Embodiment Construction

[0030] figure 1 A schematic diagram of an overvoltage protection device 1 is shown, which is designed as a switchgear module and has a device base 2 and a device upper part 3 that can be plugged onto the device base 2 . The bottom of the device has on its two front faces an input terminal 4 and an output terminal 5 which are preferably designed as screw terminals or tension spring terminals and are arranged offset one above the other in two rows. In order to be able to simply plug the device top 3 onto the device bottom 2, sockets are formed in the device bottom 2 and corresponding pins are provided in the device top 3, wherein the sockets are conductively connected to the input and output terminals 4, 5, The contact pins are electrically conductively connected to a protective element 6 arranged in the upper part 3 of the device.

[0031] Figure 2 to Figure 5 schematically shows figure 1 The circuit-technical structure of the two-part overvoltage protection device 1 shown ...

Abstract

The invention relates to and describes an overvoltage protection device, particularly for the protection of electric low-voltage installations, comprising a unit base (2) and at least one unit top (3) that can be placed on the unit base (2). The unit base (2) comprises input and output terminals (4, 5) for electric conductors and contact elements, particularly in the form of a socket, connected to the input and output terminals (4, 5). The unit top (3) comprises counter contact elements, particularly configured as pins, corresponding to the contact elements and at least one protective element (6) connected between two counter contact elements, particularly a varistor. The overvoltage protection device can thus be used also where unacceptable operating conditions have to be transmitted directly via the protected line system, for example in the area of train signal technology. At least one line path (7) runs between two input and output terminals (4, 5) associated with each other via the unit top (3) such that the line path (7) is disconnected when the unit top (3) is not connected, and such that in at least one line path (7) in the unit top (3) at least one disconnecting element (8) is disposed such that in case the disconnecting element (8) is actuated, due to an unacceptable operating condition of the protective element (6), the respective line path (7) is disconnected even when the unit top (3) is connected.

Description

technical field [0001] The invention relates to an overvoltage protection device, in particular for the protection of low-voltage electrical installations, which consists of a device bottom and at least one device upper part which can be inserted on the device bottom, wherein the device bottom has holes for electrical conductors Input and output terminals and contact elements connected to the input and output terminals, especially configured as sockets, and wherein the upper part of the device has mating contact elements corresponding to the contact elements, especially configured as pins, and at least one of the two mating contacts A protective element connected between components, especially a varistor. Background technique [0002] The lines of measurement technology, control technology and regulation technology form the nerve thread of industrial plants. Electronic measuring, control, regulating and switching circuits connected to these lines are very sensitive to trans...
