摘要： The invention relates to a pluggable surge arrester comprising one or several surge protection elements which are disposed within a structural unit with an optical fault indicator. The inventive surge arrester further comprises a thermal surge protector (5) that encompasses a mechanical actuator for triggering a remote indication contact in order to signal a fault. A linearly guided slide (1) is provided which is movable perpendicular to the plugging direction of the arrester and is equipped with an elastic tongue (2). The free end (3) of said tongue (2) can be blocked by a locking element (4). Furthermore, the thermal surge protector (5) is fitted with an actuating bolt (6) which acts upon the free end (3) of the tongue (2) when triggered in order to move the free end (3) out of the blocked position such that the slide (1) is released. The movable slide (1) has a free, web-shaped section (7) which penetrates a corresponding opening in the arrester housing. The invention also relates to a base part (16) for mechanically or electrically receiving at least one pluggable surge arrester, said base part (16) comprising a switching device (21) for the potential-free remote indication of fault states, especially a micro pushbutton (21).

摘要： The invention relates to an overvoltage protection device with a mechanical arresting device which is activated in the case of thermal overload, wherein said devices comprise connector elements which can be moved by means of a spring-loaded or pretensioned slider (4) from a closed position to a position in which current is interrupted or voltage is cut off, and wherein the closed position of the connector elements is maintained by a solder material or a thermally detachable adhesive. According to the invention, the connector elements consist of a pair of current-dividing metallic brackets (1, 1'), wherein the ends of said brackets (1, 1') which are directed toward the overvoltage protection element run parallel and include the corresponding contact lug (14) therebetween. The ends of the brackets (1, 1') which are turned away from the overvoltage protection element are connected to each other, enclosing a free space, and have a section (12) for external connector components or connector clamps. The slider (4) with pretensioned spring (2) is set in the free space, wherein the spring pretensioning is directed in the direction of the contact lug (14) of the overvoltage protection element. Furthermore, the slider (4) has a wedge shape and/or sections of the brackets have an inclined surface in order to generate a force component on the parallel ends of the brackets when the slider moves in such a way that said ends of the brackets can be moved away by the contact lug. The aforementioned solder or adhesive connection is formed in the area of the parallel ends of the brackets and the contact lug.

摘要： The invention relates to a process for dimensioning an cut-off switch of arresting element for a surge absorber arrester whose switching motion movement is performed by a control tab that is adjusted by a permanently active spring force in the direction opposite to the holding force established by a protective solder. As per the invention, the force of the initial stress affecting the control tab and/or its solder location that generates an unsoldering force and/or a switching force, in addition to a permanently active initial stress, by at least one additional initial prestress force not dependent upon it, as well as supporting a supplementary switching force with an identical direction of flow, whereby its distribution of force is set in such a way at rest that when in rest moderate force affects the soldering location and a resulting force that is as great as possible conducts the switching motion during the unsoldering action.

摘要： The invention relates to a device for deviating overvoltages, comprising one or several parallel mounted overvoltage limiting elements, such as varistors, diodes or the like, arranged in a structural unit and comprising at least one switching device for the electrical separation of said elements in the event of thermal overload of said overvoltage limiting element(s), in addition to means for displaying and/or indicating a given error state. According to the invention, a first switching device is provided, said device entering into thermal contact with the overvoltage limiting elements and actuating or triggering an optical display once a first temperature limit (T1) is reached, in order to indicate a limit of use or or service life limit for the overvoltage limiting element(s). A second switching device, which also enters into thermal contact with the overvoltage limiting elements, is also provided. Said device initiates electric separation and display of an error state in a manner known per se when a second temperature limit (T2) is reached. Temperature limit (T2) is greater than temperature limit (T1).
