Eaton SPD100480Y2P Surge Protection Device - UL 1449
Part Number: SPD100480Y2P
Quick Summary
Surge Protection Device from Eaton SPD100480Y2P guards electrical systems in industrial power distribution. It is designed to absorb transient voltages and divert surges away from critical equipment, reducing the risk of failure and costly downtime. This model is UL 1449 listed and comes in a rugged NEMA 4X stainless steel enclosure, suitable for wet or harsh environments. The external sidemount configuration simplifies installation adjacent to switchgear or distribution panels and supports a 277/480V wye system. With a 100 kAIC interrupt rating and a broad 320 L-N, L-G, N-G, and 640 L-L operating range, it offers robust protection while enabling efficient retrofits. For buyers, the combination of performance, durability, and a 15-year warranty translates into predictable total cost of ownership and improved system reliability.

High-energy surge protection with a 100 kAIC interrupt rating is engineered to clamp transient events quickly, reducing gear wear and unplanned outages. The business impact is lower maintenance costs and extended downstream equipment life across motors, drives, PLCs, and switchgear. This is particularly valuable in 277/480V systems where mixed feeders are common and downtime directly impacts production efficiency. The stainless steel, NEMA 4X enclosure resists corrosion and is suitable for washdown areas and outdoor installations, dramatically reducing service calls and protecting the protection device itself from harsh environments. External sidemount mounting simplifies retrofits and on-site wiring, enabling faster project deployment and easier future service. The broad voltage range—277/480V wye with 320 L-N, 320 L-G, 320 N-G, and 640 L-L—ensures universal protection across varied feeders and equipment configurations, supporting scalable, future-proof installations. A 15-year warranty reinforces lifecycle value, delivering long-term cost of ownership relief and predictable budgeting for industrial protection strategies.

FAQs
External sidemount installation requires mounting adjacent to electrical distribution equipment with adequate clearance for wiring, service access, and heat dissipation. Ensure the enclosure remains weather-protected and that cables are routed to minimize bending and electrical noise. Verify compatibility with existing gear and leave space for future expansion or maintenance access, leveraging the robust NEMA 4X enclosure for harsh environments.
The unit protects 277/480V wye systems with a 100 kAIC interrupt rating. It supports 320 V-class line-to-neutral and line-to-ground voltages (320 L-N, 320 L-G, 320 N-G) and up to 640 V line-to-line (L-L). This broad operating range accommodates mixed feeders and supports reliable surge containment across industrial power distribution and motor control centers.
Yes. The device is housed in a stainless steel, NEMA 4X enclosure designed to withstand washdown, moisture, and environmental exposure. It carries UL 1449 listing, providing confidence in transient suppression performance and compliance with critical electrical protection standards, making it suitable for outdoor installations and demanding facilities.
The SPD100480Y2P is backed by a 15-year warranty, which helps reduce total cost of ownership. With a durable enclosure and proven surge suppression performance, routine maintenance typically centers on inspection during scheduled outages rather than frequent component replacement, supporting higher equipment availability and lower lifecycle costs.
The SPD100480Y2P is designed for external sidemount installation alongside electrical distribution equipment, easily coordinating with other protective devices. Its wide voltage compatibility and UL-listed ratings enable straightforward retrofit into current protection schemes, supporting coordinated protection strategies for panels, drives, and switchgear while minimizing wiring complexity.
