FAQs
The CVS3150W is a three-pole unit designed for CV frame panels and load centers. It ships without terminals, so install with appropriate lugs or connectors for Cu/Al #6-4/0 conductors. Ensure enclosure clearance and mounting in standard electrical panels to maintain proper heat dissipation and accessibility for maintenance.
With a 150 A rating and a 42 kAIC interrupt capacity, CVS3150W provides robust protection for motor loads and distribution circuits. Its three-pole design supports balanced three-phase systems, enabling reliable tripping in short-circuit and overload events while maintaining system continuity in controlled conditions.
Yes. The CVS3150W carries CSA Std. C22.2 No. 5 and UL 489 certifications, ensuring compliance for panel boards and control enclosures. This reduces regulatory risk during audits and simplifies procurement for regulated facilities.
Best suited for load centers and motor-control panels in industrial environments, CVS3150W fits standard enclosures and supports three-phase distribution. Its compact size, rating, and CV frame make it ideal for panel boards in machine rooms, processing lines, and utility service disconnects.
The breaker’s limited lifetime warranty and high interrupt capacity reduce downtime and spare-part needs by delivering predictable performance under fault conditions. Its compatibility with Cu/Al wiring and standard CV frame panels streamlines upgrades and routine servicing, contributing to lower lifecycle costs and faster project delivery.
