Eaton SPD080480Y2O Surge Protection Device - UL 1449 80 kAIC
Part Number: SPD080480Y2O
Quick Summary
SPD080480Y2O surge protection device protects industrial electrical systems from transient surges in distribution panels and equipment. By mitigating fast rising spikes, it helps prevent voltage-related damage to drives, PLCs, and motors. The challenge many plants face is unpredictable surges from faulty wiring, switching events, or utility disturbances that lead to unplanned downtime. This unit is UL 1449 listed and housed in a rugged NEMA 4X enclosure with an external sidemount for flexible installation in compact spaces. Its 320 L-N and 640 L-L protection, plus 277/480V wye ratings, deliver reliable protection across the most common industrial feeders. With a 15-year warranty, it reduces lifecycle costs, while compatible with standard SPD installations and Eaton's broader protection ecosystem.

FAQs
Installers should use the external sidemount configuration and follow Eaton’s installation manual to position the SPD adjacent to the distribution equipment. Verify clearance for 9.5 in length and the 5.4 in width, connect to 277/480V wye circuits, and ensure proper grounding. The device is designed for quick integration with standard SPD packages.
SPD080480Y2O offers an 80 kAIC interrupt rating and protection across 320 V line-to-neutral, 320 V line-to-ground, 320 V neutral-to-ground, and 640 V line-to-line. It is UL 1449 listed and rated for 277/480V wye systems, making it suitable for common industrial feeders and equipment.
Yes. The unit uses a NEMA 4X enclosure and is designed for external sidemount installation, delivering reliable protection in outdoor or harsh indoor environments. Its rugged construction helps withstand dust, water, and other challenging industrial conditions while maintaining performance.
By reducing surge-induced equipment damage and downtime, SPD080480Y2O lowers maintenance costs and extends the life of drives, PLCs, and motors. The 15-year warranty further reduces lifecycle risk, supporting a favorable total cost of ownership in facilities with frequent electrical disturbances.
Best suited for electrical distribution panels, machine centers, drives, PLCs, and control panels operating at 277/480V, particularly in environments with high transient activity. It is also advantageous for outdoor substations or areas with exposure to weather, vibration, and moisture where robust protection is required.
