Surge protection device and modular surge protection system

A surge protection device comprising at least one disconnecting device, at least one actuating device, an indicating device, and a shaft mounted for rotation between at least a first shaft position and a second shaft position,

• wherein the at least one actuating device is variable between a first actuating position and a second actuating position,
• wherein the shaft, the indicating device and the actuating device are formed in such a way and the actuating device, when in the first actuating position, is fastened to the at least one disconnecting device so as to be preloaded such that when the disconnecting device is triggered, the actuating device is released and triggers the indicating device by means of the shaft,
• wherein, when the disconnecting device is triggered, the actuating device becomes at least partly detached from the disconnection device.
