Eaton SPD080400Y1Q Surge Protection Device - UL 1449

An 80 kAIC interrupt rating is engineered into the SPD080400Y1Q, delivering robust surge suppression for high-energy transients. The immediate business impact is a reduced risk of damage to transformers, drives, and control electronics, minimizing downtime and costly repairs in busy manufacturing cells. This capability is especially valuable for motor drives, CNCs, and PLC cabinets where a single surge event can halt production. The device supports 230/400V wye operation with four paths (L-N, L-G, N-G, L-L), ensuring comprehensive protection across all conductors. The business impact is consistent protection regardless of wiring configuration, simplifying design and accelerating compliance checks. In practice, it safeguards panelboards and switchgear in data centers, factories, and distribution rooms. External side mounting enables installation outside the main distribution equipment, reducing space inside panels and allowing retrofits without large enclosure changes. This simplifies upgrades and reduces installation time, which translates to lower labor costs and faster project commissioning. NEMA 4X stainless steel enclosure provides weather, corrosion, and washdown resistance, expanding the range of installation environments. For outdoor or damp facilities, the enclosure maintains performance and reduces enclosure-related maintenance. A Basic feature package keeps upfront costs predictable while delivering essential protection. Paired with UL 1449 certification, a 15-year warranty, and Eaton engineering support, this model balances risk management with total cost of ownership in new builds and retrofit projects. Compact form factor and clear operating voltage specs (320 L-N, 320 L-G, 320 N-G, 640 L-L) support straightforward integration with existing power distributions, helping engineers meet safety standards without compromising space.
