Kumwell KZ01.DTN-L is a complex range of surge protection devices designed for protection of data, communication, measuring and control lines against surge effects. These surge protection devices are recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 0A(B) – 1 according to IEC 62305. All types provide effective protection of connected equipment against common mode and diff-erential mode surge effects according to IEC 61643-21. The nominal current of ind-ividual protected lines IN < 0.5A
These devices consist of gas discharge tubes, series impedance and transils. The number of protected pairs is optional (1-2). These devices are produced for nominal voltage of 6V-80V. Maximum discharge current is 20kA (8/20).
