Eaton SPM100480Y4R Surge Protection Device - UL 1449
Part Number: SPM100480Y4R
Quick Summary
Surge Protection Device protects electrical systems from transient overvoltages in industrial facilities and data centers. This solution addresses nuisance outages and equipment damage by clamping surges before they reach critical loads, helping maintain production continuity. UL 1449 listing and a NEMA 4 enclosure provide rugged protection in demanding environments, while 277/480 V operation supports a wide range of industrial feeders. By integrating with Eaton’s Power Xpert SPD ecosystem, it offers predictable protection, simplified procurement, and long-term total cost of ownership benefits for electrical teams and maintenance programs.

High surge capacity delivers up to 100 kA per phase for 277/480 V Wye systems, protecting critical loads and reducing unplanned downtime in manufacturing lines and data centers. The business impact is clear: extended equipment life, fewer outages, and lower replacement costs. The SPD MAX design also supports scalable protection architecture, enabling straightforward upgrades as facilities grow. In terms of installation, the NEMA 4 enclosure with an internal circuit breaker simplifies mounting in harsh environments and reduces panel footprint concerns on shop floors. Compatibility with the Power Xpert SPD family ensures a cohesive protection strategy across Eaton’s electrical protection portfolio, easing procurement and spare parts planning for maintenance teams. This approach aligns with industry best practices for compliance and operational reliability, addressing common objections about retrofit readiness and integration complexity. Industry-specific insight shows that 100 kA per phase protection is increasingly standard for critical loads, making this device a prudent choice for data centers, manufacturing lines, and process control systems.

FAQs
The SPM100480Y4R is designed for 277/480 V Wye networks and ships in a NEMA 4 enclosure with an internal circuit breaker. Plan for a 15 inch width, 17.05 inch height, and 9.5 inch depth footprint, allowing upright mounting in switchgear rooms, mechanical spaces, or protected outdoor locations. Ensure proper clearance for heat dissipation and verify alignment with the Power Xpert SPD ecosystem for seamless integration and field service access.
A 100 kA per phase rating provides robust protection against high-energy transients, reducing the likelihood of downstream equipment damage during lightning events or switching surges. This translates into lower maintenance costs, less downtime, and improved uptime for critical loads such as servers, PLCs, drives, and motors commonly found in data centers and production lines.
Yes. The SPM100480Y4R is part of Eaton’s SPD MAX family and is designed for easy integration with the Power Xpert SPD ecosystem, enabling standardized protection across Eaton devices. This compatibility simplifies procurement, improves spare-part availability, and supports a cohesive protection strategy for multi-site facilities.
The device carries UL 1449 listing for surge protection devices and a NEMA 4 enclosure rating, suitable for both indoor and outdoor installations in demanding environments. These certifications help ensure regulatory compliance and reliable performance in harsh industrial settings.
Adopting the SPM100480Y4R can shorten downtime and extend the life of feeders, drives, and servers by mitigating transient overvoltage events. While initial costs include procurement and installation, the long-term savings come from reduced repair/replacement costs, fewer outages, and improved process reliability—key drivers of a favorable return on investment in manufacturing and data-center environments.
