A switchgear contact device includes at least one first contact element and at least one second contact element which can be slid inside each other in a positive-locking manner, such that they can be connected to each other in an electrically conductive manner in order to create an electrically conductive connection. The at least one first contact element includes a first cup-like contact sleeve and the at least one second contact element includes a contact pin that is surrounded by a hollow cylinder-like enclosure and is centrally arranged therein. A peripheral free area is provided between the contact pin and the enclosure which can be closed on the front side by an annular stop on which a force is exerted and which is arranged such that it is displaceable in the axial direction of the contact pin.

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.

A cradle intended to be incorporated in a high-voltage electrical switchgear cubicle, including a mobile trolley bearing a switch apparatus provided with mobile contacts, a mechanism for operating the mobile contacts via operating springs and at least one coil for actuating the operating springs, a motorized protection shutter intended to prevent access to conductive busbars of the switchgear cubicle, and motorized device for driving the mobile trolley intended to be able to connect the switch apparatus to the conductive busbars. A first automation controller is embedded on the mobile trolley to control the operating mechanism and the actuating coil, and a second automation controller is embedded in the cradle to control the protection shutter and the device for driving the mobile trolley.

Motor control centers have units or buckets with an extendable/retractable power connection (stab) assembly and one or more operating lever interlocks that include a unit latch to latch to a cabinet and a power connection position interlock that blocks the handle of the units or buckets based on position of the power connection assembly, optionally also including a shutter cam that slides a shutter right and left.

A system and method for connecting supply power to motor control components includes use of a motor control center subunit with moveable supply power contacts. After a motor control center subunit is secured into a motor control center compartment, the supply power contacts may be advanced to engage supply power buses. For disconnection, the supply power contacts may be retracted and isolated from the buses before physical removal of the subunit.
