With a 150 kAIC interrupt rating, the SPC150480Y7P clamps high-energy surges at the source, protecting downstream devices such as contactors, drives, and PLCs. This reduces catastrophic equipment failures and unplanned downtime, delivering measurable savings for high-availability lines. In applications like stamping presses and packaging lines, robust surge handling translates to improved uptime and lower asset life-cycle costs. Voltage rating of 277/480V Wye aligns with most industrial power systems, enabling straightforward integration into new builds and retrofits. The NEMA 4X enclosure provides moisture, dust, and corrosion resistance, making the unit suitable for outdoor cabinets and damp plant environments, simplifying compliance and reducing the need for extra weatherproofing. Filtering reduces transient noise and EMI, while the Form C relay enables alarms or interlocks for proactive maintenance and enhanced control reliability. External side mounting supports flexible retrofits in crowded panels, enabling quick installations with minimal wiring changes. The compact dimensions and 4 lb weight help preserve panel space, and the 10-year warranty lowers long-term maintenance concerns, creating a favorable total-cost-of-ownership profile for procurement teams.

FAQs
Installers should mount the SPC150480Y7P on the panel’s exterior side per Eaton’s guidance, ensuring proper clearance for wiring and ventilation. Connect 277/480V Wye conductors to the protected terminals, secure the unit with the included hardware, and route the Form C relay wiring to the control system. Verify tight torque on lugs and test with a protection device simulator to confirm proper operation before commissioning.
Yes. The SPC150480Y7P is designed for 277/480V Wye systems, facilitating seamless integration into existing industrial feeders and switchgear. Its NEMA 4X enclosure adds weather and environmental resilience, allowing installation in outdoor or harsh indoor locations without additional protective housings. External side mounting further simplifies retrofits by minimizing panel rework and wiring complexity.
The Form C relay offers a versatile, programmable signaling path for alarms, interlocks, or remote trip logic. This enables proactive protection strategies and easier integration with plant supervision and PLCs. In practice, teams can trigger maintenance alerts or interlock downstream equipment automatically when surge events exceed preset thresholds.
SPC150480Y7P is UL 1449 listed, ensuring conformity to established surge protection safety standards. It is housed in a NEMA 4X enclosure, providing robust protection against moisture, dust, and corrosion for rugged environments. The combination supports safer operation and streamlined compliance across industrial facilities and outdoor installations.
The 150 kAIC protection reduces the likelihood of expensive equipment failures and unplanned downtime, translating into shorter outages and increased throughput. Coupled with a 10-year warranty and lower maintenance costs due to integrated filtering and signaling, the device typically lowers total cost of ownership for modern, high-availability manufacturing environments.
