Eaton Specification Sheet - CVS3090Y
Feature → Business Impact → Application: 90 A amperage rating with three-pole CV frame delivers targeted protection for medium-load panels, reducing nuisance trips while supporting reliable power distribution in industrial equipment. This translates to fewer unplanned shutdowns and improved line uptime in manufacturing lines and control panels. Application: CV panelboards and MCCs requiring robust main-breaker protection without excessive footprint. Feature → Business Impact → Application: 42 kAIC interrupt rating provides strong fault current withstand, protecting downstream equipment and wiring from damage during short circuits. Application: high-current feeders and dense electrical rooms where fault levels are elevated. Feature → Business Impact → Application: Terminals supporting #6-4/0 AWG Cu/Al and maximum line of #4/0 kcmil enable flexible, fast wiring with common conductors, reducing installation time and labor costs. Application: new installs and retrofits in data centers, process lines, and packaging machinery. Feature → Business Impact → Application: Compact dimensions (7.5 in L, 5 in W, 5 in H) and 4.4 lb weight simplify enclosure packing, improve panel density, and ease retrofit projects. Application: space-constrained control panels and load centers. Feature → Business Impact → Application: CSA Std. C22.2 No. 5 and UL 489 certifications provide regulator-aligned safety compliance, lowering audit risk and enabling easier procurement for regulated industries. Application: manufacturing facilities and systems requiring certified protection. Feature → Business Impact → Application: Limited lifetime warranty reduces long-term ownership costs and supports predictable maintenance budgeting. Application: capital projects and ongoing plant reliability programs.

FAQs
CVS3090Y is designed for CV frame panelboards and MCCs with three-pole construction. It accepts #6-4/0 AWG Cu/Al conductors and supports up to #4/0 kcmil on the line side, enabling straightforward integration into standard CV-based assemblies and minimizing rewiring during upgrades.
A 42 kAIC interrupt rating indicates the breaker can safely interrupt fault currents up to 42 kiloamps. This reduces the risk of equipment damage and improves safety in high-short-circuit scenarios typical of medium-to-large industrial feeders and panelboards.
Yes. CVS3090Y carries UL 489 and CSA Std. C22.2 No. 5 certifications, confirming compliance with widely adopted safety and performance standards for low-voltage molded case breakers used in industrial applications.
The 90 A rating, compact 7.5 in by 5 in by 5 in footprint, and 4.4 lb weight simplify installation in crowded panels. The long-term warranty and certified construction also support reduced maintenance risk and predictable lifecycle costs in factory automation environments.
By combining a robust 42 kAIC interrupt capability with certified safety (UL 489, CSA), a proven CV frame, and compatible termination options, CVS3090Y minimizes downtime during upgrades, speeds commissioning, and delivers dependable protection that lowers total cost of ownership over the device’s lifetime.
