• Lightning current arrester for 2/3-core signalling lines, 12 V DC, max. 1 A

Pluggable module, coupling impedance (R – resistance), line separated from protective earth via GDT.


  • Coarse and fine surge protection of 2/3-core telecommunication, data and other lines
  • Installation at the boundary of LPZ 0 and LPZ 1 zones at the line entry into building
  • For protection of communication interfaces of I&C, electronic security and fire detection systems, etc. (mainly for RS-485 interfaces). against impact of surge voltage.
  • Coarse and fine surge protection (core – core, GND) in differential mode and coarse surge protection in common mode (line – PE).
