH series breakers?
These frames share the same physical footprint but differ by their short-circuit interrupting ratings. The CVH3100X provides 100kAIC at 240VAC, whereas the CV series is rated for 65kAIC and the CVS series for 42kAIC.
Is the CVH3100X suitable for both copper and aluminum wiring?
Yes, the standard mechanical lugs are dual-rated for both Cu and Al conductors. Electricians should ensure properly rated antioxidant compound is applied when terminating aluminum wire.
Can I use this Eaton breaker in a single-phase residential panel?
No, the CVH3100X is a 3-pole breaker designed exclusively for three-phase systems. It will not fit in standard single-phase residential load centers.
