Eaton SPC100480Y7P Surge Protection Device - UL 1449
Part Number: SPC100480Y7P
Quick Summary
Eaton SPC100480Y7P surge protection device protects industrial power systems from transient surges in 277/480V Wye networks. Without protection, equipment downtime, unexpected failures, and costly repairs from voltage spikes threaten production uptime. UL 1449 listing and a rugged NEMA 4X enclosure ensure rugged reliability, while a 100 kAIC interrupt rating guards critical loads. External side mounting and built-in filtering deliver practical business value for electrical infrastructure, helping facilities meet uptime and compliance goals while minimizing maintenance.

FAQs
The SPC100480Y7P is designed for external side mounting, allowing it to be installed on standard control panels or bus assemblies adjacent to the protected equipment. Verify a 277/480V Wye supply, connect line and load terminals per Eaton wiring diagrams, and secure the unit to a stable surface. Ensure enclosure integrity for NEMA 4X environments and test the integrated filtering and Form C relay signaling after commissioning.
This device offers a 100 kAIC interrupt rating, enabling it to withstand and divert large transient surges without compromising upstream equipment. By clamping surge energy and providing filtration, it minimizes voltage spikes reaching sensitive loads such as PLCs, drives, and controls, reducing nuisance trips and extending the life of downstream components.
Yes. With a 277/480V Wye rating, the SPC100480Y7P is well suited for three-phase industrial environments, including manufacturing lines and data centers that rely on higher-voltage distribution. Its filtering plus Form C relay provides reliable signaling for status monitoring and control integration, which helps maintain clean power and informed maintenance planning.
The SPC100480Y7P is UL 1449 listed and housed in a NEMA 4X enclosure. UL 1449 confirms surge protection performance to recognized standards, while NEMA 4X ensures weather and corrosion resistance in demanding environments. Together these certifications support regulatory compliance, safety, and longer service life in industrial facilities.
Expect low ongoing maintenance due to solid-state protection and a long 10-year warranty. By protecting critical loads from surges, you reduce downtime, prevent costly equipment replacements, and improve overall uptime metrics. The Form C relay also enables easy monitoring and alerts, supporting proactive maintenance and a favorable total cost of ownership.
