Pluggable
module, coupling impedance (R – resistance), line separated from protective
earth via GDT.
- Lightning current arrester with coarse and fine surge protection
of 4-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).
