Product FAQs
5 answersWhat equipment is the CVH3125X designed to fit?
This 3-pole main breaker is designed for use in Eaton Commercial Meter Stacks, specifically 35MM and 37MM modules, where it serves as a tenant main circuit breaker.
What is the difference between the CVS3125X, CV3125X, and CVH3125X?
These catalog numbers represent different interrupting capacities for the same 125A, 3-pole CV frame breaker. The CVS3125X is rated at 42kAIC, the CV3125X is rated at 65kAIC, and the CVH3125X offers the highest rating at 100kAIC at 240V.
Can I adjust the trip settings on the CVH3125X?
No, this breaker uses a fixed thermal magnetic trip unit. Both the long-time and instantaneous (LI) protection settings are factory set and non-adjustable.
What type of wire is compatible with the CVH3125X lugs?
The terminals are rated for use with both copper (Cu) and aluminum (Al) conductors, accommodating wire sizes from 6 AWG up to 4/0 AWG.
What does the 100kAIC rating on the CVH3125X indicate?
It indicates the breaker can safely interrupt up to 100,000 amps of fault current at 240V AC. This high interrupting capacity is often required in commercial group metering applications where the available fault current exceeds standard residential levels.
