COMBINED SURGE PROTECTION DEVICE WITH INTEGRATED SPARK GAP

摘要

The object of the invention is a combined surge protection device with an integrated spark gap and with a fuse connected in series thereto, wherein the spark gap has two main electrodes and one auxiliary ignition electrode, having
a housing with a first connector and a second connector, with the first connector being electrically connected to the fuse, and with the second connector being electrically connected to the first main electrode of the spark gap, and with the second main electrode of the spark gap being electrically connected to the fuse on the interior of the housing,with the combined surge protection device also having an auxiliary fuse element that is connected electrically on one side to the first connector, and with the auxiliary fuse element being connected on the other side via an ignition circuit, which is arranged on the interior of the housing, to the auxiliary ignition electrode,with the combined surge protection device having another connector in the region of the auxiliary fuse element that can be contacted at substantially the same potential to the first main electrode, so that, in the case of overloading, an electric arc forms between the auxiliary fuse element and the other connector, which leads to the triggering of the fuse.
