Eaton’s SPD Series (Sidemount Versions) Data Sheet
High surge capability directly translates to reduced equipment damage and fewer unplanned outages; the 80 kAIC interrupt rating provides robust protection for motors, drives, and controllers in demanding environments. This SPD operates across 320 L-N, 320 L-G, 320 N-G, and 640 L-L voltages in a 277/480V wye system, enabling seamless integration into existing electrical distributions and minimizing retrofit costs. The external sidemount configuration simplifies installation, while the NEMA 4X stainless steel enclosure offers corrosion resistance and durable service in both indoor and outdoor settings. A built-in internal disconnect further streamlines maintenance, eliminating the need for separate enclosure access. With a standard feature package and UL 1449 compliance, you gain regulatory confidence and predictable performance for data centers, manufacturing lines, and process plants. This means lower lifecycle costs and improved uptime across your electrical protection strategy.

FAQs
Begin by locating the SPD in a suitable enclosure area and confirm the panel is rated for 277/480V with a 4W+G configuration. Mount the unit to the external sidemount per the IM01005031E instructions, connect L-N, L-G, N-G, and L-L conductors according to the wiring diagram, and secure the internal disconnect. Verify enclosure integrity and grounding before energizing. This approach minimizes panel space impacts while delivering reliable surge protection.
The 80 kAIC rating indicates the maximum short-circuit current the device can safely interrupt during a transient event without compromising protection or enclosure integrity. This level of protection is suitable for demanding industrial loads, reducing the likelihood of device failure and downtime when encountering large transient spikes from motors, drives, or utility events.
Yes. The NEMA 4X stainless steel enclosure delivers corrosion resistance and rugged protection suitable for indoor and outdoor service. External sidemount installation further eases retrofits in existing facilities, while UL 1449 certification confirms compliance with surge protection standards for reliability in harsh environments.
SPD080480Y2Q carries UL 1449 certification, a recognized standard for surge protection devices, and utilizes a NEMA 4X stainless enclosure for durable protection. These certifications help ensure regulatory compliance, safer operation, and consistent protection performance across industrial applications.
The 15-year warranty provides long-term assurance against failure and reduces replacement costs. With robust protection reducing downtime and extending equipment life, facilities typically see lower maintenance intervals and avoided production losses, leading to a favorable total cost of ownership for protection of critical loads in manufacturing, data centers, and process environments.
