CNP series (GDT protection)

CNP protectors are based on GDT to provide high discharge current capability without destruction. These type of products allows for installation in ungrounded systems. In these cases, the CNP isolates the shield from the earth ground and is typically found in applications including wireless radio terminals and TV monitors (antenna, cable or satellite).

INSTALLATION, LOCATION OF THE SPD

The efficiency of coaxial protectors is highly dependent on proper installation, in particular their connection to the earthing network of the installation.
The following installations rules must be strictly observed to ensure the efficiency:

Equipotential bonding network: all the bonding conductors of the installation must be interconnected and connected to the installation earthing network.
Optimized connection of the protector to the bonding network: to reduce the residual voltages during lightning discharge currents, the connection of the protector to the bonding network must be as short as possible (less than 50 cm) and has a proper cross section (at least 4 mm²).

The «feedthrough mounting» versions perfectly meet all these requirements.
Warning: Carefully remove all paintings or insulating coatings to ensure good contact..

Location of the protectors: they should preferably be placed at the entrance of the installation (to limit the penetration of lightning currents) and also near sensitive equipment (to enhance protection).
