FAQs
The SPD080480D2N is designed for external sidemount installation on NEMA 4X enclosures. Follow the Eaton installation manual to mount in a sidemount position, ensure proper clearance for airflow, and connect to the 480V delta supply (3W+G). Use compliant conductors and secure with approved fittings. External mounting reduces cabinet intrusion and speeds retrofits in existing systems.
This device delivers an 80 kAIC interrupt rating for high-energy transients and is specified for 480V delta systems with operating voltages 640 L-G and 640 L-L. It is UL 1449 listed and designed to safeguard motor drives, panels, and distribution equipment from damaging surges common in industrial environments.
Yes. The unit uses a rugged NEMA 4X enclosure suitable for damp, dusty, and outdoor conditions. Its external sidemount capability allows installation outside standard equipment bays, providing robust protection for critical loads such as drives and control panels in challenging plant environments.
By limiting transient overvoltages, the SPD reduces capacitor bank and drive failures, lowers maintenance costs, and minimizes downtime. With an 80 kAIC rating and UL 1449 certification, the protection extends equipment life and stabilizes power quality, delivering measurable uptime gains and lifecycle cost savings.
