<p>A safety circuit system for overvoltage protection of multiwire lipes (an, bn), In particular, of lines for telecommunication and the like. The protective system comprises a device (P1) for dispersing the overvoltage energy, connected between the various line wires (an, bn) and, respectively, between each line wire (an, bn) and earth wire (T) by means of a composite bridge of diodes (Dk, Dr, Dt, D min t) or overvoltage-activated solid-state switch means in which the energy dispersing device (P1) lies on a common diagonal of the bridge.</p> |
