Product FAQs
5 answersWhat meter stacks are compatible with the CVS3100X breaker?
This breaker is designed for use in Eaton 35MM and 37MM commercial meter stacks and group metering applications. It is not intended for 1MP, 1MM, or 3MM residential stacks, which require breakers with an MM suffix for the proper mounting hardware.
What does the X suffix indicate in the CVS3100X catalog number?
The X suffix designates that the breaker is factory-equipped with load-side lugs that accept up to 4/0 kcmil wire. The line side features a bolt-on connection designed to mount directly to the meter stack bus.
What is the difference between the CVS3100X, CV3100X, and CVH3100X?
The prefix indicates the short-circuit interrupting rating of the breaker frame. The CVS3100X is rated for 42 kAIC, the CV3100X is rated for 65 kAIC, and the CVH3100X provides 100 kAIC at 240V AC. All three share the same physical dimensions and mounting style.
Can the trip settings be adjusted on the CVS3100X?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The Long-Time (L) and Instantaneous (I) protection settings are factory calibrated and cannot be modified in the field.
Can this 3-pole breaker be used for single-phase tenant feeds?
No, the CVS3100X is a 3-pole breaker designed specifically for 3-phase tenant feeds. For single-phase applications, a 2-pole breaker from the CV family, such as the CVS2100X, is required.
