Combination of coarse and fine surge protection for telecommunication and signalling networks z = coupling impedance (R – resistance, L or L2 – inductivity) Designed to protect 2-wire telecommunication, data and other lines and the communication interface of M&C, ESS, EFS control systems, etc. against pulse overvoltage. Longitudinal overvoltage (core –earth) and lateral overvoltage (core- core) are prevented by a two-level combination of coarse and fine surge protection.
