Pluggable module, coupling impedance (R – resistance), line separated from protective earth via GDT
- Lightning current arrester with coarse and fine surge protection for 2-core signalling lines
- installation at the boundary of LPZ 0 and LPZ 1 zones or higher, at the line entry into the building and also installation close to the protected device
- for protection of communication interfaces of I&C, MaR systems, electronic security and fire detection systems, etc. (mainly for RS-485 interfaces) against the impact of surge voltage
- coarse and fine surge protection (core–core) in differential mode and coarse surge protection in common mode (line–PE)
