ST1+2+3 (BDM, BDG) - plugable

BDG-012-V/2-FR1

Order number: A06480

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

  • 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)
