Reviews

Combined lightning and surge protection device type 1+2, for protecting low-voltage consumer systems against lightning currents and surges. Tested SPD type 1 and type 2 according to DIN EN 61643-11. The combined arresters can be used as surge protection devices according to 0100 part 443 and part 534. The devices consist of leakage-current-free spark gaps and are suitable for the pre-meter area. The function display is via an optical display and can be snapped onto the 40mm busbar system without tools.
