Lightning current arrester

Combined with coarse and fine surge protection for telecommunication and signalling networks.

Designed to protect 2-wire telecommunication, data and other lines and the communication interface

of M&C, ESS, and EFS control systems etc. at the boundary of LPZ 0A–LPZ 1 zones and higher. It is

installed directly before the protected equipment. The lightning current arrester and coarse surge

protection prevent longitudinal overvoltage (core – earth). A three-level combination of lightning

current arrester and coarse and fine surge protection prevents lateral overvoltage (core – core).
