Eaton CVS2125XMM Molded Case Circuit Breaker - UL 489/CSA
Part Number: CVS2125XMM
Quick Summary
Eaton CVS2125XMM Molded Case Circuit Breaker provides robust overcurrent protection for CV frame panels. Engineers confront compatibility gaps, mounting complexity, and downtime when upgrading tenant protection in existing assemblies. This device delivers UL 489 and CSA Std. C22.2 No. 5 certifications along with a limited lifetime warranty, underscoring reliability for mission-critical applications. With a 125 A rating and a 42 kAIC interrupt capacity, the two‑pole CVS2125XMM fits CV-frame panels while maintaining compact form. It supports #6-4/0 AWG Cu/Al conductors and #4/0 kcmil maximum load, and includes a mounting kit for fast, tool-agnostic installation. This combination reduces panel downtime, simplifies compliance checks, and lowers total cost of ownership in commercial and light industrial settings.
