High interrupt rating delivers protection against extreme surges, reducing upstream fault propagation and potential equipment damage. The SPC120277N6P offers a 120 kAIC rating, enabling you to shield critical loads during severe transient events in commercial and industrial panels. 277 V single-phase design aligns with many commercial and light-industrial power layouts, enabling straightforward integration into existing electrical cabinets. This compatibility simplifies procurement and minimizes rewiring costs while delivering targeted protection where it's needed. Rugged NEMA 4X enclosure resists corrosion, moisture, and dust, extending service life in wet or dusty environments. This enclosure supports outdoor and indoor installations, reducing protective enclosures retrofit costs. Integrated filtering reduces high-frequency transients while the built-in alarm provides real-time status and fault alerts, enabling proactive maintenance, quicker fault isolation, and lower unplanned downtime. External side mounting simplifies field upgrades and retrofits, allowing rapid installation without major cabinet modifications. This makes spares handling easier and reduces commissioning time. Ten-year warranty and UL 1449 certification offer long-term reliability and regulatory confidence, contributing to lower total cost of ownership and easier supplier audits.
