Protective circuit with a threshold circuit for discharging overvoltage surges to ground and with a low- value resistor positioned in a line wire at the subscriber's end meets a higher level of lightning protection by connecting a voltage-limiting component (V1, V2) in parallel with the low-value resistor (R1, R2). Such may a varistor connected in parallel with each of the series low-value feed or sensing resistors. The invention meets symmetry requirements, places low voltage requirements on low-value resistors and preceding parallel components, makes use of inexpensive voltage- limiting components and thereby results in cost saving.
