Product FAQs
6 answersCan the CVH3150 be installed in systems with lower fault current requirements?
Yes. With a maximum interrupting rating of 100kAIC at 240VAC, this breaker safely exceeds the requirements for systems needing 10kAIC, 22kAIC, 42kAIC, or 65kAIC protection.
Are the trip settings on the CVH3150 adjustable?
No. This breaker is equipped with a thermal-magnetic trip unit featuring fixed thermal (Long-Time) and fixed magnetic (Instantaneous) settings. They cannot be field-adjusted.
Do I need to purchase separate lugs for installation?
No. The breaker includes factory-installed line and load lugs designed to accept 6 AWG through 4/0 AWG copper or aluminum (Cu/Al) conductors.
What type of enclosure is required for a standalone installation of this breaker?
When not installed directly inside a panelboard or meter stack, the CVH3150 is designed to be mounted in Eaton Type ECC enclosures.
Can the CVH3150 be used as a tenant main breaker?
Yes. Eaton CV-frame breakers, including the CVH3150, are frequently used as tenant main breakers in multi-metering equipment and compatible panelboards.
What is the difference between the CV3150 and the CVH3150?
Both are 150A, 3-pole breakers in the Eaton CV frame family, but they have different interrupting ratings. The CV3150 is rated for 65kAIC, whereas the CVH3150 provides a higher 100kAIC rating.
