FAQs
The CVS3150Y is designed for CV frame panels and LV distribution setups. It supports three poles and accepts #6-4/0 AWG Cu/Al conductors with a maximum line terminal of #4/0 kcmil. Its compatibility with standard CV frame cabinets simplifies retrofits and new panel projects, reducing the need for separate protection devices.
Key specs include a 150 A rating and a 42 kAIC interrupt rating, three poles, and terminal capacity of #4/0 kcmil on the line with #6-4/0 AWG Cu/Al conductors. These ratings translate to reliable fault interruption for medium-load feeders, improved short-circuit energy handling, and compliance with typical LV distribution codes.
Yes. The CVS3150Y is purpose-built as a main tenant breaker with a CV frame and three-pole configuration, providing centralized protection for multi-branch circuits in industrial control panels. Its 150 A rating and UL 489/CSA certifications support safe, code-compliant operation in commercial and light industrial environments.
The CVS3150Y carries UL 489 and CSA Std. C22.2 No. 5 certifications, which validate safety and performance for molded case breakers in North American installations. These certifications simplify regulatory audits, ensure interchangeability with existing protection devices, and support ongoing maintenance and safety compliance across facilities.
The CVS3150Y delivers a reliable protection solution with a limited lifetime warranty and a compact footprint, reducing spare-part inventories and downtime during replacement.
