摘要：A circuit arrangement for limiting overvoltages on lines between which a device which is to be protected against overvoltages is arranged contains a threshold value circuit (7; 13) which is connected to the lines (1, 2; 8, 9). The output of the threshold value circuit is connected to the control electrode of a solid-state switch (5, 12) which is arranged in series with a resistor (4; 11) between the lines (1, 2; 8, 9). Together with further resistors (3, 10) which are connected to the lines, the resistor (4; 11) forms a voltage divider which limits the magnitude of the voltage on the lines to a value which is dependent on the dimensioning of the resistors. <IMAGE>
