The overvoltage protection circuit includes a gas discharge tube and a current management circuit connected in series to the gas discharge tube. The current management circuit includes a varistor and a resistor that are connected in parallel between a first node of the current management circuit and a second node of the current management circuit.

A test plug block (1) for plugging onto a series terminal block (2), comprising a plurality of test plugs (4) connected to one another and two fastening parts (5), which are arranged on both sides of the plurality of test plugs (4) and are connected to one another by means of a grip piece (6), the fastening parts (5) each having a housing (7) and an insertion portion (8), which can be inserted into a receiving portion (9), the receiving portion (9) being formed in the clamp housing (10) of a fastening clamp (11) of the series terminal block (2).

A disconnect terminal includes an enclosure, a first conductor rail, a second conductor rail, a switching device, and an actuation device. The switching device can be switched by the actuation device from a connecting position, in which the first conductor rail and the second conductor rail are electrically connected by the switching device into a disconnecting position in which the electrical connection of the first conductor rail and the second conductor rail is separated or disconnected, and back. A visible portion of the actuation device aligns with a surface of a portion of an upper side of the enclosure or with a part connected with the enclosure. In the disconnecting position, the visible portion of the actuation device protrudes from a surface of a portion of an upper side of the enclosure or of a part connected with the enclosure in a clearly visible manner. An assembly is provided of at least two aligned disconnect terminals.

A plug-in connection arrangement for arranging a relay includes a terminal block comprising a relay holder configured to hold a relay. The relay comprises a bottom wall, a side wall, and a contact plug which projects out of the bottom wall. The side wall is arranged perpendicular to the bottom wall and includes an offset section which contacts the bottom wall and projects out into the relay in a direction of a surface normal of the side wall. The relay holder includes a socket configured to hold the contact plug of the relay when the relay is inserted into the relay holder. The relay holder also includes an insulating wall which, when the relay is inserted into the relay holder, is aligned parallel to the side wall and projects beyond the bottom wall to form an angled insulation section for the contact plug along a surface of the insulating wall.

An assembly includes at least two disconnect terminals and at least one coupling device, wherein the at least two disconnect terminals each include at least one switching lever. Each switching lever is adjustable independently from the other switching lever from a first switch position into at least one second switch position and back, wherein the switching levers are connectable by the at least one coupling device. The at least one coupling device connects the switching levers if the at least one coupling device is switched into at least one first coupling position, and the at least one coupling device separates the switching levers from one another if the at least one coupling device is switched into at least one second coupling position. A disconnect terminal includes the at least one coupling device.

A circuit breaker housing for holding a switching device unit and a number of connection contacts for a connection line and/or a busbar. The housing has a first housing part and a second housing part. In the joined, assembled state, the housing parts form a front side and a rear side opposite said front side and at least one connection side and end faces located opposite one another. A holding chamber for a connection module having one of the connection contacts is provided on the front side and/or on at least one of the connection sides.

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.
