FAQs
The SPD100208Y1O uses external side mounting, designed for straightforward installation beside or on the exterior of electrical distribution equipment. It requires a standard 120/208V wye connection (4W+G) and should be wired to provide L-N, L-G, N-G, and L-L protection paths as per Eaton installation instructions.
SPD100208Y1O delivers a 100 kAIC interrupt rating, supports 120/208V wye systems, and is listed under UL 1449. It comes with a basic feature package and uses an external side mounting configuration to simplify integration in existing gear.
Yes. The device is housed in a NEMA 4X enclosure, providing rugged environmental protection suitable for outdoor or washdown areas. This makes it appropriate for industrial panels exposed to dust, moisture, and temperature variations while maintaining protection of internal components.
SPD100208Y1O is UL 1449 listed, signifying compliance with essential surge protection safety standards. The combination of UL listing, NEMA 4X enclosure, and a 15-year warranty supports reliability, compliance, and a lower total cost of ownership for medium- to high-demand electrical installations.
By mitigating transient events, SPD100208Y1O reduces the likelihood of equipment damage, extending life for transformers, drives, and PLCs. The 15-year warranty and durable enclosure translate to lower maintenance costs and improved uptime, delivering a favorable return on investment for critical manufacturing and process environments.
