FAQs
SPD100400Y3O is designed for external sidemount installation, enabling easy placement adjacent to electrical distribution equipment. The rugged NEMA 4X enclosure supports both indoor and outdoor environments, and the external side mounting reduces internal footprint while simplifying wiring and inspection. This setup is ideal for panel modernization projects and retrofit installations in existing plant layouts.
Key specifications include a voltage rating of 230/400V wye (4W+G) and an operating voltage of 320 L-N, 320 L-G, 320 N-G, 640 L-L. The device provides a 100 kAIC interrupt rating, offering strong transient protection for critical loads such as drives, PLCs, and control cabinets in industrial environments.
Yes. The SPD100400Y3O is UL 1449 listed and housed in a rugged NEMA 4X enclosure, making it suitable for harsh industrial environments and outdoor installations. Its external sidemount design facilitates proximity to distribution equipment, reducing wiring length and improving protection for motor drives and automated equipment against transient events.
The device includes a standard feature package with a surge counter, enabling straightforward monitoring and compliance verification. The 15-year warranty supports long-term reliability and predictable maintenance planning, helping procurement teams justify the initial investment and integrate the SPD into preventive maintenance programs.
ROI stems from reduced downtime, fewer unplanned outages, and protection of expensive equipment like drives and PLCs. By limiting surge damage and extending asset life, facilities can lower repair costs, avoid production losses, and improve uptime metrics. The UL 1449 listing and warranty further strengthen asset resilience and total-cost-of-ownership benefits.
