Eaton SPD100480D1O Surge Protection Device - UL 1449
Part Number: SPD100480D1O
Quick Summary
SPD100480D1O is a surge protection device that safeguards 480V delta (3W+G) electrical systems in industrial facilities. Engineers often contend with costly downtime when transient surges damage motors, drives, or control gear, and the SPD100480D1O helps prevent that by clamping spikes at the source. UL 1449 listed with a rugged NEMA 4X enclosure provides durable protection for both indoors and harsh outdoor environments. Its external side-mount design aligns with common panel layouts, and the 9.5 inch length keeps installation simple in crowded electrical rooms. Together with a 15-year warranty and the SPD series family of products, it supports reliable protection while reducing maintenance costs for industrial facilities.
