摘要： The invention relates to a surge protector having a thermal separating device and an error display, and at least two first protection elements, particularly disk-shaped varistors (7), and at least one second protection element, particularly a gas arrester (9), wherein the first and the at least one second protection elements are switched in a Y arrangement, further comprising a device housing for accommodating the protection elements, and a means (11) for the mechanical biasing of the thermal separating device, wherein the thermal separating device has a low-melting solder, and the first protection elements (7) are disposed in the device housing such that a connection arm of a protection element (7) is positioned opposite the connection arm of the further protection element (7) at a distance, and the thermal separating device is predominantly positioned in the distance space (13) formed in such a manner. According to the invention, a connection arm of the second protection element (9) directly bypasses said connection arms (12) of the first protection elements (7) in the distance space in a solder-contacted manner, wherein a finger (16) of a mechanically biased separating block (5) acts upon the bypass connection arm (15) such that in the event of an overload the bypass connection arm (15) is spatially placed at a distance to the connection arms (12) of the first protection elements (7).

摘要： The invention relates to a surge arrester having at least one arresting element, for example a varistor and a disconnection apparatus, in order to disconnect one pole or all poles of the arresting element or elements from the power supply system, with the disconnection apparatus comprising a solder point (11) which is included in the electrical connecting path within the arrester, with a moving conductor section (12) or a moving conductive link (22) being connected via the solder point (11) to the arresting element on the one hand, and with the conductor section (12) or the link (22) being connected on the other hand to an electrical external connection of the arrester, and furthermore having a spring (15) which produces a prestressing force, with the force vector relating to them acting directly or indirectly on the conductor section (12) or the link (22) in the disconnection apparatus. According to the invention, a blocking element (17) which can be tripped thermally blocks the moving conductor section (12) or the moving conductive link (22) with regard to the prestressing force vector, so that the solder point (11) of the disconnection apparatus is not subject to any permanent load on the force side.

摘要： The invention relates to a plug-in combination of appliances for protecting against overvoltages, said combination of appliances comprising: a socket-type lower part and at least one plug-in module, which can both receive overvoltage protection elements; contact elements and contact counter elements that are respectively arranged in the lower part and in the plug-in module; and complementary guide rails or guide grooves for inserting or pushing-on and fixing the respective plug-in module. According to the invention, functionally separated, mechanical catch or snap-in elements act between the respective plug-in module and the socket-type lower part independently of the forces which hold together the contact elements and the contact counter elements in a positively fixed and/or non-positively fixed manner when the plug-in module is in use. The catch or snap-in function can be cancelled without any mechanical auxiliary means when the respective plug-in module is to be replaced.

摘要： The invention relates to an overvoltage protection device (7), which comprises at least one overvoltage protection unit having at least one contact lug (14) and which comprises a mechanical disconnection apparatus that is activated in the event of a thermal overload, wherein the mechanical disconnection apparatus comprises a connection element. The connection element can be moved from a closed position to a current-interrupting or voltage-disconnecting position by means of a slide (4) preloaded by spring force, wherein the connection element consists of a pair of current-dividing metal bows (1, 1'), the ends of which directed toward the contact lug of the overvoltage protection unit extend in parallel and which accommodate the respective contact lug of the overvoltage protection unit in the centre of the bows, wherein the closed position is secured between the connection element and the contact lug in the region of the ends of the bows extending in parallel by means of a solder (3). The ends of the bows facing away from the contact lug of the overvoltage protection unit are connected to one another in such a way that a free space is enclosed and have a segment for outer connection parts in the further course, wherein the slide having a preloading spring is inserted in the free space in such way that the spring preload is oriented in the direction of the contact lug of the overvoltage protection unit. The slide has a wedge shape and/or segments of the bows form a slanted surface in order to produce a force component acting on the ends of the bows extending in parallel when the slide moves, such that the ends of the bows extending in parallel move away from the contact lug laterally. According to the invention, the ends of at least one of the bows pointing toward the contact lug form a stop for a visual indicator that can be pivoted about an axis, wherein the pivoting motion is enabled when the ends of the bows extending in parallel are removed from the contact lug laterally by means of the slide.

摘要： The invention relates to an overvoltage protection device with a thermal disconnection apparatus and an error display (11) as well as a plurality of varistors (3), in particular disc-shaped varistors, wherein each discharge path is assigned at least one varistor and the thermal disconnection points (4) are in series with the respective varistor. Chambers (2) for accommodating the varistors are provided in the device housing (1). A pivotably mounted lever (10) with a display area (11) is also provided, wherein the display area is in the region of a housing window. Plug connections (6) extend through the bottom of the housing in order to establish an electrical connection to a base part. The thermal disconnection points each comprise a spring-prestressed (14) clip (9) which is electrically and mechanically connected to the respective varistor using a solder with a low melting point. The spring-prestressed clips are formed by a stamped and bent part which has finger-like extensions (9) starting from a common connecting limb. At least one plug connection is provided on the connecting limb. The finger-like extensions have, in the region of the free end thereof, a slotted recess (8) into which a connection wire or a connection leg of a varistor is respectively directly soldered. Furthermore, a heat trap is situated in the region downstream of the soldering point in the direction of the connecting limb, wherein a separate spring force is applied to each finger-like extension.
