SC2E5 Series

SC2E5-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.
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.
