摘要： The invention relates to a circuit assembly for protecting a unit to be operated from a supply network against overvoltage, comprising an input having a first and a second input connection, which are connected to the supply network, an output having a first and a second output connection, to which the unit to be protected can be connected, and a protection circuit, which is provided between the first and the second input connections in order to limit the voltage present at the first and the second input connections. According to the invention, the protection circuit has a power semiconductor, in particular an IGBT, wherein a series circuit consisting of a diac, i.e., a bidirectional electrode, and a Zener element is connected between the collector and the gate of the power semiconductor, wherein the sum of the Zener voltage and the diac voltage results in a clamping voltage for the power semiconductor, which lies above the voltage of the supply network and defines the protection level.

摘要： The invention relates to a surge protection device, comprising at least one surge arrester and one thermally trippable switching device connected in series with the surge arrester, wherein the above-mentioned means form a structural unit and the thermal tripping means is arranged in the region in which heating of the surge arrester is to be expected on overloading thereof. The thermal tripping means is in the form of a stop part through which there is no operating or surge current flowing and which effects or enables unlatching of the switching device in the case of thermal overload. Furthermore, the stop part is coupled thermally and mechanically to a surface side of the surge arrester and blocks the movement path of a mechanically prestressed unlatching slide. In accordance with the invention, a contact platelet is inserted in the unlatching slide, said contact platelet producing an electrical connection between elements of the switching device and, with unlatching, the contact platelet is subjected to a shifting movement resulting in an interruption to the series circuit and movement of the unlatching slide into the space previously assumed by the contact platelet, wherein at least the section of that region of the unlatching slide which separates the elements of the switching device is insulating.

摘要： A surge protection device comprises at least one surge protection unit, consisting of a substantially U-shaped socket part and a plug part which can be fixed in the socket part and which receives a surge protector. Insulated electric conductors on or in the socket part are contacted by vampire taps or displacing terminals. The surge protection device also comprises openings or perforations formed in the socket part for receiving conductors. The openings are selectively designed so that the electric conductors are inserted into or through the openings, and the openings are exposed in a socket part region which can be covered by the socket part such that cutting surfaces located on the base of the plug part penetrate the conductor insulation during the plug-in process and directly contact the respective conductor.

摘要： The invention relates to a single- or multi-pole switching device, in particular for DC applications, having at least one rotating switching element (2) which is connected to a drive, and also comprising switching contacts (4, 5), connection pieces (7) and connection poles or connection terminals (8) and a housing arrangement which accommodates the abovementioned parts. According to the invention, a movably guided rotary cylinder (2) is formed in the housing arrangement, said rotary cylinder being located in a body which is designed as a rotary cylinder holder (1). The rotary cylinder (2) has at least one contact pin (3) which passes radially or tangentially or eccentrically through the rotary cylinder and has, at its end, a contact piece (4) in each case. Mating contact pieces (5) are arranged in the rotary cylinder holder (1), said mating contact pieces being electrically connected to the connection pieces (7) or connection poles or connection terminals (8). A narrow, arc-influencing gap is present between the rotary cylinder (2) and the rotary cylinder holder (1), wherein, as a result of the movement of the rotary cylinder (2), the electrical connection between the contact pieces (4) and the mating contact pieces (5) can be broken by way of the contact pin (3) and the resulting disconnection arcs (11) enter the air gap subject to an extension and are rapidly extinguished there.

摘要： The invention relates to a surge protection device, comprising at least one surge arrester and one short-circuit switching device which is connected in parallel with the surge arrester, can be thermally tripped and is spring-pretensioned, wherein the abovementioned means form one physical unit. The thermal tripping means is arranged in the region where heating of the surge arrester is expected when it is overloaded, and operating or surge current does not flow through said thermal tripping means. The thermal tripping means is in the form of a stop part which releases an unlocking slide of the switching device in the event of thermal overload. The switching device has two opposite contact pieces, wherein at least one of the contacts is of moveable design and is under spring pretension in the closing direction of the switching device. The opening state of the switching device is maintained by the unlocking slide, which is released by the thermal tripping means to close the switching device.
