Product Information:

Coarse and fine surge protection for 2 core signalling networks.

Features:

  • Screwless terminals
  • Coupling impedance (resistance)
  • Use on systems up to 24 volts

Benefits: Coarse and fine surge protection in differential mode (core-core) and common mode (core-PE).Standards: EN 61643-21 (Surge Protection Devices).Application: Install close to equipment for protection of communication interfaces.

More Information:

Where low voltage, data and telecom lines enter and exit the building, they must also be included in the Lightning Protection System.A lightning surge protection device prevents damage to electrical and electronic equipment from transient over-voltage events by blocking or redirecting surge current to the ground instead of passing through the equipment.These include:

  • Electromagnetic shielding
  • Telephone lines
  • Data communication lines
  • Instrumentation, control, signalling lines
  • Coaxial lines for CCTV, TV, & antenna cables

Field based electronic equipment also need to be protected.
