Eaton’s SPD Series (Sidemount Versions) Data Sheet
The SPD100480Y2N offers a 100 kAIC interrupt rating, which translates to a strong defense against high-energy surges and a measurable reduction in unplanned downtime for critical loads like CNC machines or PLC-controlled conveyors. With 277/480V wye (4W+G) operation, the device is broadly compatible with typical industrial power distributions, enabling faster retrofits and fewer wiring changes during installation. The rugged NEMA 4X enclosure provides weather and environment resistant protection, delivering reliable operation in outdoor or damp facilities and lowering service calls. External side mounting simplifies installation outside electrical distribution equipment, reducing space constraints and labor costs during upgrades or expansions. UL 1449 listing confirms compliance with industry surge standards, while a 15-year warranty offers long-term asset protection. Together these features support lower total cost of ownership, improved plant reliability, and better protection for sensitive automation equipment.

FAQs
External sidemount installation is designed to simplify retrofits by placing the surge protection device outside the main distribution panel. Ensure there is accessible clearance for service and venting, confirm compatible mounting hardware, and verify that the external mounting location remains within the rated environmental conditions of the NEMA 4X enclosure. Proper wiring follows standard raceway routes to minimize voltage drop and maintain surge performance.
Key specs include a 100 kAIC interrupt rating, 277/480V wye (4W+G) voltage rating, external sidemount mounting, NEMA 4X enclosure, and UL 1449 certification. The device supports L-N, L-G, N-G, and L-L operating configurations with overall dimensions of 14 in (L) by 10 in (W) by 7 in (H) and a weight of 17.7 lb, providing robust protection for critical loads.
