Eaton Specification Sheet - CVS3100
Feature to benefit mapping is used throughout to connect specifications with real-world outcomes. The CVS3100 delivers a 100 A amperage rating with a 42 kAIC interrupt capacity, which translates to robust fault clearance and reduced downstream damage in demanding industrial environments. This improves equipment uptime and protects critical loads, especially in motors and drives applications where short-circuit events are a risk. The CV frame and three-pole design provide balanced protection for three-phase systems, enabling easier panel integration and safer fault isolation in control panels and load centers. Terminations accept #6-4/0 kcmil Cu/Al conductors, supporting flexible wiring options and straightforward field assembly in both copper and aluminum installations. With a compact footprint (7.5 in L, 5 in W, 5 in H) and a weight of 4.4 lb, it fits tight enclosures and reduces service time during upgrades. The limited lifetime warranty and UL 489 CSA certifications give operators confidence in long-term compliance, maintenance planning, and total cost of ownership. Compatibility with Eaton CV-series components ensures streamlined part sourcing, standardized mounting, and predictable performance across multiple projects, from OEM builds to retrofit installations.
