Overvoltage protection device

An overvoltage protection device, comprising:

• a housing,
• first and second terminals for electrical connection of the overvoltage protection device to a current path which is to be protected,
• at least one arrester which is located within the housing and having first and second connecting regions, the first terminal being connected in an electrically conductive manner to the first connecting region of the arrester and the second terminal being connected to the second connecting region of the arrester via at least one component, and
• a fusible element of metallic material within the housing, the fusible element having first and second contact regions and a connecting region which connects the contact regions to one another,
• wherein the first contact region of the fusible element is connected in an electrically conductive manner to the second connecting region of the arrester and the second contact region of the fusible element, in the normal state of the overvoltage protection device, is connected in an electrically conductive manner to the component,
• wherein the connecting region is formed as a fusible link by material reduction such that short pulsed currents which result from overvoltages which are to be discharged from the overvoltage protection device are able to be transmitted via the connecting region, while in case of a fault line-frequency short circuit currents flowing via the overvoltage protection device, the connecting region is constructed so as to overload and be destroyed, and
• further comprising a mechanical disconnector which is actuatable by a thermal overload in a manner that breaks the electrical connection between the second terminal and the component, and wherein the mechanical disconnector has a solder site and a spring element, the component remains in a position contacting the second terminal against the spring force of the spring element as long as the solder site does not melt.
