Eaton Specification Sheet - CVS3100X
The CVS3100X uses a molded case design within the CV frame to deliver reliable overcurrent protection for industrial panels. The 100 A rating paired with a 42 kAIC interrupt capacity translates into fast fault clearing, reducing damage to downstream equipment and limiting downtime. This makes it ideal for distribution boards, machine control panels, and OEM equipment where dependable protection is essential. Three-pole construction with Cu/Al terminals and a maximum load of #4/0 kcmil supports versatile wiring schemes. It simplifies field connections, minimizes installation time, and maintains rigorous conductor sizing, making it well-suited for multi-line feeders in manufacturing lines and process systems where both copper and aluminum conductors are present. Certifications and standards meet UL 489 and CSA requirements, providing regulatory compliance across North America. This delivers confidence during audits and supports safety-certified control cabinets for industrial plants. Its compact dimensions and modest weight—7.5 in long, 5 in high and wide, about 3 lb—facilitate installation in tight enclosures, reducing panel redesigns and procurement complexity for faster project turnover. The limited lifetime warranty and Eaton ecosystem compatibility ensure long-term reliability and serviceability, minimizing spare parts headaches and simplifying upgrades across load centers and distribution panels.
