FAQs
SPD100480Y4N is designed for use in NEMA 4 rated enclosures and supports 277/480 V Wye configurations with a 4W + Ground connection. The device integrates with Power Xpert SPD systems, enabling straightforward installation in protected industrial panels and outdoor or harsh environments without compromising access to the protection circuitry.
The unit delivers up to 100 kA per phase surge capability, absorbing transient voltages before they reach sensitive drives, PLCs, and automation controllers. This reduces the risk of component damage, minimizes outages, and lowers maintenance costs by preventing repeated surge events from propagating through the control system.
This device is well-suited for industrial panels, motor drive stations, and utility rooms across manufacturing, facilities, and process environments. It complements Power Xpert SPD installations, supports 277/480 V distribution, and provides reliable protection for equipment inside NEMA 4 enclosures where weather and washdown exposure are concerns.
SPD100480Y4N carries UL 1449 certification, a key standard for surge protection devices, ensuring performance and safety. Its enclosure rating (NEMA 4) further ensures suitability for damp and outdoor environments. Together, these certifications support regulatory compliance, safer installations, and documented protection performance for critical processes.
By suppressing transient surges effectively, the SPD minimizes repetitive stress on electrical components, reducing unplanned downtime and extending the life of drives and controllers. Its robust enclosure, standardized wiring, and Power Xpert compatibility simplify maintenance, facilitate faster replacements, and lower long-term ownership costs for industrial facilities.
