Eaton SPD100208Y3K Surge Protection Device - UL 1449
Part Number: SPD100208Y3K
Quick Summary
SPD100208Y3K surge protection device protects 120/208V systems from transient surges in commercial and industrial panels. Outages and equipment damage drive downtime and maintenance costs, especially when devices are mounted externally to distribution gear. UL 1449-listed protection helps verify safety and performance, while a NEMA 1 enclosure and external sidemount design support rugged field deployment. This combination enables rapid installation, minimal panel disruption, and scalable protection with L-N, L-G, N-G, and L-L configurations, delivering long-term reliability for electrical contractors, OEMs, and facility managers.

FAQs
SPD100208Y3K is designed for external sidemount installation, allowing mounting on or adjacent to distribution equipment without opening the main panel. Follow IM01005031E and use L-N, L-G, N-G, L-L for proper surge routing. Ensure secure mounting to prevent vibration and service interruptions, and verify enclosure orientation during retrofit projects.
Key specs include a 100 kAIC interrupt rating, 120/208V wye configuration, NEMA 1 enclosure, external side mounting, and a standard feature package with a surge counter. Operating voltages are 150 L-N, 150 L-G, 150 N-G, and 300 L-L, making it suitable for 3-phase commercial and light industrial systems.
Yes, SPD100208Y3K is UL 1449 certified, which confirms safety and performance under transient events. This UL listing supports documentation for compliance during commissioning and ensures compatibility with external sidemount installations in NEMA 1 enclosures.
Applications include commercial buildings, data centers, and manufacturing facilities needing reliable surge suppression for motors, drives, and sensitive electronics. The external sidemount design minimizes panel disruption, enables easy retrofit, and scales protection as load profiles grow, reducing downtime and protecting critical assets.
SPD100208Y3K carries a 15-year warranty and includes a surge counter to track performance over time. Maintenance is minimal—focus on periodic visual checks and confirming the external mount remains secure. This combination supports lower total cost of ownership and clearer ROI for procurement and facilities teams.
