Surge protection 48V on DIN Hakel 42313 DTE 2/48 /L

DTE is a comprehensive series of overvoltage protection for protection of data, communication, measuring and regulatory lines against surge effects. It is recommended for use on the interface of the LPZ 1-2-3 protective zones according to ČSN EN 62305 ED. 2. All types ensure effective protection of connected devices against both transverse and longitudinal overvoltage according to ČSN EN 61643-21+A1, A2. Nominal operating current of individual protected lines I _l \u003d 0.1 A.
1. The grade is solved using three-round lightningists, 2 degree using Transil. The number of protected pairs is optional 1-2. It is produced on the nominal operating voltage of 6 V-170 V. For this type is a maximum discharge current of 10 ka (8/20 µs). To protect telephone lines, it is recommended to use the type with a nominal voltage for _n \u003d 170 V (with the code name"T").
