Overvoltage protection device with thermal overload protection device

The main body of the invention is an overvoltage protection device (10; 10 ') for forming a graded protection stage, comprising at least two overvoltage protection elements (20; 21; 22) and at least one longitudinal element (30; 40), which electrically connects the input connection (13) and the output connection (14) in order to transmit an operating current, and is designed to influence at least one of the at least two overvoltage protection elements (20; 21; 22) of a vehicle. The at least one longitudinal element (30; 40) has a thermal overload protection device (50; 50 '), which is designed to reduce the temperature of the longitudinal element (30; 40), so that the longitudinal element (30; and 40) switching to a safe state. This is achieved, for example, by bridging the longitudinal elements (30; 40) and/or interrupting the longitudinal element (30; 40) of the motor (10). 本发明的主体是一种过压保护设备(10；10′)，该过压保护设备具有用于形成分级的保护级的至少两个过压保护元件(20；21；22)和至少一个纵向元件(30；40)，该纵向元件为了传输工作电流而电气地连接输入端子(13)和输出端子(14)，并且构造用于在过压情况下影响至少两
