<p>The invention deals with the procedure particularly for surge protection of telecommunication devices with the help of surge diverters, PTC-resistors and voltage limiting elements as well as a protective circuit for providing it. The aim of the invention, to develop a procedure and a protective circuit particularly for surge protection of telecommunication devices, which allows a transient current resistive and reversible protection of the line, is met in such a way that the reactive voltage of the surge protection (1) is higher than the maximum value of the supplied voltage and that the reactive voltage of tyristor diodes (4, 5) is set only slightly above the maximum values of the operating voltage line, which needs to be protected and that the PCT-resistors (2, 3) are used as a separating element and that they block the maximum amplitudes of the supplied voltage.</p> |
