Eaton SPD100480Y2Q Surge Protection Device - UL 1449

The SPD100480Y2Q utilizes a 100 kAIC surge capability and accepts 277/480V wye service, providing robust upstream protection. This translates to a measurable reduction in transient damage to drives, PLCs, controllers, and sensitive instrumentation, lowering repair costs and unplanned downtime across operations. It is well suited for electrical distribution panels in industrial facilities, data centers, and commercial buildings where reliable power conditioning is essential. External side mounting and NEMA 4X stainless enclosure deliver environmental resilience, enabling installation in exposed or challenging spaces without enclosure corrosion risk. The design simplifies retrofit into existing electrical distributions and minimizes enclosure-related maintenance. Ideal for outdoor equipment, plant entrances, and outdoor switchgear where space constraints and weather exposure demand robust protection. Operating voltage coverage of 320 L-N, 320 L-G, 320 N-G, and 640 L-L provides comprehensive phase-to-phase and phase-to-ground protection for four-wire systems. This breadth reduces the need for multiple adapters or devices, improving installation efficiency and compliance with utility or electrical codes. The combination of 4W+G configuration and external mounting supports flexible integration into new or retrofit projects. With a 15-year warranty and UL 1449 certification, the SPD series offers long-term reliability and predictable maintenance budgeting. The product ships with the standard feature package and installation resources, helping procurement teams avoid scope creep. In practice, embracing this device can lower lifecycle costs and safeguard uptime across critical process lines. Built for fast deployment, the SPD100480Y2Q aligns with Eaton's SPD series data sheets and installation instructions that cover external mounting to electrical distribution equipment. The datasheet and installation manual provide clear wiring, connection diagrams, and test procedures to minimize commissioning time. This reduces field service calls and accelerates time-to-protection for panel builders and electrical contractors. Industry workflows increasingly demand reliable, easy-to-install protection that does not disrupt production. The SPD100480Y2Q’s compatibility with external distribution equipment and straightforward wiring diagrams supports rapid commissioning, lowers risk during retrofit projects, and helps teams meet uptime targets across mixed industrial environments.
