FAQs
The CVS3070W is a three-pole molded case circuit breaker designed for CV frame panels with a 70 A rating and 42 kAIC interrupt capacity. It is manufactured without terminals, accepting #6-4/0 AWG Cu/Al conductors. Ensure the panel bus and mounting provisions match CV series devices and follow UL 489 installation guidelines for safe operation.
Key specs include 70 A maximum current rating, 42 kAIC interrupt rating, three-pole configuration, and a CV frame type. It is a molded case circuit breaker intended for three-phase feeders, with wire sizes #6-4/0 AWG Cu/Al and terminals not included, enabling straightforward integration into compatible panels.
Yes. With a 70 A rating and 42 kAIC interrupt capacity, CVS3070W offers strong short-circuit protection for three-phase motor feeders and distribution panels. Its CV frame compatibility and compact form factor support efficient integration in motor control centers and load centers, helping protect motors and drive systems from faults.
CVS3070W carries UL 489 and CSA Std. C22.2 No. 5 certifications, ensuring compliance with North American safety and performance standards. These certifications simplify regulatory approvals, inspections, and maintenance planning for industrial installations across jurisdictions that require recognized electrical protections.
The unit includes a limited lifetime warranty, signaling long-term reliability and support. In practice, this reduces replacement risk and total cost of ownership for facilities with ongoing protection needs in harsh or high-demand environments, while providing predictable service intervals for preventive maintenance.
