The device delivers a robust 300 kA per phase surge capacity for 277/480 V Wye systems, enabling fast clamping of high-energy transients. This translates to minimized voltage excursions that threaten PLCs, drives, and motor controllers, effectively reducing unplanned downtime and maintenance costs. It is ideal for factory floors, process lines, and data centers where robust protection is essential. The Max series enclosure is NEMA 4 rated and includes an internal circuit breaker, delivering weather resistance and internal protection without requiring external devices. This design supports indoor and outdoor installations, simplifies wiring, and reduces panel space requirements. A standard surge counter provides real-time monitoring and historical data, improving asset protection and enabling easier compliance reporting. RoHS compliance and certifications like UL 1449 and UL 1283 validate safety and performance for critical panels, while the warranty coverage further lowers lifecycle costs. Single-module design with a compact footprint supports easy retrofits into existing protection schemes, helping installers meet tight project timelines and budget constraints.
