A service switching device comprises a housing having a front face, a mounting face, and a narrow face disposed between the front face and the mounting face. A connecting terminal disposed in a terminal accommodation area close to the narrow face has a terminal screw, accessible from the front face and moveable in a movement direction, including an operating end and a clamping end disposed opposite the operating end; a terminal body including at least one terminal area, in which a connecting conductor can be pressed against a busbar by the terminal screw, wherein the terminal body is accessible via a first housing opening in a wall of the narrow face; and a terminal cover part.

An electrical switching device with a quick-action fastening apparatus is disclosed for snapping the switching device onto a top-hat mounting rail in a service distribution panel. The quick-action fastening apparatus comprising at least one movable tab, which is associated with the fastening face of the switching device housing by means of at least one connecting part, which is integrally formed in one piece with the switching device housing, and in the state in which it is snapped onto the top-hat mounting rail, engages behind a longitudinal edge of the top-hat mounting rail, the connecting part being spring-elastic and being made from a material which has different mechanical properties than the housing material.

The disclosure relates to an electrical installation switching device, having a switching mechanism with a latching point which can be unlatched manually by means of a switching toggle or by means of an electromagnetic or thermal release, having a tripping lever which can be operated by the electromagnetic and thermal release and acts on the latching point, having a latching lever which forms one element of the latching point, and having a movable contact lever, which can pivot, is acted on by the electrical release in the event of a short-circuit and is moved permanently to the disconnected position by the switching mechanism in the event of a short-circuit or overcurrent. The latching lever (which is mounted in the enclosure such that it can rotate) together with the tripping lever forms the latching point. The tripping lever is mounted such that it can rotate on the same rotation axis as the switching toggle. A projection which holds a first limb of a U-bracket is integrally formed on the switching toggle, diametrically opposite the switching handle, and its other, second limb is guided such that it can move in an elongated hole in the elongated latching lever and is connected in an articulated manner to a connecting lug, whose other end is connected to the contact lever, which is mounted such that it can rotate.

The invention relates to a quick-fixing device on electrical installation equipment, in particular, on a power breaker, residual current circuit breaker, or similar, for clipping the same to a standard profile rail in particular a top-hat rail, whereby the electrical installation equipment comprises a recess on the fixing side with a fixed lug arranged on a wall of the recess and a moving lug permanently pressed inwards against a spring force in the direction of a wall, said lug engaging in the assembled state behind the longitudinal edge of the free arm of the top-hat rail. The sprung lug is moulded to a bar, connected in one-piece to the installation equipment by at least one sprung connector web.

摘要:
A connection for two items of installation equipment lined up beside each other with their end or broad sides against each other, in particular line-protection circuit breakers, residual current circuit breakers and the like, whose housings are each formed from two shell-shaped housing parts. The connecting element has an approximately cylindrical base body with a first outer diameter onto which, on both sides, two radially springy spreading arms projecting axially in opposite directions are integrally molded. The outside diameter of the spreading arms is smaller than the outside diameter of the base body and free ends of the spreading arms have radially protruding lugs which, when assembled, latch in behind protrusions on the housings of the items of installation equipment located beside each other and to be connected by the connecting element.
