FAQs
Yes. CVS3090X is a three-pole molded case circuit breaker designed for the CV frame and tenant main breaker use in CV-series load centers. It supports up to #4/0 kcmil maximum load and conducts up to #6-4/0 AWG Cu/Al, facilitating straightforward pairing with standard Eaton CV components for modular panel protection.
The device is rated at 90 A with a 42 kAIC interrupt rating, three poles, and uses a CV frame. Terminals accommodate #4/0 kcmil maximum load, with wire sizes #6-4/0 AWG Cu/Al. Its compact 7.5 in length, 5 in height, and 5 in width suit tight panel environments while delivering reliable short-circuit protection.
Yes. CVS3090X carries UL 489 certification and CSA Std. C22.2 No. 5 certification, confirming compliance with safety standards for molded case circuit breakers and ensuring safe integration into industrial control panels and electrical cabinets.
CVS3090X supports termination with Cu/Al conductors ranging from #6 to #4/0 AWG and up to #4/0 kcmil maximum on the load side. This makes it compatible with common enclosure wiring schemes and simplifies field wiring, reducing termination errors during panel fabrication and rework.
The CVS3090X carries a limited lifetime warranty, providing long-term protection and lower total cost of ownership. For maintenance, follow standard inspection practices: verify tight terminations, check for signs of overheating or corrosion, and ensure continued UL 489/CSA compliance through periodic reviews during panel servicing.
