Eaton Specification Sheet - CVS2125W
The 42 kAIC interrupt rating delivers robust fault protection, reducing arc flash exposure and equipment damage. This two-pole CV frame unit provides reliable tripping behavior across standard industrial feeders, enabling predictable protection in the event of a short circuit. In practice, it supports quick replacement in existing Eaton CV panel arrays, minimizing downtime during maintenance or upgrades. The 125 A amperage rating with two poles provides reliable main protection for feeders and sub-feed circuits while preserving space in crowded panels. Wide wire compatibility is offered with #6-4/0 AWG Cu/Al conductors, simplifying integration with diverse supply runs without reengineering buswork. The terminals are not included, offering installation flexibility to pair with customer-supplied lugs or bus bars for streamlined retrofit projects. Certifications from UL 489 and CSA ensure ongoing compliance and audit readiness, reinforcing safety commitments with a limited lifetime warranty that supports total cost of ownership reduction. The compact dimensions (7.5 in L x 5 in H x 3.5 in W) and modest weight (2.75 lb) ease handling and field placement in confined spaces.

FAQs
CVS2125W is a two-pole molded case circuit breaker designed for Eaton CV frame panels. It fits standard industrial distribution setups, supports #6-4/0 AWG Cu/Al conductors, and integrates with load centers and switchgear that use the CV family. Note terminals are not included, so compatibility with user-supplied lugs or bus bars is required for field wiring.
The CVS2125W offers a 125 A amp rating and a 42 kAIC interrupt rating, enabling robust fault protection for main feeders. It is a two-pole device with a CV frame, without terminals, and is certified to UL 489 and CSA standards, aligning with common industrial protection requirements and safety audits.
Yes. With a 125 A main protection rating and 42 kAIC interrupt capacity, the CVS2125W is well-suited for industrial control panels and load centers that require reliable main-breaker protection. Its compact CV frame and two-pole design support easy integration into existing Eaton CV configurations, reducing retrofit complexity.
CVS2125W carries UL 489 and CSA standards (CSA Std. C22.2 No. 5), ensuring compliance with recognized safety and performance benchmarks for low-voltage circuit breakers. These certifications simplify regulatory approvals, supplier qualification, and routine audits, delivering peace of mind for critical infrastructure projects.
The CVS2125W comes with a limited lifetime warranty, reflecting Eaton’s commitment to long-term reliability. Since it is a molded case breaker with no terminal hardware included, routine maintenance is minimal; expect stable performance under normal electrical loading and periodic verification during preventive maintenance cycles.
