Special features
Basic
Feature → Business Impact → Application: 250 kA per phase surge protection on 277/480 V Wye networks provides strong transient defense, reducing risk of equipment damage and downtime in mission-critical applications such as data centers and manufacturing lines. This translates to higher uptime, fewer warranty claims, and lower replacement costs in high-energy environments. Feature → Internal circuit breaker within a NEMA 4 enclosure offers safe, weatherproof protection with reduced maintenance needs, enabling outdoor or harsh indoor installations and simplifying retrofits for existing panels. Feature → Single module, basic protection configuration supports compact, modular deployments; it scales across multiple outlets and feeders, decreasing panel congestion and enabling straightforward replacement when aging components are swapped. Feature → RoHS compliant with UL/CSA certifications ensures regulatory alignment and supply-chain confidence, simplifying spec approval and vendor management. Feature → 9.3 in depth, 17.5 in height, 14.91 in width, 50 lb weight provide predictable footprint for panel layouts and shipping logistics, improving on-site planning and standardization. Feature → 15-year warranty (20 years with registration) reduces total cost of ownership and supports long-term service agreements, reinforcing ROI for facilities relying on continuous protection of critical loads.

FAQs
The SPM250480Y1R is designed as a single-module protection device with a NEMA 4 enclosure and an internal circuit breaker, facilitating straightforward mounting and integration into 277/480 V systems. Verify panel space, ensure proper clearances for maintenance, and confirm compatibility with the SPD MAX family. Use appropriate enclosure knockouts and maintain a clean conductor routing to minimize heat build-up and ensure rapid response during surges.
The 250 kA per phase rating provides robust transient handling to absorb high-energy surges before they reach connected equipment. This level of protection helps prevent nuisance trips, reduces insulation stress on drives and controllers, and supports mission-critical equipment in manufacturing lines and data centers where electrical noise and surges are common.
Yes. The SPM250480Y1R is part of Eaton's SPD MAX family and is designed to integrate with other devices in the same protection strategy. This compatibility enables scalable protection across multiple feeders and panels, simplifying procurement, installation, and maintenance while maintaining consistent performance and certifications.
