FAQs
SPD100600D4O is designed for rugged industrial installations with a NEMA 4 enclosure and internal disconnect, simplifying outdoor or exposed mounting. Ensure alignment with 600 Delta (3W+G) system requirements and place protection as close to the point of entry as possible to maximize transient suppression. Verify clearance for maintenance access and follow manufacturer torque specs for all terminal connections.
100 kA per phase indicates the device can safely divert high-energy transient surges on each phase without failure. This rating is crucial for protecting high-current loads like motors and drives. For best results, match the surge rating to the largest anticipated surge level in the installation site and ensure proper wiring and enclosure integrity to maintain performance.
Yes. The unit’s NEMA 4 enclosure is designed for outdoor and harsh environments, providing moisture and dust resistance while housing the internal disconnect for safe maintenance. When planning outdoor deployment, consider routing, drainage, and proximity to other heat sources to maintain optimal operating temperature and longevity.
SPD100600D4O carries UL 1449 certification, a key standard for surge protective devices, ensuring performance and safety under transient events. The combination of UL listing and a NEMA 4 enclosure supports compliance during audits and procurement, reduces design risk, and simplifies installation in industrial facilities where regulatory adherence is essential.
