Eaton SPD100480D3N Surge Protection Device - UL 1449

High-energy protection with a 100 kAIC interrupt rating provides confidence against large surge events, minimizing downstream damage and enabling safer operation of feeders and protection panels in manufacturing lines. This translates to reduced unplanned downtime and lower warranty and repair costs for industrial equipment. In 480V delta systems, the SPD100480D3N delivers reliable clamping of transients on both phase-to-ground and phase-to-phase paths, protecting motors, drives, and control cabinets during voltage spikes. The rugged NEMA 4X enclosure supports indoor and outdoor installations, delivering weather resistance and corrosion protection for harsh environments. External side mounting simplifies retrofits and field installations, saving time and reducing the need for disassembly of existing distribution equipment. The standard feature package includes a surge counter, enabling proactive maintenance planning and performance tracking, which supports a lower total cost of ownership. With 640 L-G and 640 L-L operating voltages, the device aligns with common industrial power networks, promoting compatibility with a wide range of switchgear and panels. A 15-year warranty adds long-term value and confidence for capital projects and ongoing uptime initiatives.
