Combination of coarse and fine surge protection for telecommunication and signalling networks Designed to protect 4-wire telecommunication, data and other lines and the communication interface of M&C, ESS, EFS control systems, etc., particularly RS 485, RS 422 and RS 232 interfaces, against pulse overvoltage. Longitudinal overvoltage (core – earth) is prevented by coarse surge protection. Lateral overvoltage (core – core) is prevented by a two-level combination of coarse and fine surge protection.
