Eaton SPD100400Y2N Surge Protection Device - UL 1449
Part Number: SPD100400Y2N
Quick Summary
The Eaton SPD100400Y2N surge protection device protects electrical systems from transient overvoltages in industrial and commercial environments. When spikes ride along the grid or switching events occur, downtime and equipment damage cost time and parts, but this unit clamps surges at the source. UL 1449 listed protection and a rugged NEMA 4X enclosure ensure reliable performance in harsh environments. In addition to protection, the external side mounting and compact dimensions enable straightforward retrofits and scalable distribution layouts. Designed for 230/400V wye systems and 4-wire plus ground configurations, it supports common industrial controls and panel boards. With a 15-year warranty, 100 kAIC interrupt rating, and operating voltages 320 L-N, 320 L-G, 320 N-G and 640 L-L, it balances protection with cost efficiency.
