FAQs
Use external side mounting on 277/480V wye systems, with a stainless steel NEMA 4X enclosure. Connect the device to L-N, L-G, N-G, and L-L as specified, and utilize the internal disconnect for service isolation. Ensure proper busbar alignment and follow the installation manual for safe, compliant commissioning.
80 kAIC is the interrupt rating describing the maximum surge current the SPD can safely absorb without compromising protection. In facilities with 277/480V power, this rating indicates strong transient protection for downstream drives, motors, and controls, reducing the risk of component damage and unplanned downtime when surges occur.
Yes. The SPD080480Y1Q is designed for 277/480V wye systems and offers external sidemount installation with a durable NEMA 4X stainless enclosure. UL 1449 listing confirms compliance, making it appropriate for data centers and manufacturing lines that require reliable surge protection for critical automation loads.
UL 1449 listing confirms surge protection performance and safety compliance. The enclosure is rated NEMA 4X for protection against dust, water, and corrosion in challenging environments. The product’s rugged construction and warranty support long-term reliability and regulatory confidence for industrial applications.
The SPD has no moving parts, minimizing maintenance needs beyond periodic inspections. The 15-year warranty reduces lifecycle risk, while effective surge protection lowers downtime, extends equipment life, and improves ROI for automation projects and facility reliability programs.
