With a 50 kAIC surge rating, the CVX050-480D withstands major transient events, protecting sensitive drives and motors. This directly reduces unplanned downtime and extends the life of power electronics and control systems. In manufacturing and processing environments, that translates to fewer maintenance spikes and more predictable uptime for critical lines. Voltage compatibility across 380–480 V three-phase supplies ensures easy integration with existing feeders and equipment, reducing engineering time and avoiding unnecessary protective device substitutions. Applied to panelboards and motor control centers, it aligns with common industrial power architectures, enabling rapid, code-compliant deployments. Ground protection is included to provide a reliable fault path for surge energy, enhancing safety and equipment protection. The compact footprint and light weight—3.55 in L, 4.75 in W, 5.67 in H and about 2 lb—facilitate dense panel layouts and faster installations. Included grounding simplifies wiring and improves overall protection performance in automated facilities. Certification to UL 1449 and a 5-year warranty give procurement teams confidence in ongoing compliance and lifecycle reliability. Three-phase, three-wire configuration supports standard motor drives and distribution schemes, making retrofits or new installs straightforward in both Eaton and third-party panels.

FAQs
Install CVX050-480D in a suitable panel that supports 380–480 V three-phase systems. Ensure proper panel clearance, secure mounting to standard patterns, and correct grounding as instructed in the Eaton specification sheet. Use correct torque on terminals, maintain adequate ventilation, and verify that the device sits within the panel’s rated temperature range to sustain performance under surge events.
Key specs include a 50 kAIC surge rating, voltage tolerance across 380 V, 400 V, 415 V, 440 V, and 480 V, and three-phase operation. The device is UL 1449 listed and weighs about 2 lb with dimensions of 3.55 in L x 4.75 in W x 5.67 in H. It includes a ground connection and is designed for panelboard and motor drive protection in industrial environments.
CVX050-480D uses standard three-phase, three-wire protection suitable for many panelboards and motor control centers. Its compact footprint and universal mounting pattern simplify retrofits into both Eaton and compatible third-party panels. Always verify panel manufacturer guidelines and confirm space for installation, wiring clearance, and proper grounding as part of the integration process.
The CVX050-480D is UL 1449 certified, ensuring compliance with mainstream surge protection safety standards. It carries a 5-year manufacturer's warranty, providing long-term protection against device failure and predictable maintenance planning for industrial installations.
By limiting transient overvoltages, CVX050-480D reduces unplanned downtime, protects motors and drives, and extends component life. Although initial cost is higher than basic fuses, the savings from fewer outages, reduced replacement parts, and improved uptime typically yield a favorable ROI over the equipment lifecycle, especially in high-availability manufacturing and data-center environments.
