Combined surge protection, tested in category D, C, B (EN 61643), suitable for twisted pair cables for signal transmission. For protecting resistance-sensitive systems with frequencies between 120kHz and 160kHz. Suitable for direct current applications up to a maximum of 4 A. Available for nominal voltages of 6, 15, 30, 50 and 110 volts. For use at limits from LPZ 0 for protection against flashover (typically at the point of cable entry) up to LPZ 3 to protect sensitive electronic equipment.
