FAQs
SPD080480Y3Q is designed for 277/480V wye four‑wire systems (4W+G) and uses external side mounting for straightforward integration beside distribution gear. Its stainless steel NEMA 4X enclosure supports indoor or outdoor installations in challenging environments. The design minimizes wiring complexity and simplifies retrofit projects for new builds and plant upgrades, ensuring compliance with typical facility electrical protection schemes.
With an 80 kAIC interrupt rating, SPD080480Y3Q protects critical loads across L-N, L-G, N-G, and L-L paths. This capability guards motor starters, drives, panels, and control circuits from damaging transients, reducing unplanned downtime and extending equipment life in manufacturing lines and data centers.
Yes. The device uses a stainless steel, NEMA 4X enclosure and external side mounting, enabling reliable operation in damp, dusty, or outdoor locations. Coupled with UL 1449 listing, it provides verified protection without requiring extensive enclosure upgrades, making it suitable for plant yards, outdoor distribution panels, and harsh industrial environments.
Installers should plan for external side mounting near the electrical distribution equipment and route conductors to the surge protection module. The SPD includes a surge counter for maintenance reviews, and it carries a 15-year warranty. Regular checks of surge events help verify ongoing protection and assist in regulatory compliance reporting.
The SPD minimizes downtime, reduces unplanned maintenance, and extends the life of downstream equipment, delivering measurable total cost of ownership reductions. In facilities with high transient activity, the 80 kAIC protection plus a long warranty translates to quicker amortization and improved reliability metrics in CAPEX justification.
