FAQs
Begin by confirming a 230/400V Wye configuration and ensure the panel enclosure is rated NEMA 4. Mount the unit in a suitable slot, connect conductors per the terminal layout, and verify the internal disconnect is accessible. After wiring, test the device for operation and confirm UL 1449 labeling is visible for regulatory traceability.
The device is rated for 230/400 V Wye (4W+G) operation and provides 100 kA per phase surge current, delivering robust transient protection for motor drives, PLCs, and other sensitive equipment commonly found on 3-phase industrial networks.
It carries UL 1449 certification for surge protection performance and is housed in a NEMA 4 enclosure with an internal disconnect, enabling reliable field service in harsh or outdoor environments while maintaining code compliance.
Yes. The SPD100400Y4O is compatible with Eaton’s Power Xpert SPD ecosystem, allowing centralized protection coordination, easier monitoring, and scalable deployment across multiple panels or machines within a single protection framework.
By limiting transient overvoltage events, the SPD reduces component stress on drives and controllers, lowers maintenance costs, and minimizes unplanned downtime, leading to improved uptime metrics and longer asset life in manufacturing or processing facilities.
