Eaton SPD100480D3K Surge Protection Device - UL 1449
Part Number: SPD100480D3K
Quick Summary
Eaton SPD100480D3K surge protection device safeguards 480V delta motor control and distribution panels from transient surges. This helps prevent nuisance trips, equipment damage, and unplanned downtime by clamping voltage spikes before they reach sensitive loads. UL 1449-listed performance supports safety and compliance in industrial environments, while a rugged NEMA 1 enclosure and external sidemount design simplify installation. With a 15-year warranty, this SPD becomes a reliable cornerstone of protection strategies that reduce maintenance costs and extend equipment lifespans.

The SPD100480D3K delivers a robust 100 kAIC interrupt rating, which directly translates to fewer surge events reaching downstream devices, reducing motor and controller wear and lowering repair costs across manufacturing lines. This translates into measurable uptime gains and a lower total cost of ownership for critical equipment like drives and PLCs. Its 480V delta (3W+G) configuration ensures compatibility with common industrial power architectures, enabling straightforward integration with existing panels and switchgear. The external sidemount, NEMA 1 enclosure streamlines installation, minimizes footprint, and allows easier service access in busy plant environments. Standard feature package plus a surge counter provides immediate event visibility for traceability and regulatory reporting, supporting compliant maintenance programs. The 15-year warranty further protects capital investment and stabilizes budgeting for protection strategies across plant sites.
