    Abstract: An overvoltage arrester system for protecting an electrical installation from an overvoltage or impermissible amount of energy, includes a first metal oxide arrester in a first current path and a second metal oxide arrester in a second current path connected in parallel with the first current path. In order to ensure that the overvoltage arrester system is suitable for arresting especially high amounts of energy, in particular from pulsed energy inputs, while at the same time being especially fail-safe, in a current range, a characteristic voltage/current curve of the first metal oxide arrester has a lower voltage than a characteristic voltage/current curve of the second metal oxide arrester at the same current, and the first current path has a switch. An arrangement having an electrical installation and the overvoltage arrester system is also provided.

    Abstract: The object of the invention is a multi-contact element for a varistor wherein the multi-contact element has a sandwich structure, wherein the sandwich structure has two or more contact elements in a lowermost layer, and wherein the sandwich structure has at least one common connection electrode in an uppermost layer, wherein a first intermediate layer made of an electrically insulating layer of material is provided at least in segments between the lowermost layer (US) and the uppermost layer, wherein fuses are located in the first intermediate layer that are configured such that they are capable of sustaining a specified surge current, the specified surge current per fuse being less than the specified surge current of the varistor, wherein the fuses are embodied as vias within the first intermediate layer, wherein the fuses in the first intermediate layer are in direct electrical contact with the common connection electrode, wherein each of the fuses is in direct or indirect electrical contact with a subset of the contact elements (KE1, KE2), wherein the fuses provide blow-out channels in the first intermediate layer so that in the event of a thermal overloading of a fuse of the first intermediate layer, the affected fuse can vaporize through the blow-out channel.

    Abstract: A metal oxide varistor integrally formed with a heat protection structure that will automatically go to open circuit in conditions of overheating due to sustained over-voltages. The metal oxide varistor integrally formed with a heat protection structure has a body, an insulation bracket, a number of terminals and a fuse. The insulation bracket is deposited on the body and has a number of slots. The fuse connects to the body and one of the terminals. The fuse is mounted one of the slots of the insulation bracket. The fuse reacts to the overheating timely and the melting fuse spreads quickly with the assistance of capillary action evolved by the slots of the insulation bracket to speed up the action to go to open circuit in against damage due to sustained over-voltages.
