Lightning current arrester for the protection of coaxial lines and telecommunication equipment against the impact of direct or indirect lightning strikes.
Suitable for combined and power supply installations.
- N Connectors
- Use on systems up to 70 volts
- 50Ω wave impedance
Benefits: Simple installation. Universal plastic adapter for mounting on DIN rail and GND 2 holder
Standards: EN 61643-11 (Surge Protection Devices)
Application: Install at the boundary of LPZ0 and LPZ1 zones at the line entry into the building.
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, signalling 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 electro-magnetic field created during a lightning strike, care needs to be taken over the routeing of such cables.
When selecting a data, telephone or low voltage protector, extra care must be taken to ensure that clamping performance of the SPD does not impede the data/signal transmission voltage.
