Eaton Specification Sheet - CVS3100W
Feature: 42 kAIC interrupt rating provides high fault clearance to protect feeders during short circuits. This capability translates into reduced equipment damage and minimized downtime in critical power distribution, especially in CV frame, three-pole configurations used in commercial and light industrial panels. Feature: 100 A amperage rating aligns with common feeder protection for distribution blocks and main breaker compartments. This ensures precise protection without oversizing, lowering equipment costs and minimizing nuisance tripping while meeting NEC/UL expectations for panel installations. Feature: Three-pole CV frame design supports balanced, three‑phase protection for motors and MCCs, enabling clean coordination with downstream devices and simplified wiring schemes. Application: Ideal for load centers, panelboards, and motor control centers in industrial facilities. Feature: Wire size compatibility #6-4/0 AWG Cu/Al provides versatile, code-compliant termination options and minimizes inventory needs. Application: Suitable for mixed conductor types in modern distribution boards. Feature: UL 489 and CSA C22.2 No. 5 certifications ensure regulatory compliance and cross-border acceptance. Application: Critical for documentation-ready builds and customer audits. Feature: Limited lifetime warranty provides long-term protection on functional performance, reducing total cost of ownership. Application: Great for projects prioritizing lifecycle value and predictable maintenance budgeting.

FAQs
CVS3100W is designed to fit the CV frame and supports three-pole operation, enabling straightforward integration into Eaton CV load centers and similar panel assemblies. With a 100 A rating and 42 kAIC interrupt capacity, it coordinates with downstream devices to deliver reliable protection for three-phase circuits. The device ships without terminals, so users can select compatible wiring terminals per project specs and code requirements.
Key specifications include a 100 A amperage rating, 42 kAIC interrupt rating, three-pole configuration, CV frame type, and wire size compatibility of #6-4/0 AWG Cu/Al. The breaker is UL 489 and CSA C22.2 No. 5 certified, with a weight of 4.4 lb and dimensions around 7.5 in length by 5 in height and width. Terminals are not included.
Yes. The CVS3100W fits CV-frame MCCB applications and three-pole circuits common in motor control centers and load centers. Its 100 A rating and 42 kAIC interrupt capacity provide protection for frequent fault scenarios in industrial settings, while UL 489 and CSA certification ensure regulatory compliance. Its compact footprint and absence of terminals simplify field installation in standardized panels.
The CVS3100W carries UL 489 and CSA Std. C22.2 No. 5 certifications, ensuring compliance with North American electrical protection standards. These approvals support project documentation, safety audits, and cross-border installations. When specifying, reference the CV frame, three-pole configuration, and 100 A rating to confirm alignment with local electrical codes and panel assembly requirements.
Total cost of ownership is driven by the device price, long-term reliability, and reduced maintenance visits due to reliable fault clearance. The CVS3100W offers a limited lifetime warranty and a robust 42 kAIC interrupt rating, which minimizes nuisance trips and spare parts. Its compatibility with standard wiring and CV frames helps reduce installation time and training costs for maintenance teams.
