Eaton CVS2125Y Molded Case Circuit Breaker - 42 kAIC

125 A two pole molded case breaker uses the CV frame to deliver precise overload protection in industrial panels. The robust trip curve and rugged contacts reduce nuisance trips during routine startup and load fluctuations. As a main or tenant breaker, it supports compact load centers while maintaining clear fault isolation for downstream equipment. With a 42 kAIC interrupt rating, it clamps fault energy quickly, reducing conductor damage and downstream disruptions. In high fault risk environments like motor feeders or drives, that reliability translates to measurable uptime and safer maintenance windows. Terminals accept up to #4/0 kcmil maximum line and wire sizes from #6 through #4/0 AWG Cu/Al, offering wiring flexibility for diverse plants. This reduces the need for multiple breaker types and simplifies stocking, while enabling safe service in both new builds and retrofits. Compact dimensions and light weight help install in tight panels. The 7.5 in depth, 5 in height, and 3.5 in width fit standard enclosures, while the 2.75 lb mass speeds field replacement and reduces handling fatigue during panel upgrades. Durable construction, UL 489 and CSA certification, and a limited lifetime warranty deliver long term value. The device supports electrical code compliance and minimizes maintenance risk over the life of the distribution system. Compatibility with Eaton CV series panels ensures straightforward replacement with consistent trip characteristics. Field teams benefit from standardized terms and faster commissioning, improving ROI on new builds and retrofit projects.
