A partition cover for a switchgear enclosure includes a main cover with a lip arranged along a first edge of the partition cover, a sliding cover with a second lip arranged along a second edge of the sliding cover, and a locking mechanism. The sliding cover is slidably supported on the main cover. The locking mechanism is fixed to the main cover and operably connected to the sliding cover, the locking mechanism is arranged to lock position of the sliding cover relative to the main cover to fix the partition cover within an interior of a switchgear enclosure. Switchgear enclosures and methods of emplacing and removing partition covers from within switchgear enclosures are also described.

Device for a busbar system, wherein a housing of the device comprises, on one housing side, electrical connection contacts which are configured in such a way that they are passable through feed-through openings of a contact protection baseplate module of the busbar system and are insertable into uniformly spaced contact openings located below the feed-through openings of busbar modules provided inside the baseplate module for producing a direct electrical and mechanical connection to the busbar modules.

An electrical distribution block includes a first base, a second base, and a spacer plate discrete from the first and second base. The spacer plate is positioned between first base and the second base and secures the first base to the second base. A conductor block is connected to at least one of the first base or the second base. The conductor block includes a primary tap and a secondary tap.

A flipper-type electronics cabinet includes a cabinet body, two first sliding rails, two second sliding rails, two third sliding rails, a carrying tray, a door plate, an accommodating tray, and a circuit controlling device. The circuit controlling device is disposed in the cabinet body and includes a controlling interface, a controller, a master switch circuit, a first switch circuit, and a second switch circuit. The controlling interface includes a master switch key, a first switch key, and a second switch key. The controller enters an operation or standby mode according to the master switch signal received. When the controller enters the standby mode, the master switch circuit is switched-off, and when the controller enters the operation mode, the master switch circuit is switched-on. When the controller enters the operation mode, the controller is used to respectively control the first and second switch circuits to be switched-on or switched-off.

A locking mechanism (20, 22) for an electrical assembly (10). The locking mechanism (20, 22) has a detent hook (20) that is hinged to the electrical assembly (10) by a flexible detent hook web (30), and a detent hook bracket (32) that is used for deflecting the detent hook (20). Limiting structures (34, 35, 36, 37, 38) restrict mobility of the buckle bracket (32) when the detent hook (20) is deflected. The locking mechanism (20, 22) may be applied in an electrical assembly, such as terminals, distribution terminals or other electrical connection devices, fuse holders, etc., as well as switching devices such as protectors, motor protection switches and the like.

A mounting and latching mechanism of an electrical device for fastening to a standard rail, to an immovable claw, and to a claw that is movable via a spring force, wherein the movable claw can be translationally moved relative to the immovable claw and wherein the immovable claw and the movable claw are formed as one piece having a connecting spring structure. A one-piece design is possible because of the translational mobility, which provides for cheap and simple production.

Power busbar system for connecting devices having at least one contact protection baseplate module for receiving elongated and electrically conductive power busbar modules each having a plurality of uniformly spaced contact openings of a contact opening array, wherein electrical connecting contacts of a device to be connected are configured to be inserted into the contact openings of the contact opening array of the electrically conductive power busbar modules for producing an electrical and mechanical connection.

A device for securing a communications or automation device to a top hat rail, wherein the device includes a base body, which can be connected to the communications or automation device on a front side, where at least one fixed first securing element that includes a groove or an undercut that can be engaged with an offset end of a first limb of a top hat rail is provided on a rear side of the base body, at least one second securing element provided on the rear side of the base element, which can be moved in the direction of the first securing element, is pretensioned in relation to the first securing element via a spring mechanism and includes a groove or an undercut that can be engaged with an offset end of a second limb of the top hat rail.

A securing structure is provided, including a frame, a movable member, a fixed member, a first abutting member, a screwing member. The frame includes a passage. The movable member is slidably disposed in the passage, and includes a threaded portion and a guiding slot. The fixed member is affixed on the frame and extends through the guiding slot. The first abutting member has a first inclined surface and is pivotally connected to the movable member. The screwing member is detachably joined to the threaded portion.

A carrier rail housing comprises: a carrier rail receiving opening into which the holding legs of a carrier rail are insertable; a locking mechanism to secure the holding legs in a desired mounting position and comprising locking slides to interlock with the carrier rail housing in a locking position; a plug-in contact element arranged inside the carrier rail housing to face the carrier rail receiving opening; and a bus connector into which plug-in contacts of the plug-in contact element are insertable, the bus connector being connectable to a plug-in contact element of at least one additional carrier rail housing, wherein each of the locking slides comprises a first end that comprises a holding section that extends in sections into the carrier rail receiving opening in the locking position, so that the bus connector is secured between the holding sections of the locking slides and the plug-in contact element.
