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