3-Electrode Gas Discharge Tube (GDT)

SC3E6 Series

Description

SC3E6-XXXMM

SC3E6-XXXM

Gas discharge Tubes (GDT) are classical components for

protecting the installations of the telecommunications. It is

essential that IT and telecommunications systems -with their

high-grade but sensitive electronic circuits - be protected by

arresters. They are thus fitted at the input of the power supply

system together with varistors and at the connection points to

telecommunication lines. They have become equally indispensable

for protecting base stations in mobile telephone systems as well as

extensive cable television (CATV) networks with their repeaters

and distribution systems.

These protective components are also indispensable in other

sectors, In AC power transmission systems, they are often used

with current-limiting varistors, In customer premises equipment

such as DSL modems, WLAN routers, TV sets and cable modems

In air-conditioning equipment, the integral black-box concept offers

graduated protection by combining arresters with varistors, PTC,

diodes and inductor.

Cautions and Warnings



Gas discharge tubes (GDT) must not be operated directly in power supply networks.

Gas discharge tubes (GDT) may become hot in case of longer periods of current stress (danger of burning).

Gas discharge tubes (GDT) may be used only within their specified values. In the event of overload, the head contacts may

fail or the component may be destroyed.



Damaged Gas discharge tubes (GDT) must not be re-used.
