Eaton CVX050-480Y Surge Protection Device - UL1449
Part Number: CVX050-480Y
Quick Summary
The Eaton CVX050-480Y surge protection device safeguards three-phase electrical systems from transient surges. Power quality events and mis-sized protection cause expensive downtime; selecting the right SPD is essential. UL 1449 listing with a 5-year warranty and a three-phase design provide reliable compliance and long-term value. This solution aligns with energy-management goals and supports quick deployment in 220/380 to 277/480 V environments. Beyond protection, it integrates with standard panel wiring for straightforward installation and maintenance, and engineers value its compact 2 lb form factor. In practice, it helps protect costly motors, drives, and controls from sporadic surges that accompany switching events.

Feature: 50 kAIC surge current rating with UL 1449 listing. Business Impact: This level of transient protection minimizes the risk of equipment damage during line disturbances, reducing repair costs and unplanned downtime. Application: Ideal for panelboards and machine-automation lines across manufacturing environments. Field engineers report fewer service calls after upgrading to CVX050-480Y due to consistent surge suppression. Feature: Three-phase voltage ratings spanning 220/380 V, 230/400 V, 240/415 V, and 277/480 V. Business Impact: Directly matches common industrial power systems, simplifying design, procurement, and installation. Application: Suitable for OEM equipment, process lines, and distribution panels in mixed-voltage facilities. This reduces design complexity in multi-source facilities. Feature: Compact enclosure with dimensions around 3.55 in by 4.75 in by 5.67 in and a weight of 2 lb. Business Impact: Easier mounting in crowded control panels and faster service with minimal space penalties. Application: Retrofit projects and new installations where space is a premium, including compact switchgear housings. The small form factor supports efficient heat management and IP-rating considerations. Feature: Comprehensive protection paths including L-L, L-N, L-G, and N-G configurations. Business Impact: Delivers robust protection against line-to-line and line-to-ground surges, reducing nuisance trips and device wear. Application: Protects CNCs, robotics, drives, and other sensitive automation equipment. This broad coverage also simplifies integration with existing protection schemes. Feature: Five-year warranty and UL 1449 certification backing reliability. Business Impact: Lowers total cost of ownership through extended coverage and consistent performance. Application: Asset-protection programs, predictive maintenance plans, and long-term protection strategies. Engineers appreciate the assurance of ongoing protection through planned maintenance cycles.
