Eaton SPM100480Y3V SPD MAX series surge protector - NEMA 4X

Designed for 277/480V systems, the SPM100480Y3V supports 100 kA per phase with a compact single-module footprint in a 4-wire plus ground configuration. This high-energy rating translates into lower risk of downstream equipment damage during surge events, reducing unplanned downtime and extending the life of drives, soft starters, PLCs, and I/O modules. In mid- to high-voltage industrial environments, users typically see fewer nuisance trips and less wear on surge-sensitive components, delivering measurable uptime gains and improved process reliability. With a true NEMA 4X enclosure and internal circuit breaker, the unit can be mounted indoors or in exposed or harsh environments without requiring extra external protection. The integrated design simplifies wiring, labeling, and commissioning in electrical rooms, outdoor cabinets, or wash-down areas, and its 50 lb weight supports straightforward installation by a single technician with basic tools. The compact 9.3 in depth, 14.91 in width, and 17.5 in height balance protection capacity with panel space, enabling easier retrofits and future upgrades. Surge counter provides real-time awareness of surge activity, enabling maintenance teams to correlate events with equipment stress and justify part replacements. When combined with RoHS compliance and the listed certifications, the device supports audit readiness and procurement efficiency, reducing cycle times for compliance reviews and lowering the risk of non-conforming components entering critical power paths. Warranty coverage spans 15 years from delivery, or 20 years with registration, offering long-term financial protection against unplanned replacement costs. This aligns with asset-management strategies and total cost of ownership calculations for critical loads such as motors, drives, soft starters, and automation controllers, helping procurement justify the initial capital expenditure through predictable lifecycle cost savings. Best used where 277/480V distribution feeds motor drives, contactors, or switchgear, the SPM100480Y3V easily integrates with existing SPD inventories and protection schemes. Its single-module design simplifies stocking and replacement, while the internal monitoring features streamline testing routines during routine electrical preventive maintenance.
