Eaton SPD100240D1Q Surge Protection Device - UL 1449
Part Number: SPD100240D1Q
Quick Summary
The Eaton SPD100240D1Q surge protection device delivers reliable surge suppression for 240V delta power systems in industrial distribution panels. In many facilities, transient surges from motors, drives, and switching events drive unplanned downtime and component wear. This unit is UL 1449 listed and housed in a rugged NEMA 4X stainless steel enclosure with external side mounting, offering long-term protection in demanding environments. It features a 100 kAIC interrupt rating and 320 V-L-G / 320 V-L-L operating voltages, giving engineers confidence in protecting critical loads. By combining robust protection with a 15-year warranty, the SPD reduces maintenance costs and asset downtime. Use this SPD alongside standard protection schemes to improve reliability, compliance, and overall energy-system resilience.

FAQs
The SPD100240D1Q uses external side mounting with a NEMA 4X stainless steel enclosure. This sidemount configuration facilitates retrofits and keeps protection hardware outside the energized equipment, aligning with the installation guidance in Eaton IM01005031E and the sidemounted SPD documentation.
Key specs include a 100 kAIC interrupt rating, 240V delta (3W+G) service, and operating voltage of 320 V-L-G and 320 V-L-L. These ratings ensure robust protection for industrial feeders, motor drives, and control panels against transient surges.
Yes. The device’s NEMA 4X stainless steel enclosure provides weather and corrosion resistance, enabling outdoor and damp-location deployments in accordance with UL 1449 requirements.
The SPD100240D1Q is UL 1449 listed and backed by a 15-year warranty, with a basic feature package included. This combination supports compliance reporting and long-term equipment protection without frequent replacements.
By protecting critical loads from surges, reducing unplanned downtime, and extending the life of downstream equipment, the SPD100240D1Q offers favorable total-cost-of-ownership. The 15-year warranty further enhances ROI through predictable maintenance planning and safer, longer-lasting power circuits.
