250 kA per phase surge rating provides aggressive clamping of transient energy, reducing voltage spikes that threaten drives and controllers. This translates to fewer trip events, lower maintenance costs, and extended equipment life in high-energy environments such as motor rows or switching gear, making it ideal for 230/400 V systems. The rugged NEMA 4 enclosure with an internal circuit breaker enhances ingress protection and safety during installation and maintenance, reducing field risk and downtime in harsh industrial spaces. The 230/400 V Wye (4W+G) configuration ensures compatible connection to common three‑phase power networks, supporting straightforward integration into existing control panels and switchgear without reengineering. UL 1449 listing reinforces compliance with recognized surge protection standards, delivering reliable performance that engineers can verify during audits. Seamless compatibility with Eaton’s Power Xpert SPD family enables centralized protection strategy, monitoring, and maintenance planning, driving a lower total cost of ownership for facilities and OEMs. The compact footprint and weight characteristics (9.5 in L, 17.05 in H, 15 in W, 52 lb) help optimize panel space planning and mounting in crowded switchgear rooms, supporting scalable deployment across multiple lines and projects.
