Eaton SPC050480Y4P Surge Protection - NEMA 4X/UL 1449
Part Number: SPC050480Y4P
Quick Summary
The Eaton SPC050480Y4P surge protection device protects industrial electrical systems from transient spikes in panel and equipment. These surges can cause nuisance trips, premature component wear, and unplanned downtime, driving maintenance costs higher. UL 1449 listing and a NEMA 4X enclosure, along with a 277/480V Wye rating, ensure robust safety and reliable operation in harsh environments. Externally mounted and backed by a 10-year warranty, it provides predictable protection with easy integration into existing panels, improving uptime and long-term total cost of ownership. This combination supports compliance programs while simplifying procurement for engineers and maintenance teams across manufacturing, data centers, and processing facilities.

FAQs
The SPC050480Y4P is designed for external side mounting on standard electrical panels. Plan for a 277/480V Wye supply and wire the Form C relay for remote signaling or alarms. The NEMA 4X enclosure provides weather resistance, so ensure adequate clearance for service and heat dissipation in panel areas or outdoor cabinets.
It delivers up to a 50 kA surge current rating for 277/480V Wye systems. This level of protection clamps transient voltages before they reach downstream components, reducing stress on drives, PLCs, and power supplies. The device includes UL 1449 listing and a Form C relay for signaling.
Yes. The device uses a NEMA 4X enclosure suitable for washdown and outdoor installations, and its 277/480V rating matches common industrial feeders. With a 10-year warranty, it provides long-term protection against surges in demanding environments like automotive, food & beverage, and process plants.
The SPC050480Y4P carries UL 1449 certification and uses a NEMA 4X enclosure for rugged service. This combination ensures safety and reliability in harsh environments. Verify regional compliance for international installations, as CE or other marks are not specified in the provided data.
By limiting transient overvoltages, it minimizes nuisance tripping and wear on downstream equipment, extending life of switches, drives, and sensors. The 10-year warranty reduces replacement costs, and the Form C relay enables early fault notifications to control systems, supporting proactive maintenance programs and improved uptime.
