High-energy surge protection delivers up to 120 kA per phase, guarding motors, drives, and switchgear against damaging transients. The business impact is clear: fewer unplanned outages and reduced replacement costs, even during severe weather or grid disturbances. In practice, data centers and manufacturing lines benefit from immediate fault isolation and consistent power delivery, supporting uptime targets and productivity. The 127/220 V Wye (4W+G) configuration simplifies integration with common industrial power rails, enabling rapid deployment in MCCs, panel boards, and machine control cabinets. This compatibility reduces engineering time and minimizes field rewiring, translating to lower installation costs and faster project turnover. A NEMA 4 enclosure with an internal circuit breaker delivers rugged protection and easy maintenance, resisting dust, water, and corrosion while facilitating reset during inspections. UL 1449 listing supports NEC compliance and safety requirements, helping procurement verify protection standards and enabling Power Xpert SPD ecosystem scalability for larger electrical fleets. Finally, its compact footprint—9.5 in depth, 17.05 in height, 15 in width, and 52 lb weight—facilitates precise space planning in space-constrained panels without compromising protection quality.
