FAQs
Installation is designed to be straightforward for sidemount applications. Ensure correct clearance for the external side mount, connect L-N, L-G, N-G and L-L paths per the 277/480V wye system, verify the internal disconnect is accessible, and confirm UL 1449 compliance. Use the surge counter during commissioning to verify operation and record surge activity for maintenance logs.
Key specs include an 80 kAIC interrupt rating, 277/480V wye (4W+G), enclosure rated NEMA 4X, external side mounting, and operating voltages of 320 L-N, 320 L-G, 320 N-G, and 640 L-L. The device is part of Eaton’s SPD series and includes a standard feature package with a surge counter for monitoring.
Yes. SPD080480Y3O uses a NEMA 4X enclosure designed for weather resistance and washdown environments, making it suitable for outdoor installations and harsh indoor spaces. The external side-mount format also facilitates retrofits in existing outdoor or semi-exposed electrical distributions while preserving protection performance.
The unit comes with a 15-year warranty, reflecting long-term reliability. Maintenance benefits include the built-in surge counter for traceable surge history, enabling proactive replacement planning and simpler regulatory reporting. Routine checks should verify the protection status and ensure connections remain tight after environmental exposure.
UL 1449 listing provides recognized protection compliance, while the 80 kAIC rating and robust enclosure minimize unplanned downtime and equipment damage. The sidemount installation reduces retrofit complexity and labor costs, and the surge counter supports maintenance planning and regulatory documentation, contributing to lower total cost of ownership and faster return on investment.
