Abstract
There is provided a surge protection device that includes (a) an input and an output, (b) a short-circuit-proof primary current path and a secondary current path between the input and the output, and (c) a fuse in a short-circuit-proof fuse box. The short-circuit-proof fuse box is arranged in the secondary current path, and (i) on one side of the secondary current path is contacted with the primary current path in a short-circuit-proof manner based on the primary current path, and (ii) on the other side of the secondary current path is contacted in a substantially short-circuit-proof manner based on the fuse. A help system for signalling and/or supply of devices for improving ignition behavior is arranged in the secondary current path, and the short-circuit-proof fuse box is also contacted to a short-circuit-proof discharge path so that a current can be guided by the help system current path.
