DM-006/n z

DM-012/n z

DM-024/n z

DM-048/n z

Combination of coarse and fine surge protection for telecommunication and signalling networks

n = 1 or 2 – number of cores 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.
