Eaton Specification Sheet - CVS2225Y3
High-current protection is guaranteed with a 225 A rating and a 42 kAIC interrupt rating, enabling rapid fault clearance to minimize equipment damage and downtime in power distribution and MCC environments. This translates to improved system reliability, reduced maintenance costs, and safer commissioning in demanding industrial settings. The CV frame, two-pole design simplifies panel layouts and replacements while delivering proven coordination with Eaton CV components for consistent protection across feeders and subfeeders. Terminals support #6-4/0 AWG Cu/Al conductors, with a maximum line size of #300 kcmil when a terminal shield is used, allowing large conductors to be run cleanly in compact enclosures and reducing splice points. The 7.5 in length, 5 in height, and 3.5 in width provide a compact footprint (weight 2.75 lb) suitable for crowded load centers and control panels. Catalog notes indicate that a terminal shield adds 1.50 inches to the length for #300 kcmil options, which should be factored into panel cutouts and mounting clearances. The product is UL 489 and CSA certified, backed by a limited lifetime warranty, which supports long-term maintenance planning and regulatory compliance in industrial facilities. Together, these specifications support efficient installation, predictable performance, and strong return on investment when protecting high-current circuits and critical loads within CV-series panelboards.

FAQs
CVS2225Y3 supports Cu/Al conductors from #6 up to 4/0 AWG, with a maximum line size of #300 kcmil when a terminal shield is used. The shield option adds 1.50 inches to the breaker length for large conductors, so plan enclosure space accordingly. It's a two-pole device designed for CV frame panel protection and straightforward field replacement.
Yes. CVS2225Y3 carries UL 489 and CSA Std. C22.2 No. 5 certifications, confirming compliance with US and Canadian electrical protection standards. This reduces procurement risk, supports regulatory approvals for panel boards and MCCs, and simplifies specification in cross-border projects where code compliance is critical.
CVS2225Y3 provides a 42 kAIC interrupt rating, which is suitable for many distribution and motor control applications requiring robust fault current protection. While some competing entries may offer lower ratings, this unit aligns with demanding industrial panels and CV-frame systems, delivering reliable interruption performance while maintaining compact dimensions and straightforward installation.
The breaker measures 7.5 inches in length, 5 inches in height, and 3.5 inches in width, with a weight of 2.75 pounds. It is designed as a two-pole molded case breaker within the CV frame. When using the #300 kcmil option, account for the additional shield-length extension of 1.50 inches. Mounting should align with standard CV panel cutouts and available space in load centers.
CVS2225Y3 is recommended for industrial electrical protection in load centers, panel boards, and motor control centers that require high-current, reliable protection. Its CV frame compatibility and large-conductor capability make it suitable for feeders and subfeeders in Eaton CV-series panels, offering straightforward replacement, compliant installation, and long-term operational value.
