100 kA per phase surge rating provides robust protection for critical loads, reducing equipment damage and unplanned downtime while enabling safer startup and operation in demanding environments. This translates to higher line reliability and lower maintenance costs across motors, drives, and control systems in manufacturing and processing facilities. The 240 Delta (3W+G) topology aligns with common industrial power architectures, minimizing rework and simplifying integration into existing panels and feeders. A rugged NEMA 4 enclosure with an internal terminal block supports outdoor or harsh indoor installations, improving wiring security and reducing service time during commissioning or maintenance. UL 1449 listing confirms compliance with safety standards, while Power Xpert SPD compatibility enables scalable protection across a plant or data center. The compact footprint, balanced weight, and mounting flexibility help engineers meet space constraints without compromising protection.
