FAQs
CVS2080Y is designed for CV frame panel installations and requires confirming enclosure compatibility with the CV frame family. Ensure the busbar space, torque spec for #4/0 kcmil terminals, and conductor sizing meet #6-4/0 AWG Cu/Al ratings. Follow UL 489 mounting guidelines and secure the unit with proper hardware to maintain reliable operation and safe terminations.
With an 80 A rating and 42 kAIC interrupt capacity, CVS2080Y protects feeders and branch circuits in load centers and control panels. The two-pole design simplifies wiring, while the CV frame ensures mechanical compatibility with Eaton and third-party bus systems. Its compact footprint facilitates dense panel layouts and reduces material costs.
Key specs include an 80 A amperage rating, a 42 kAIC interrupt rating, a two-pole configuration, a CV frame type, and terminal capacity up to #4/0 kcmil line. Also consider wire size compatibility (#6-4/0 AWG Cu/Al) and certifications UL 489 and CSA. These values determine protection accuracy, fault tolerance, and regulatory compliance.
CVS2080Y carries UL 489 and CSA Std. C22.2 No. 5 certifications, indicating compliance with essential safety and performance standards for low-voltage circuit breakers. These certifications simplify qualification for panel builds, guarantee consistent protection performance, and support warranty coverage in regulated industrial environments.
The device’s limited lifetime warranty, robust build, and standard CV frame availability reduce lifecycle risk and spare parts complexity. With fewer nuisance trips and straightforward replacement in existing panels, maintenance downtime is minimized and stocking is streamlined, delivering a favorable total cost of ownership for manufacturing facilities and service teams.
