Surge current
100 kA per phase
100 kA per phase surge rating is designed to handle high-energy transients, delivering immediate system protection and reducing unwanted outages. This translates to lower maintenance costs and fewer drive faults in production lines, especially where motors and drives share a bus. It is well-suited for 480V delta systems feeding switchgear and panel boards. The 480 Delta (3W+G) configuration ensures compatibility with common three-phase systems plus ground, enabling straightforward integration with existing equipment and simplifying commissioning. UL 1449 certification provides independent verification of protection performance, streamlining compliance audits and supplier qualification. The compact footprint—3.48 in depth, 7.47 in width, 12.05 in height—and a weight of 6.8 lb support space-efficient installation in crowded panels, reducing enclosure modification needs. Power Xpert SPD accessories and full PRL family compatibility ensure easy upgrades and seamless integration with switchboards, busways, and panel boards (PRL1a, 2a, 3a, 3e, 4).

FAQs
Install the SPD100480D4C within protected enclosures that serve 480V delta systems, ensuring it aligns with the panel’s busway entry points and mounting provisions. Verify 3W+G configuration, connect line and neutral/ground per Eaton installation guidelines, and maintain clearances for thermal dissipation. Use the Power Xpert SPD interface when integrating with existing protection schemes.
100 kA per phase indicates the device can safely absorb a high-energy surge on each of the three phases without damage or nuisance tripping. This rating correlates to better protection for drives, motors, and sensitive electronics in demanding industrial environments, reducing the likelihood of insulation breakdown and downtime during transient events.
Yes, the SPD100480D4C is designed for integration with Eaton Power Xpert SPD systems. It supports switchboards, busways, and panel boards, including configurations PRL1a through PRL4, enabling scalable protection across multiple bus architectures and simplifying future expansions.
SPD100480D4C is UL 1449 listed, confirming adherence to recognized surge protection performance standards. This certification supports compliance audits, procurement qualification, and reliability expectations for electrical protection schemes in industrial facilities.
The device reduces downtime by preventing transient-induced failures in critical equipment such as motors and drives. With UL 1449 protection and Power Xpert compatibility, maintenance is streamlined, inspection cycles are predictable, and the system life is extended, delivering a favorable total cost of ownership in facilities with high surge exposure.
