Abstract
A lightning arrester device for protecting an electrical circuit connected to a low-voltage network against transient overvoltages includes a plurality of gas-type spark gaps each connected directly in parallel with each other across two common nodes. Each of the plurality of gas-type spark gaps individually has a surge current rating below a desired surge current rating of the device.
