Eaton SPD100480Y4A Surge Protection Device - UL 1449
Part Number: SPD100480Y4A
Quick Summary
SPD100480Y4A is a surge protection device designed to shield electrical distribution systems from transient overvoltages in commercial and industrial panels. In practice, engineers face downtime and equipment wear when surges slip past protections, leading to costly repairs and production interruptions. This unit carries UL 1449 protection and is compatible with 277/480 V Wye configurations, including direct bus mounted panel boards. With Power Xpert SPD integration, it streamlines protection across PRL1a, PRL2a, PRL3a, and PRL3e installations. Its compact footprint and straightforward mounting support faster commissioning, while delivering reliable, standards-compliant surge defense that aligns with maintenance workflows and compliance demands.
