Eaton CVS3080 Molded Case Circuit Breaker - 42 kAIC
Part Number: CVS3080
Quick Summary
CVS3080 is a molded case circuit breaker designed for main power protection in industrial electrical panels. Engineers often contend with nuisance trips, difficult wiring, and crowded enclosures, and CVS3080 helps by delivering robust overload protection in a compact footprint. Certified to CSA Std. C22.2 No. 5 and UL 489, this device supports compliant installation across industrial and commercial environments. With an 80 A rating, 42 kAIC interrupt capacity, and a CV frame, it enables reliable main protection while reducing panel size and installation complexity. In practice, this translates to lower lifecycle costs, easier sourcing, and faster commissioning for power distribution systems.

Eaton Specification Sheet - CVS3080
Feature → Business Impact → Application: The CVS3080 delivers an 80 A rating with a 42 kAIC interrupt capacity, providing robust overcurrent protection for three-phase feeders and reducing the likelihood of costly equipment damage in manufacturing lines and process systems. This translates to minimized downtime and improved safety margins in critical power circuits. Feature → Application: The CV frame and three-pole design ensure balanced protection across all phases, enabling predictable trip behavior and simpler coordination with downstream devices in industrial panels and load centers. Feature → Application: Terminals sized for #6-4/0 kcmil line and load and wiring up to #6-4/0 AWG Cu/Al simplify field terminations and stock management, accelerating installation and reducing conduit and wiring complexity. Feature → Application: The compact 7.5 in depth, 5 in height, and 5 in width footprint with a 4.4 lb weight supports plastic and metal panel integration and easier retrofits. Feature → Application: UL 489 and CSA certification provide regulatory confidence, while a limited lifetime warranty reduces life-cycle risk and total cost of ownership for electrical protection across facilities. This combination supports reliable main protection, compliance assurance, and cost-effective maintenance in industrial environments, including load centers, control panels, and distribution systems.

FAQs
CVS3080 is designed for three-pole, CV-frame installation in industrial panels. When mounting, ensure alignment with standard DIN-rail or panel mounting provisions used by Eaton MCCBs, verify clearance for terminal access, and use torques specified by the manufacturer for #6-4/0 kcmil line and load connections. The device supports copper or aluminum conductors in the range indicated, simplifying wiring schemes for new builds or retrofits.
Key specs include an 80 A amperage rating, a 42 kAIC interrupt capacity, three-pole operation, CV frame type, and terminals rated for #6-4/0 kcmil line and load. Wire size accepts #6-4/0 AWG Cu/Al. The unit weighs 4.4 lb and has dimensions of approximately 7.5 in (L) × 5 in (W) × 5 in (H). Certifications include UL 489 and CSA Std. C22.2 No. 5, with a limited lifetime warranty.
Yes. CVS3080 is specifically designed as a main breaker for three-phase systems in industrial panels and load centers. Its 80 A rating and 42 kAIC interrupt capacity support reliable fault interruption, while the CV frame and three-pole configuration provide coordinated protection across phases. Its compact dimensions help with panel density, and the line/load terminal sizing ensures robust termination for feeders.
CVS3080 carries UL 489 and CSA Std. C22.2 No. 5 certifications, confirming compliance with essential safety and performance standards for circuit breakers used in industrial electrical systems. These certifications reduce regulatory risk during procurement, support safe operation in demanding environments, and facilitate acceptance in North American industrial and commercial applications.
The CVS3080 offers a limited lifetime warranty and a compact footprint that can reduce panel size and installation time, lowering upfront and ongoing costs. High interrupt rating (42 kAIC) reduces the risk of downstream damage, potentially lowering downtime and maintenance costs. Its compatibility with Cu/Al conductors and standard terminal sizing also simplifies sourcing and spare-part inventory, contributing to a lower total cost of ownership over the equipment lifecycle.
