Eaton SPM300480Y4R SPD MAX Surge Protection - UL 1449
Part Number: SPM300480Y4R
Quick Summary
The Eaton SPD MAX surge protection device protects critical electrical systems from transient overvoltages across industrial power networks. Unprotected equipment leads to unexpected downtime, costly repairs, and brittle control systems when lightning surges or switching transients strike. UL 1449 listing and a rugged NEMA 4 enclosure deliver proven safety and durability, while the 277/480 V Wye rating ensures compatibility with common facility mains. Designed to integrate with Power Xpert SPD ecosystems, it offers reliable protection with straightforward installation and scalable monitoring, helping maintenance teams reduce total cost of ownership. This combination supports risk-based maintenance programs and improves uptime across critical production lines.
