Product Description

Lightning Current Arresters

BDM-06

BDM-12

BDM-24

BDM-48

BDM-230

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. Longitudinal overvoltage (core – earth) and lateral

overvoltage (core – core) are prevented by a threelevel combination of lightning current arrester,

coarse and fine surge protection
