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

Lightning current arrester with coarse and fine surge protection of 2-core high-speed 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 telecommunication lines (version BDGHF-230) and interfaces of I&C, MaR systems, electronic security and fire detection systems, etc. (mainly for RS-485, PROFIBUS interfaces) against surge voltage.
Coarse and fine surge protection (core – core, GND) in differential mode and coarse surge protection in common mode (line – PE).
