200 kAIC surge rating with a 277 V single‑phase input delivers robust protection for critical loads. This means far fewer surge‑induced failures in controllers, drives, and industrial sensors, translating into less unplanned downtime and longer equipment life. The SPC200277N4P is designed for external side mounting in standard control panels and compact enclosures, supporting quick retrofits without major cabinet redesign. With a NEMA 4X enclosure, the device withstands dust, water spray, and washdown environments typical of manufacturing floors and outdoor installations, ensuring dependable performance across shifts. The rugged construction complements the 200 kAIC interrupt rating, guarding against high‑energy transients that can ripple through a system, reducing wear on downstream components. Form C relay capability adds signaling and alarm potential, enabling straightforward integration with plant SCADA or maintenance dashboards. This feature supports preventive maintenance programs by providing reliable trip feedback and status monitoring. The 10‑year warranty and UL 1449 listing demonstrate long‑term reliability and compliance with electrical safety standards, helping reduce maintenance costs and streamline procurement. Lastly, the device’s compact dimensions—5.5 in deep, 6 in high, 3.19 in wide, and 2.5 lb—paired with external side mounting, simplifies retrofits and installations in space‑constrained panels, delivering dependable protection with minimal disruption.
