The invention relates to a system for protecting an electrical source or an electrical load, having a module comprising an input and an output, and an electronic safety device for the load that can be connected to the source. The module also comprises a voltage monitoring unit, a current monitoring unit, and semiconductor switching units and controllers associated therewith. According to the invention, in order to selectively apply the protection to the source or the protection to the load, a unit for electrical mirroring on the circuit side is provided so that in the event of source protection, the current monitoring unit is applied at the input end and the voltage monitoring unit is applied at the output end, and in the event of load protection, the voltage monitoring unit is applied at the input end and the current monitoring unit is applied at the output end.

An electrical adapter includes a post portion, an electrical terminal, and a cover. The electrical terminal extends from the post portion. The cover is slideably engaged with the post portion to selectively shield the electrical terminal.

A sensor device for a terminal block arrangement, wherein the sensor device comprises at least one sensor for measuring a physical quantity of the terminal block arrangement or at least one terminal block of the terminal block arrangement.

Abstract A method for implementing wiring on a matrix of conductor connection devices such as terminal conductor connection devices for connection of the ends of a conductor to at least one series terminal block uses at least one luminous element to identify conductor connection devices which are illuminated in the matrix directly or indirectly in accordance with a wiring diagram. The conductor connection devices that are illuminated by the luminous element and that are to be interconnected are connected to conductors, the ends of which are inserted in the conductor connection devices to establish a respective conducting wiring connection.

A plug connector, having a housing that has at least one slot for accommodating an exchangeable function module. The housing is configured for accommodating a supply unit and/or a locking unit in order to fasten the function module to the housing in a form-fit and/or force-fit manner.

A device (1) for accommodating an electrical or electronic component (400), in particular a relay socket for accommodating a relay, comprises a base body (100) with a receptacle (110) for the component (400). The device (1) also comprises at least one pair (300) of connecting terminals connected to the two electronic connections, wherein the pair (300) of connecting terminals comprises a first connecting terminal (310) for a first connecting wire and a second connecting terminal (320) for a second connecting wire. The first connecting terminal (310) is spaced apart from the receptacle (110) by a first distance in a first direction and the second connecting terminal (320) is spaced apart from the receptacle (110) by a second distance in the first direction, wherein the first distance and the second distance are different.

A quickly-mountable housing of an electronic device includes the holding member and a main body. The main body includes a lateral panel having a first edge, a second edge, a first groove, a second groove, a hooking structure, and two blocks. The first groove extends along a traversal axis and the second groove extends along a longitudinal axis. The hooking structure extends toward the traversal axis from a lower side wall adjacent to the second edge. The two blocks on two sides of the longitudinal axis extend from side walls of the second groove toward the longitudinal axis. The holding member in the second groove is in a closed position where a holding part of the holding member is within the first groove.

A terminal block includes a housing including a connection surface to which an electromagnetic relay is connectable. The housing includes at least one attachment groove that opens to the connection surface and extends toward inside of the housing. The at least one attachment groove includes a first groove portion and a second groove portion are disposed adjacent to and communicating with each other. The first groove portion includes a first narrow width portion disposed near the connection surface, a wide width portion disposed farther from the connection surface than the first narrow width portion, and a step portion at a boundary of the first narrow width portion and the wide width portion, the step portion being capable of restricting a movement of the holding member in a removal direction. The second groove portion is configured to be capable of accommodating the claw portion without elastically deforming.
