An overvoltage protection system with an overvoltage protection element (1) and an ignition aid which triggers the overvoltage protection element (1), the overvoltage protection element (1) having two main electrodes (2, 3) and an air-breakdown spark gap (4) which acts between the main electrodes (2, 3). An overvoltage protection system having a relatively small and also largely constant operating voltage is implemented by there being an ignition circuit (5) with an ignition voltage output (6) as the ignition aid, the overvoltage protection element (1) having an ignition spark gap (7) which acts between the main electrodes (2, 3) with at least one ignition electrode (8) and the ignition electrode (8) being connected to the ignition voltage output (6) of the ignition circuit (5).
