3-Electrode Gas Discharge Tube (GDT)
UN3E5 Series
UN3E5-XXXLM
UN3E5-XXXL
Description
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.
UN3E5-XXXLSMD
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.
