Function

This SPD handles high-energy surges generated by lightning (10/350 µs) as well as switching transients (8/20 µs). It provides protection in common and differential modes for three-phase + neutral networks. Thanks to QuickSafe technology and the integrated thermal disconnector, the SPD safely isolates itself during thermal overload or end-of-life events. Pluggable cartridges simplify maintenance while ensuring continuous protection performance.
