Eaton Specification Sheet - CVS2090XMM
The CVS2090XMM provides a 90 A amperage rating with a 42 kAIC interrupt rating, delivering fast fault interruption that protects downstream equipment and wiring from overload and arc energy. In panel applications, this enables selective coordination with upstream devices and reduces downtime. The CV frame molded case design ensures compatibility with Eaton CV load centers and panel boards, simplifying stocking and installation while improving reliability across multi-site projects. Two-pole construction with a common trip reduces wiring complexity and guarantees synchronized shutdown during faults, saving time during commissioning and maintenance. Terminals accept up to #4/0 kcmil maximum load and work with wire sizes from #6-4/0 AWG Cu/Al, enabling direct termination of large feeders. A mounting kit is included to simplify field installation, and the breaker’s compact footprint (7.5 in L x 5 in H x 3.5 in W, 2.75 lb) makes it suitable for tight panel spaces. Compliance is reinforced by UL 489 and CSA Std. C22.2 No. 5 certifications, while the limited lifetime warranty adds long-term value and peace of mind for system integrators and end users.
