Eaton Specification Sheet - CVS2225Y
Feature: 225 A rating with a 42 kAIC interrupt rating on a two-pole CV molded case breaker. Business Impact: This combination delivers robust short-circuit protection, minimizes nuisance trips, helps prevent equipment damage, and reduces unplanned downtime across critical production lines. Application: Use as the main protective device in CV frame panels, motor control centers, and distribution boards across manufacturing and data-center environments, with straightforward field replacement and predictable trip curves. Feature: Wire and terminal compatibility — supports #6-4/0 AWG Cu/Al and #4/0 kcmil maximum line, enabling flexible feeder configurations. Business Impact: Simplifies field wiring, reduces labor time, ensures secure, code-compliant terminations that preserve conductor integrity and enable faster commissioning. Application: Ideal for heavy feeders and service entrances in industrial panels and load centers requiring large conductor runs, frequently deployed in OEM builds and retrofits. Feature: Compact footprint and weight — 7.5 in depth, 5 in height, 3.5 in width; 2.75 lb, enabling easier handling and space optimization in crowded switchgear. Business Impact: Enables installation in tight panels, reduces panel density, lowers shipping costs, and simplifies on-site logistics during upgrades. Application: Suitable for retrofit projects and new builds in spaces where clearance, enclosure footprint, and mounting orientation are critical considerations. Feature: Certifications and warranty — UL 489, CSA Std. C22.2 No. 5 listings; Limited lifetime warranty supports long-term reliability. Business Impact: Ensures regulatory compliance, predictable performance, and lower lifecycle risk through proven protection and long-term support, reducing spare-part inventories. Application: Appropriate for OEM builds and service contracts in manufacturing, data centers, and critical infrastructure demanding durable protection and straightforward commissioning. Feature: Catalog integration and compatibility — Catalog Number CVS2225Y with CV frame interoperability and documented mounting dimensions for plan reviews. Business Impact: Streamlines procurement, improves interchangeability across Eaton components, reduces downtime during upgrades, and accelerates project delivery.

FAQs
CVS2225Y is designed for CV frame panels and distribution gear. Verify frame type, mounting pattern, and bus connection alignment with the Eaton CV frame family. Confirm the catalog number CVS2225Y, two-pole configuration, and the terminal limits of #4/0 kcmil maximum line. Ensure panel clearance and wiring space meet the 7.5 in x 5 in x 3.5 in envelope. When in doubt, consult Eaton wiring diagrams and panel specification sheets.
42 kAIC indicates the maximum fault current at which the CVS2225Y can safely interrupt without damage. This supports protection of downstream equipment and coordination with upstream devices. In high fault-current environments like industrial motor feeds, this rating helps prevent cascading failures and enables proper selectivity with upstream protective devices to minimize downtime.
Yes. CVS2225Y carries UL 489 and CSA Std. C22.2 No. 5 listings, validating its conformity to recognized safety and performance requirements for molded case circuit breakers. This compliance supports regulatory adoption in industrial facilities, OEM builds, and service contracts, helping ensure code-compliant protection across diverse electrical installations.
Consider the dimensional envelope (7.5 in x 5 in x 3.5 in) and the weight (2.75 lb) for handling and mounting. Use conductors within #6–4/0 AWG Cu/Al and respect the #4/0 kcmil maximum line terminal. Ensure proper torque on terminal lugs, secure mounting to CV frame devices, and provide adequate clearance for heat dissipation and service access during maintenance.
CVS2225Y is backed by a limited lifetime warranty, reducing long-term risk and replacement costs. Consider lifecycle costs including spindle wear, contact reliability, spare parts availability, and annual maintenance needs. Coupled with UL/CSA listings, the device supports predictable performance, lower downtime, and a favorable return on investment for industrial protections.
