SPD - for data, signalling and telecommunications lines / I&C / Spare modules

Replacement module for BDG-024-V/1-4(F)Rx.

Pluggable module, coupling impedance (R – resistance)

• Lightning current arrester with coarse and fine surge protection for two 2-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 interfaces of I&C, MaR systems, electronic security and fire detection systems, etc. (mainly for RS-485 inter- faces) against impact of surge voltage.
• Coarse and fine surge protection (core – core) in differential mode and coarse surge protection in common mode (line – PE).
