Eaton Specification Sheet - CVS3175W
Feature: The CVS3175W employs a 175 A rating on the CV molded case frame, delivering robust protection for mid-size, three-pole, three-phase feeders. Business Impact: This rating aligns with typical plant loads, improving fault current coordination and reducing nuisance trips, which translates to less unplanned downtime. Application: Ideal for Eaton load centers, switchgear, motor control centers, and panelboards in manufacturing facilities and data centers, where reliable protection is essential. Feature: 42 kAIC interrupt rating ensures fast clearing of high-energy faults. Business Impact: This minimizes damage to transformers, buses, downstream equipment, and costly secondary failures, resulting in lower repair costs and shorter downtime. Application: Suitable for facilities with elevated fault currents, including industrial automation rows, packaging lines, and critical data-center support rooms where continuity is paramount. Feature: Terminals without included lugs enable field-terminated wiring with customer-supplied hardware. Business Impact: Provides flexible terminations that match existing panel hardware and wire practices, reducing procurement and installation time. Application: Ideal for retrofit projects, custom panel builds, and installations where termination type varies. Feature: UL 489 and CSA Std. C22.2 No. 5 certifications provide regulatory compliance and procurement parity. Business Impact: Streamlines supplier qualification, reduces regulatory risk, and simplifies cross-border sourcing. Application: Use in NA-based projects requiring certification to UL/CSA standards, such as facility infrastructure and automation systems. Feature: Compact dimensions and light weight improve installation efficiency. Business Impact: A 7.5 in depth, 5x5 in footprint and 4.4 lb weight free panel space, shorten assembly time and reduce shipping costs. Application: Particularly beneficial in space-constrained control panels, MCCs, and load centers in industrial environments.

FAQs
Install CVS3175W by aligning the three-pole assembly with the panel’s bus structure, ensuring proper vertical clearance and secure mounting within the load center or MCC enclosure. Since terminals are not included, select appropriate lugs or termination hardware compatible with #6-4/0 AWG Cu/Al conductors. Follow UL 489 wiring guidelines and confirm bus bar alignment to maintain proper arc flash separation.
CVS3175W carries UL 489 and CSA Std. C22.2 No. 5 certifications, signaling compliance with North American electrical standards. These certifications simplify supplier qualification, ensure safe operation under typical industrial conditions, and support cross-border procurement for multinational facilities. They also help satisfy internal safety policies and customer compliance requirements during audits.
Yes. The 42 kAIC interrupt rating provides fast, reliable fault clearance for high-energy events, protecting downstream equipment and reducing trip-induced downtime. For motor starting transients, coordinate with downstream protection devices to prevent nuisance trips, and assess motor inrush with your MCC design to maintain stable operation.
Absolutely. The CVS3175W uses the CV frame and a three-pole configuration, designed for seamless integration with Eaton load centers and motor control centers. Its compact footprint and field-termination flexibility (without terminals) support retrofit projects and streamlined stocking within existing Eaton protection schemes.
The CVS3175W delivers reduced downtime due to fewer nuisance trips, improved fault current coordination, and regulatory compliance with UL/CSA standards. While initial costs may be higher than smaller breakers, the combination of higher interrupt rating, durability, and compatibility with Eaton systems typically yields lower maintenance costs, faster serviceability, and longer equipment life, improving total cost of ownership.
