Special features
Standard with surge counter
Feature → Business Impact → Application: 300 kA per phase surge capacity provides robust protection for critical loads, reducing the risk of downstream equipment damage and unplanned downtime in manufacturing lines and data centers. This translates to measurable uptime gains and lower maintenance costs, especially where high-energy transients are common. Application: large machine cells and critical power feeders that require dependable surge mitigation and quick fault isolation. Feature → Business Impact → Application: 277/480 V Wye (4W+G) compatibility enables seamless integration with standard industrial power distribution, reducing retrofit time and minimizing wiring changes. Application: retrofit projects on existing 277/480 V systems in factories and distribution centers. Feature → Business Impact → Application: NEMA 4X enclosure with internal circuit breaker delivers rugged outdoor or harsh-environment protection while simplifying installation and maintenance, minimizing enclosure space needs and risk of weather-related issues. Application: outdoor substations, damp environments, or industrial exterior installations. Feature → Business Impact → Application: Standard surge counter supports proactive maintenance and compliance reporting, enabling operators to track surge events and schedule interventions before faults escalate. Application: audit trails for regulatory compliance and service planning. Feature → Business Impact → Application: 15-year warranty (20 years with registration) reduces total cost of ownership and provides long-term protection for mission-critical assets. Application: asset lifecycle planning for data centers and manufacturing lines. RoHS compliance further supports sustainability goals across plant operations.

FAQs
SPM300480Y1V is designed for 277/480 V Wye systems with a 4W+G configuration and integrates into standard industrial panels. It features an internal circuit breaker and a compact footprint, enabling straightforward retrofits. When planning installation, ensure conductor sizes meet the device’s surge and current ratings and verify enclosure clearance per NEMA 4X requirements.
A 300 kA per phase rating indicates the SPD can safely divert very high surge currents per phase without device damage, protecting downstream equipment and reducing risk of cascading failures. This rating supports protection for sensitive loads in demanding environments and aligns with industry safeguards for motors, drives, and control panels.
Yes. The device is housed in a NEMA 4X enclosure with an internal circuit breaker, designed for harsh or damp locations. This enables outdoor installations or spaces with exposure to moisture while maintaining protection integrity and minimizing exposure of external components to the elements.
The SPD carries CSA, UL 1449, and UL 1283 certifications, reflecting recognized safety and performance compliance. It is RoHS compliant, supporting environmental requirements. While data centers have additional IT and electrical considerations, this device meets core electrical protection standards and provides reliable surge mitigation as part of a broader compliance strategy.
The SPM300480Y1V carries a 15-year warranty from delivery, with a 20-year term available when registered on Eaton’s SPD site. This extended coverage lowers long-term maintenance costs, improves asset resilience, and supports ROI by reducing replacement frequency while offering predictable lifecycle planning for industrial power protection.
