High surge current handling delivers immediate protection for downstream equipment, reducing the risk of unplanned downtime and costly repairs; the result is longer asset life and lower maintenance costs in manufacturing lines and distribution panels. The 100 kAIC interrupt rating provides robust clamping during peak events, which translates to fewer nuisance outages and more consistent process control in industrial environments. The 127/220 V Wye (4W+G) configuration supports common commercial and industrial power systems, enabling direct installation into existing control panels without costly reconfigurations. The NEMA 1 enclosure with external side mounting simplifies installation, minimizes space requirements, and improves field serviceability in crowded electrical rooms. With a standard feature package and an integrated surge counter, you can quantify surge exposure over time for better maintenance planning and ROI calculations. The 15 year warranty further reduces lifecycle costs and reinforces long-term protection strategy for critical assets.
