DM-024/1-RB

Describe first line
coupling impedance (resistance), screwless terminals
Product description
  • coarse and fine surge protection for 2-core signalling networks
  • installation close to protected equipment
  • for protection of communication interfaces, mainly the RS-485 lines, of I&C, electronic security and fire detection systems, etc. against impact of surge voltage
  • coarse and fine surge protection in differential mode (core – core) and common mode (core – PE)
