FAQs
To install the SPD100480D4K, power down the panel and confirm a 480V delta (3W+G) configuration. Mount the device inside a NEMA 1 enclosure and connect the three line conductors to L1, L2, and L3 per Eaton’s installation guide. Ensure solid grounding, proper clearance, and secure terminal connections before reenergizing the system. Follow lockout/tagout procedures throughout.
The 100 kA per phase rating provides high-energy transient tolerance, reducing the risk of damage during large surges from switching, faults, or external events. This helps prevent downstream equipment failures in drives, PLCs, and motors, lowers nuisance tripping, and contributes to longer service life and lower maintenance costs in demanding manufacturing environments.
Yes. The SPD100480D4K is designed for indoor use in NEMA 1 environments and is UL 1449 listed, making it appropriate for standard electrical rooms and line-side protection in manufacturing facilities. Its rugged enclosure and Eaton compatibility support reliable performance in busy plant settings.
SPD100480D4K carries UL 1449 certification, signaling adherence to recognized safety and performance standards for surge protection devices. This certification simplifies procurement, supports audit readiness, and aligns with regulatory expectations for industrial electrical protection installations.
Implementing this SPD reduces unplanned outages and equipment replacement costs by limiting transient damage to critical loads. It requires minimal ongoing maintenance beyond periodic inspections. When combined with Eaton’s Power Xpert SPD ecosystem, you gain diagnostic visibility and easier fault isolation, improving maintenance efficiency and asset longevity.
