FAQs
CVS3070 is a three-pole molded case circuit breaker designed for CV frame panelboards and load centers. It accepts #6-4/0 kcmil Cu/Al conductors for both line and load, enabling straightforward integration into standard low-voltage distributions. Its 70A rating and 42 kAIC interrupt capacity suit main protection roles in many industrial applications.
The CVS3070 offers a 42 kAIC interrupt rating, meaning it can safely interrupt fault currents up to 42 kiloamps. This higher rating reduces the risk of equipment damage during short-circuit events and supports safer, faster fault isolation in high-energy industrial networks, contributing to improved equipment longevity and reduced downtime.
Yes. The CVS3070 is certified to UL 489 and CSA standards (CSA Std. C22.2 No. 5), ensuring compliance with common regulatory requirements for molded case circuit breakers. These certifications support smoother QA audits, code-compliant installations, and safer operation in industrial facilities.
CVS3070 supports Cu and Al conductors with line and load terminals rated for #6-4/0 kcmil, enabling flexible wiring configurations. This compatibility simplifies field assembly, reduces the need for adapters, and speeds up panel wiring while maintaining robust electrical performance.
The CVS3070’s limited lifetime warranty helps lower lifecycle costs by reducing replacement expenses. Its compact CV frame and straightforward wiring minimize installation time, while its high interrupt rating and code certifications reduce the likelihood of costly outages and compliance rework, delivering tangible savings in uptime, maintenance labor, and project commissioning.
