FAQs
Yes. CVS3175LL3 is a CV frame molded case circuit breaker designed for CV-frame panels. It accepts #6-4/0 AWG Cu/Al conductors and #300 kcmil line/load terminals, supporting standard LV distribution enclosures and main disconnects. This compatibility simplifies retrofits and new installations, ensuring straightforward mounting, alignment with existing bus systems, and reliable punch-down connections for secure field terminations.
CVS3175LL3 is rated for 175 A with a 42 kAIC interrupt capacity and is a three-pole device. This combination supports effective protection of three-phase loads in industrial power systems, enabling safe interruption during short-circuit events while handling substantial continuous current. The unit’s CV frame compatibility ensures consistent performance with other CV-series breakers.
This breaker is well suited for industrial automation panels, power distribution centers, and commercial/industrial load centers requiring robust main protection. Its high interrupt rating and three-pole configuration make it ideal for main disconnects in systems with large feeders and demanding duty cycles, helping minimize downtime and maintain continuous operation in manufacturing, processing, and assembly environments.
CVS3175LL3 carries UL 489 and CSA Std C22.2 No. 5 certifications, confirming compliance with safety and performance requirements for low-voltage circuit breakers. This matters for code compliance, insurance requirements, and project approvals, reducing the risk of non-conforming installations and expediting inspection sign-offs in regulated environments.
Eaton provides a limited lifetime warranty for CVS3175LL3, offering long-term protection against defects and enabling predictable maintenance budgeting. The combination of durable construction, code-compliant ratings, and reliable performance reduces replacement frequency and maintenance costs, improving total cost of ownership for critical power protection in automated facilities.
