Abstract: A base element for an at least two-part overvoltage protective arrangement, has a support rail receptacle for receiving a support rail carrying an electrical potential, a first receptacle for receiving a first electrical conductor, a second receptacle for receiving a second electrical conductor, and a protective element receptacle for receiving an overvoltage protective element. An electrical connecting element for transmitting an electrical signal from the first receptacle to the second receptacle is produced between the first second receptacles. An electrical support rail contact element makes electrical contact with the support rail when the support rail is received by the support rail receptacle. The first and second receptacles receive electrical connector parts or adapter connector parts for electrical connector parts. An overvoltage protective arrangement with such a base element.

Abstract: Aspects of the innovations herein relate to surge protection devices. Such surge protection devices may have an arrester. The arrester may produce an equalization between different potentials and arrest a surge current during use. A sensor may be provided on the arrester, said sensor generating an electric switch-off signal. A switching device may receive the switch-off signal and separate the arrester from an electric circuit, the switching device and arrester being arranged in a physically separate manner from each other.

Abstract: A functional unit measures the insulation resistance of an electrical system when the power supply of the electrical system is switched off. The electrical system includes an electrical reference potential, at least one electrical outer conductor, and an earth line. The functional unit is formed as a switch unit for connecting an electrical measurement device. The switch unit is configured to be connected to the electrical outer conductor, the electrical reference potential, and the earth line of the electrical system. The switch unit includes first, second, and third switches.

Abstract: The object of the invention is a power supply device (12) having a control and/or regulating unit (22), a reference potential connection (26), at least one voltage potential connection (28), and a ground connection (30) for grounding the power supply device (12).

Abstract: An overvoltage protection device for protection of an electrical or electronic device, with a housing, with input and output terminals for electrical conductors, with line paths which each connect one input terminal to one output terminal, with first arresters which are used for symmetrical protection between the active conductors and with second arresters which are used for asymmetrical protection between the individual conductors and the ground potential, the individual first arresters each being connected by their first terminal to a line path and by their second terminal to a common connecting point so that they are at a common reference potential and symmetrical protection between two conductors is implemented by two first arresters located in series to one another. The overvoltage protection device can also be used in signal circuits with several signal conductors and can guarantee reliable protection of a connected electrical or electronic device against overvoltages.
