A retention mechanism for attaching equipment to a mounting rail comprises a slider including a first retention section and a pivoting lever mechanical coupled to the slider. The slider is movable in a translational manner along a sliding direction with respect to a remaining portion of the retention mechanism. The lever includes a second retention section aligned with the first retention section in the sliding direction. A reception area for receiving the mounting rail is defined between the first retention section and the second retention section.

A support rail fastener for detachably fastening a component to a support rail includes: a mounting plate, the mounting plate having at least one attachment element and a guide; a first spring element; and a slider, the slider being displaceable on the guide, the first spring element being brought into a preloaded position by moving the slider on the guide. On the guide and on the slide latching elements are respectively provided which, when the first spring element is preloaded the latching elements are brought into engagement with each other such that the slider engages in a latching position. The support rail fastener in an initial position in which the slider is in the latching position and in which the mounting plate is placed on the support rail by the attachment element is movable along the support rail.

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 support rail fastener for detachably fastening a component to a support rail includes: a mounting plate, the mounting plate having at least one attachment element and a guide; a first spring element; and a slider, the slider being displaceable on the guide, the first spring element being brought into a preloaded position by moving the slider on the guide. On the guide and on the slide latching elements are respectively provided which, when the first spring element is preloaded the latching elements are brought into engagement with each other such that the slider engages in a latching position. The support rail fastener in an initial position in which the slider is in the latching position and in which the mounting plate is placed on the support rail by the attachment element is movable along the support rail.

Device for securing an object on a rail, having an elongated base body which may be placed transversely on the rail and which at one end comprises an integrated actuating element which, when actuated by a user, moves opposing latching hooks which are integrated in the actuating element and are suitable for engaging behind the rail, in opposite directions.

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.

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 power module includes a housing, a support bracket, a sliding member and a resilient recovery member. The housing has a first surface and a second surface. The support bracket is fixed to the first surface. The support bracket has a hook to retain a first side of a support rail. The sliding member is slidably connected to the support bracket. The sliding member has a latch member to retain a second side of the support rail. The resilient recovery member has a first end connected to the support bracket and a second end connected to the sliding member. The resilient recovery member is to push the sliding member to cause the hook member and the latch member to sandwich the support rail. The sliding member has a first unlocking end for applying a force against the resilient recovery member. The first unlocking end projects beyond the second surface.

A clamping mechanism for a din rail is provided. No external force is continuously applied to a sliding component to maintain the removal state of the clamping mechanism. The clamping mechanism does not require additional tools for recovery of the sliding component. Therefore, the efficiency of providing the clamping mechanism for easy disassembly and assembly on the din rail may be achieved.

An electrical apparatus including a locking device for locking on an attachment rail, including a tab that is moveable along a first axis between a locking position and an unlocking position, a deformable blade which connects the tab to a central portion of the casing and which exerts a resilient return force on the tab, the tab including a locking member arranged in a side face of the tab projecting along a second axis perpendicular to the first axis, the electrical apparatus comprising, on an inner face of the cover, a housing, the locking member being movable between a retained position inside the housing and a released position outside the housing.
