Product Information:

Surge arrester for telephone lines – RJ45 sockets protects a single pair of ISDN lines in telecommunication equipment.

Features:

  • Provides “coarse” and “fine” protection
  • Protect AC and DC systems

Benefits: Simple installation. Universal plastic adapter for mounting on DIN rail and GND 2 holder

Standards: EN 61643-11 (Surge Protection Devices)

Application: Install in front of NT for protection on telecommunication equipment on ISDN lines.

More Information:

Where low voltage, data, and telecom lines enter and exit the building, they must also be included in the Lightning Protection System. These include:

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

Field-based electronic equipment also needs to be protected.

By their nature, low voltage, data, and telecom lines are not as robust as mains power cables and as such do not carry the same magnitude of lightning current. However, the size of that voltage/current is large in comparison to the system operating voltage and, as such, these lightning-induced transients can still cause irreparable and expensive damage.

Since transients can be induced from the large electromagnetic field created during a lightning strike, care needs to be taken over the routing of such cables.

When selecting a data, telephone, or low voltage protector, extra care must be taken to ensure that the clamping performance of the SPD does not impede the data/signal transmission voltage.
