160 kA per phase surge rating delivers robust transient suppression, protecting downstream equipment and reducing nuisance trips, which translates to higher line availability for critical processes. The 240V high-leg delta (4W + G) on the B phase is specifically configured for delta-wye systems common in heavy industry, ensuring uniform protection across all phases and minimizing miswiring risks during panel upgrades or retrofits. The NEMA 4 enclosure with an internal circuit breaker provides rugged, weather-resistant protection and simplifies field installation and maintenance, enabling quicker isolations for service without additional external gear. Power Xpert SPD compatibility integrates this unit into Eaton's protection ecosystem, enabling centralized monitoring, diagnostics, and streamlined replacement planning for multi-site operations. Finally, compact dimensions (9.5 in L, 15 in W, 17.05 in H) and a 52 lb weight support straightforward space planning and panel mounting, reducing installation time and retrofit costs.
