3-Electrode Gas Discharge Tube (GDT)  
UN3E8 Series  
UN3E8-XXXHM  
UN3E8-XXXHMF  
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.

UN3E8-XXXH  
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.
