Beschreibung
Zusammenfassung:	An overvoltage protection device includes: input terminals; output terminals; at least two overvoltage protection elements for forming staggered protection levels; and at least one longitudinal element electrically connecting an input terminal and an output terminal to conduct an operating current. In order to form a first protection level, a first overvoltage protection device is connected to two input terminals on an input side upstream of the at least one longitudinal element, and, in order to form a second protection level, a second overvoltage protection element is connected to two output terminals on an output side and downstream of the at least one longitudinal element, the at least one longitudinal element influencing a response of the at least two overvoltage protection elements in case of an overvoltage. The at least one longitudinal element is provided with a thermal overload protection device for reducing a possible current flow.
