摘要： The invention relates to a surge protection device having a plurality of surge arresters and, in particular thermal, isolating apparatus which is respectively associated with them together with a fault and state display which is designed as a movable, spring force-prestressed displacement element (17) and has a display area and also an operating area for a telecommunications device, wherein tripping of the fault and state display is performed indirectly by means of a blocking element (1, 2, 3) of which the physical state can be changed. According to the invention, a blocking element is provided for each of the surge arresters, which blocking element is in each case arranged so as to block the movement path (4, 5, 6) of a mechanically prestressed wedge slide (7, 8, 9) with a wedge bevel (12). A rocker lever arrangement is also provided which has first lever arms (13, 14, 15) in accordance with the number of wedge slides and at least one second lever arm (16) for blocking, but also for releasing, the displacement element. Those ends of the first lever arms which are remote from the rotation axis (19) of the rocker lever arrangement each have an area (20) for sensing the respective wedge bevel of the respective wedge slide in such a way that, when the movement path of at least one of the wedge slides is cleared, its wedge bevel lifts the relevant first lever arm, as a result of which the second lever arm releases the displacement element.

摘要： The invention relates to a device combination for protecting electrical networks against overvoltages or overcurrents, comprising an essentially U-shaped base and at least one plug-in module, which can be plugged or pushed onto the base, wherein the base has connection terminals for connecting to the respective network and also has plug-in contacts, which are connected to the connection terminals and are complementary to mating plug-in contacts or contact tongues of the plug-in module, and the plug-in module has a housing which accommodates one or more lightning and/or overvoltage arresters, and the mating plug-in contacts or contact tongues pass through a floor side of the housing. According to the invention, means are provided for changing the position and the distance between the plug-in contacts and the mating plug-in contacts or contact tongues, wherein, starting from a working position, with a closed, surge-current-resistant electrical connection, it is possible to select an idle position, in which the plug-in contacts and mating plug-in contacts or contact tongues are located in an isolation/disengagement position.

摘要： The invention relates to a lightning and overvoltage protection device for data networks, telephony services, electroacoustic installations or bus systems having at least two grid-side input terminals and at least two output terminals, to which the load that is to be protected can be connected, furthermore having a gas-discharge surge arrester that connects the input terminals and an inductance located between the respective input and output terminal. According to the invention, the inductances are configured as current-compensated inductors having a core and a primary winding and a secondary winding, wherein the load current flows through the windings in different directions so that the respective magnetic fields cancel out. In the event of transient overvoltages, the arising surge current is bypassed by means of a switching device that then closes at one of the two windings, for example the secondary winding, in such a way that, owing to the winding through which current flows, for example the primary winding, the core reaches saturation and the coupling between the windings is released, with the result that no voltage is established across the load and the voltage applied to the winding through which current flows ignites the gas-discharge surge arrester.

摘要： The invention relates to an overvoltage protection device with at least one overvoltage protection unit, consisting of a socket part and a plug part which can be connected to the socket part and which receives means for protecting against an overvoltage, wherein insulated electric conductors can be introduced into the socket part, said electric conductors being contacted using vampire or cutting clamps, thereby penetrating the conductor insulation, and with contact surfaces which can be found on the socket part and which correspond to mating contact surfaces on the base of the plug part. According to the invention, the socket part is made of multiple parts consisting of a base part and a lever part. The base part is designed as a marble panel and has multiple parallel grooves for inserting and receiving the insulated electric conductors. On one face of the base part, hook-shaped protrusions are provided parallel to the grooves. The lever part has axle stubs, which engage into the hook-shaped protrusions, on one lever end. The lever part has at least one cutting clamp on the lever part lower face facing the marble panel and in the vicinity of the axle stubs, wherein the cutting clamp leads to a plug contact which can be found in the lever part and which can be accessed from the upper face of the lever part in order to receive the plug part.
