Specials - limiting current


Order number: A06597

coupling impedance (resistance)

  • special two-stage surge protection of 2-core signalling line with current limiting
  • installation close to protected equipment
  • for protection of communication interfaces, mainly the measuring loops, of I<(>&<)>C, electronic security and fire detection systems, etc. against surge voltage where are long parallel lines with power network
  • coarse and fine surge protection in differential mode (core – core) and coarse surge protection in common mode (core – PE)
