摘要： A surge arrester for the power supply of low-voltage systems, having a housing, two electrodes which are situated axially opposite one another, an arc combustion chamber formed in the interior of the housing, and a trigger aid. A spark gap is formed between the two electrodes so that an arc is produced when the spark gap between the two electrodes is triggered, the axial distance between end faces of the two electrodes being so large that the arc voltage is greater than the expected line voltage. Conversion of energy within the surge arrester is reduced by the arc combustion chamber having an inner region and at least one expansion region into which the arc can propagate after triggering. The inner region is arranged between the two electrodes and is delimited axially by the end faces of the electrodes and is delimited longitudinally by the at least one expansion region.

摘要： A cut-off element for electrical isolation of an electrical component or for opening of a circuit in overload has two terminal contacts, an insulating housing and a fuse element which is located within the insulating housing. In the normal state of the cut-off element, the two terminal contacts (2,3) are connected to one another in an electrically conductive manner via the fuse element. In the cut-off element, reliable isolation of an electrical component, in particular an overvoltage arrangement, is possible by the insulating housing being formed of two parts which are connected to one another and the first part of the housing, in case of overload, being isolated from the second part of the housing so that the connection of the two terminal contacts is broken via the fuse element.

摘要： An overvoltage protection element with a housing, an overvoltage-limiting component arranged in the housing, and with two connection elements for electrically connecting the overvoltage protection element to the current or signal path to be protected, wherein, normally, the connection elements are each in electrically conductive contact with a pole of the overvoltage-limiting component. Reliable and effective electrical connection in the normal state and reliable isolation of a defective overvoltage-limiting component are ensured by the fact that a thermally expandable material is arranged within the housing in a way that, in the event of thermal overloading of the overvoltage-limiting component, the position of the overvoltage-limiting component is changed by expansion of the thermally expandable material relative to the position of the connection elements in a way that causes at least one pole of the overvoltage-limiting component to be out of electrically conductive contact with the corresponding connection element.

摘要： A fuse has a first contact and a second contact, with the second contact being used to electrically contact the device to be protected. The fuse has a fuse element that connects the first contact to the second contact. The fuse also has an additional contact being arranged so as to be insulated from the first contact and insulated from the second contact and, in an untripped state, is contactless with respect to the fuse element, with the first contact being directly connected to the first potential during operation and with the device to be protected being directly connected to the second potential during operation, with the additional contact also being directly connected to the second potential during operation. A fourth contact makes external triggering available, with triggering resulting in an electric arc that causes the fuse element to fuse.

摘要： The object of the invention is an ignition circuit for a series connection of at least two spark gaps for limiting overvoltages with medium and high power, particularly overvoltages corresponding to pulse shapes 8/20 μs and 10/350 μs with amplitudes of about 10 kA to about 200 kA (class I arrester). The spark gaps are each equipped with at least one auxiliary electrode. The ignition circuit has a first varistor and a second varistor, with the ignition circuit being particularly suited to limiting overvoltages with medium power, particularly overvoltages corresponding to pulse shape 8/20 μs with amplitudes of about 10 to about 100 kA (class II arrester). The ignition circuit is designed to be connected to the auxiliary electrodes, with the ignition circuit Z having two ignition subcircuits. The first ignition subcircuit TZ1 has the first varistor VAR1 and is designed to ignite the first spark gap. The second ignition subcircuit has the second varistor and is designed to ignite the second spark gap. Further objects of the invention are an overvoltage protection device with this kind of ignition circuit, as well as the use of a multi-contact varistor for triggering a spark gap.
