With a 50 kA surge rating, this SPD clamps high-energy transients quickly to protect downstream devices. That rapid response reduces insulation stress on breakers, controllers, and sensors, lowering part failures and maintenance costs. It’s well suited for panel boards and feeders in automated manufacturing environments where uptime matters. Enclosure and mounting: The NEMA 4X enclosure and external side mounting simplify installation in harsh environments and retrofit projects. This construction resists moisture, dust, and corrosion, reducing environmental hazards and enabling safer, long-term operation. Use in outdoor or damp indoor facilities, control rooms, and exposed equipment areas. Voltage rating and system compatibility: With a 488 V rating designed for common 480 V industrial systems, the SPC050480N3P fits many existing installs, minimizing misapplication risk. Its single-phase configuration keeps wiring straightforward and cost-effective. Installers benefit from predictable performance in both new builds and upgrades. Indication and maintenance: An audible alarm provides immediate feedback when surges occur, helping maintenance staff verify protection without monitoring panels constantly. This feature reduces mean time to detect and respond to power events, supporting tighter MTTR metrics. Combine with regular inspection notes and Eaton's datasheet for maintenance planning. Compliance and lifecycle value: UL 1449 listing confirms adherence to safety standards, while a 10-year warranty reflects long-term reliability and total cost of ownership benefits. The SPC series design emphasizes compatibility with existing Eaton protection devices and SPC configurations, simplifying procurement and stocking. In practice, users see improved uptime, reduced spare parts needs, and steadier production lines.

FAQs
Install the SPC050480N3P by mounting it on the panel’s exterior side per Eaton’s instructions. Run the line and load conductors to the device terminals, observe proper grounding, and use the correct overcurrent protection. Ensure secure mounting to resist vibration in industrial settings, then verify wiring with insulation and continuity checks before energizing.
Best suited for industrial power protection in single-phase 480 V systems, the SPC050480N3P guards automation panels, motors, sensors, and control circuits from transient surges and voltage spikes. It supports SPC series deployments in manufacturing lines, processing equipment, and packaging stations where reliable uptime is critical. The 50 kA rating and 488 V clamp behavior help meet performance requirements for both new builds and retrofit projects.
UL 1449 listing confirms compliance with recognized safety standards for surge protection devices. The unit is housed in a NEMA 4X enclosure suitable for wet or dusty environments, and Eaton backs it with a 10-year warranty. These certifications and the long warranty translate to lower risk, easier procurement, and predictable lifecycle costs for mission-critical applications.
External side mounting simplifies retrofits and serviceability by keeping wiring accessible and reducing cabinet interior work. It also streamlines alignment with existing protection schemes and allows straightforward replacement without major disassembly. Together with the rugged NEMA 4X enclosure, this approach supports reliable operation in harsh environments and reduces downtime during maintenance or upgrades.
The audible alarm provides immediate notification of surge events, enabling quick verification of protection status without constantly monitoring the panel. This reduces MTTR, guides proactive maintenance planning, and helps maintenance teams document surge activity for reliability reporting. Paired with the UL 1449 protection and long warranty, it supports a proactive approach to asset protection.
