Abstract: An arrester and a method for producing an arrester are disclosed. In an embodiment the method includes providing at least three green layers, wherein each layer includes at least one green sheet, introducing at least one hole into a first layer and applying an electrically conductive material for forming inner electrodes to a second layer and a third layer. The method further includes laminating the layers to form a green stack, wherein the first layer is arranged between the second layer and the third layer, separating the green stack into individual components and compacting the individual components, wherein laminating the layers and compacting the individual components are effected in a single temperature process by co-firing.

Abstract: A computer-implementable method for simulating the electrical behavior of a surge arrester comprises providing a model of the surge arrester with a switchable current path between an anode and a cathode of the surge arrester, wherein the current path comprises a controllable voltage source. The current path is switched into the conducting or blocked state depending on a determined value of a voltage rise of an input voltage present between the anode and the cathode and a determined level of a response voltage. A level of the voltage of the controllable voltage source is set depending on a level of a current flowing in the current path.

Abstract: A contact device for an electrical switch, and an electrical switch are disclosed. In an embodiment the contact device includes a first connection element, a second connection element, a movable contact bridge, at least two magnets configured to quench arcs which arise during a switching of the electrical switch, wherein the magnets are configured to generate a magnetic field in a first region which comprises at least one first contact region and one second contact region, in which, when the electrical switch is in a closed switching position, the first connection element and the second connection element are in contact with the contact bridge and at least one deflection element configured to distort the magnetic field such that a first arc when formed between the first connection element and the contact bridge, and a second arc when formed between the second connection element and the contact bridge, are forced into different directions, pointing away from each other.

Abstract: A surge arrester includes a gas-tight discharge chamber that is formed by at least one insulating body and two electrodes. The electrodes extend into the discharge chamber and include an electrode spacing with respect to one another and a wall spacing with respect to the insulating body inner wall. The electrode spacing is equal to twice the wall spacing or is less than twice the wall spacing.
