Surge protective devices for VLV networks and low currents

Telecommunication – Data transmission

The surge protective devices for data transmission and Coaxstops are designed to protect against overvoltage from atmospherical origin (lightning and electrostatic) the equipments connected to the communication networks as well external as internal.

  • Protections on DIN rail
  • Multilines cabinets
  • UHF coaxial connections

Plug-in modules are designed to protect communication and data transmission lines against lightning induced surges and interference.

These protections are installed in series with the network signalling their end of life with the loss of the communication.

They consist of a multi-level protection that enables to get both fast operation and low residual overvoltages, this along with a high derivation capacity of transients achieved using gas arrestors. Plug-in modules exist for operating voltages of 6, 12, 24, 48 or 170 V.

Altough inserted in serie with the network, the AST4007CC product is a parallel protection for the applications with very high frequency (end of life in open circuit).

The multi-line housings AST 7400 CC, equipped with 2 pairs plug-in modules, are designed to protect communication and data transmission lines against lightning induced surges and interference.

These protections are installed in series with the network signalling their end of life with the loss of the communication.
