FAQs
CVS3070Y is a three-pole molded case circuit breaker designed for industrial control panels, load centers, and motor feeders. With a 70A rating and 42 kAIC interrupt capacity, it delivers reliable short-circuit protection for 3-phase systems while accommodating Cu/Al conductors up to #4/0 kcmil. Its UL 489 and CSA certifications support compliance in North American installations.
For a three-phase installation, CVS3070Y uses a three-pole configuration with terminals rated for #6-4/0 AWG Cu/Al conductors and a maximum line termination of #4/0 kcmil. Plan your panel layout to ensure proper phase balance, secure torque on terminations, and maintain required short-circuit current ratings. The CV frame supports straightforward field wiring with standard conduit and connector methods.
Yes. CVS3070Y carries UL 489 certification and CSA Std. C22.2 No. 5 verification, aligning with common industrial safety and electrical code requirements. These certifications help ensure compliance for electrical panels, minimize rework during audits, and support safer, more reliable protection for critical circuits.
When selecting CVS3070Y, verify that your panel supports the CV frame and three-pole configurations. Check the maximum terminal size (#4/0 kcmil) and ensure conductor routing accommodates the 7.5 in x 5 in x 5 in footprint. The CV frame is designed for compatibility with Eaton load centers and broader CV-series protection schemes, aiding plug-and-play integration.
CVS3070Y offers a limited lifetime warranty and high interrupt capacity, reducing replacement frequency and maintenance costs in high‑demand environments. Its compact form factor lowers enclosure costs, and UL/CSA certification supports faster commissioning by reducing validation time. Over the system lifetime, these factors translate into lower total cost of ownership and improved uptime.
