pluggable module, coupling impedance (R – resistance), line separated from protective earth via GDT
- coarse and fine surge protection of shielded 2-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 the measuring circuits) against impact of surge voltage
- coarse and fine surge protection (core – core) and coarse protection (core – GND) in differential mode, coarse surge protection in common mode (line – PE)
