Eaton SPC080277N5P Surge Protection Device - UL 1449

277 V single-phase operation simplifies integration with standard facility power rails and control circuits. This reduces wiring complexity, shortens installation time, and minimizes panel modifications for retrofits. In industrial environments, clean voltage alignment improves surge protection performance and reduces nuisance tripping in critical control loops. An 80 kAIC interrupt rating means the SPC080277N5P can absorb high-energy surges without transferring damaging energy downstream. This translates to longer life for sensitive electronics, fewer unexpected outages, and lower replacement costs across motor drives, PLCs, and sensors. The rating is especially beneficial in high-demand applications such as packaging lines and robotics cells. The NEMA 4X enclosure provides rugged protection against dust, moisture, and washdown conditions. This durability supports reliable operation on busy plant floors, outdoor installations, and challenging environments where exposure is common. The enclosure also facilitates external side mounting and straightforward retrofits into existing panels. Alarms and Form C relay offer immediate status signaling for proactive maintenance. Operators can integrate with SCADA or building management systems to trigger alarms when surges are detected or protection is engaged. This capability reduces mean time to repair and improves overall equipment effectiveness. External side mounting enables easier installation in crowded panels and retrofits without interior rework. The compact footprint (5.5 in L, 3.19 in W, 6 in H) and modest 2.5 lb weight streamline upgrades in space-constrained panels. Coupled with UL 1449 certification and a 10-year warranty, this device delivers long-term reliability and predictable total cost of ownership.
