FAQs
When installing SPD100400Y4J, plan for a clear mounting location within the MCC, allow adequate clearance for heat dissipation, and wire per 230/400 V Wye (4W+G) configuration. Use the Power Xpert SPD accessory for integrated protection and ensure proper conductor sizing and protective device coordination to meet UL 1449 requirements.
Key specs include a 100 kA per phase surge current rating and a 230/400 V Wye (4W+G) voltage rating. The high surge rating clamps transient voltages effectively, protecting motor starters and drives, while the 4W+G configuration supports both line and ground conductors for robust protection and safe dissipation of faults.
Yes. SPD100400Y4J is designed to integrate with Eaton’s Power Xpert SPD ecosystem, enabling a cohesive protection strategy across MCCs. Compatibility helps streamline procurement, simplifies maintenance, and ensures consistent protection levels across devices in a shared panel environment.
SPD100400Y4J carries UL 1449 certification, signaling compliance with recognized safety and performance standards for surge protection devices. This certification supports regulatory alignment, reduces auditing risk, and provides customers with assurance of proven protection for critical electrical infrastructure.
By limiting transient overvoltages, the SPD reduces insulation stress, minimizes premature component wear, and lowers unplanned downtime. The result is longer equipment life, fewer maintenance interventions, and a faster path to compliant, heat-tolerant protection in motor control centers, delivering tangible cost savings over time.
