FAQs
Begin by confirming 480V delta (3W+G) operation and selecting a suitable external sidemount location on the panel. Mount the device on the exterior side, connect L1, L2, L3, and ground per the Eaton installation manual IM01005031E, and secure all cables with proper strain relief. Ensure the enclosure remains rated as NEMA 4X for protection during operation.
Key specs include a 100 kAIC interrupt rating, 480V delta (3W+G) voltage rating, and operating voltage of 640 L-G / 640 L-L. The device is UL 1449 certified and housed in a NEMA 4X enclosure, with a compact footprint of 9.5 in length, 5.4 in width, and a weight of 3.5 lb, suitable for sidemount installation.
This SPD is well suited for industrial control panels, outdoor distribution equipment, and manufacturing lines using 480V delta systems. Its sidemount external installation supports retrofit projects, while the 100 kAIC rating provides robust protection for critical drives, motors, and transformers against transient surges in harsh environments.
SPD100480D1N is UL 1449 certified and housed in a NEMA 4X enclosure, meeting common industrial protection standards. It carries a 15-year warranty, offering long-term reliability and assurance for maintenance budgets and compliance programs in facilities with stringent uptime requirements.
