Eaton Specification Sheet - CVS2175Y3
Feature → Business Impact → Application: High interrupt rating of 42 kAIC reduces fault-energy exposure and minimizes collateral damage to downstream equipment, enabling safer start-ups and extended motor life in heavy-duty industrial feeds. This translates to fewer unplanned outages and lower maintenance costs for manufacturing lines and distribution panels. Feature → Application compatibility with a CV frame and two-pole design simplifies retrofits and new installations within existing Eaton systems, ensuring quick integration into current load centers and panel boards. Use this in commercial and light industrial facilities requiring dependable protection without custom wiring. Feature → Terminal flexibility with #6-4/0 AWG Cu/Al and #300 kcmil maximum line options (with terminal shield when using #300 kcmil) provides scalable conductor termination for large feeders, reducing termination time and improving bus integrity. Suitable for tenant main breaker roles in complex electrical rooms. Feature → Robust certifications (UL 489, CSA Std. C22.2 No. 5) reinforce regulatory compliance and safe operation, supporting pass-through inspections and enterprise-wide safety programs. Implement this in regulated environments where formal certification is a gatekeeper for commissioning. Feature → Compact dimensions (11.38 in L, 6.2 in H, 6.3 in W) and limited component count streamline installation in constrained spaces, helping electrical contractors and OEMs maximize panel density and simplify spare-part stocking. Apply in space-constrained load centers and retrofit projects where footprint matters. Feature → Limited lifetime warranty provides long-term protection against product failures, improving total cost of ownership and predictable maintenance budgets for facility managers and integrators. Use this for long-span projects where service continuity and vendor support are critical.

FAQs
CVS2175Y3 is a CV frame, two-pole molded case circuit breaker designed for Eaton CV assemblies. It mounts in standard CV-panel configurations, supporting #6-4/0 AWG Cu/Al conductors. For large feeder applications using #300 kcmil, a terminal shield is required and adds about 1.5 inches to the length, ensuring safe, code-compliant terminations in crowded panels.
The CVS2175Y3 provides a 175 A continuous rating with a 42 kAIC interrupt capability. It is suitable for two-pole protection and supports Cu/Al conductors from #6 up to #4/0 AWG. Its CV frame is designed to handle moderate to heavy load centers, with compatibility for panel boards and load centers used in industrial settings.
Yes, with its high interrupt rating (42 kAIC) and 175 A nominal rating, CVS2175Y3 offers reliable protection for critical feeders and motor circuits in manufacturing plants. Its UL 489 and CSA C22.2 No. 5 certifications reinforce compliance, while the two-pole design supports essential protection schemes in spare/tenant main breaker roles.
CVS2175Y3 is certified under UL 489 and CSA Std. C22.2 No. 5, ensuring compliance with common North American electrical safety and performance standards. These certifications support safe installation, reliable operation, and smoother inspection workflows for industrial facilities and electrical contractors.
Eaton provides a limited lifetime warranty for the CVS2175Y3, reflecting confidence in long-term reliability and reduced replacement costs. In practice, this supports lower total cost of ownership and predictable maintenance budgeting for facility managers and system integrators working with Eaton power distribution products.
