A retrofitting device for medium voltage panels which comprises a plurality of first and second horizontal CB contacts aligned in a first and second horizontal plane, a plurality of first and second vertical SWG contacts aligned in a first and second vertical plane, a first bar assembly comprising first connection elements for connecting each of said first horizontal CB contacts with a corresponding first vertical SWG contact, a second bar assembly comprising second connection elements for connecting each of said second horizontal CB contacts with a corresponding second vertical SWG contact, said first connection elements comprising a first portion and a second portion linked to each other and free to change the angular position with respect to each other in a vertical plane when in an unlocked condition, said second connection elements comprising a third portion and a fourth portion linked to each other and free to change the angular position with respect to each other in a vertical plane when in an unlocked condition, first locking means being provided to lock the first with second portions and the third with the fourth portions in a desired position in which said first horizontal CB contacts and said second horizontal CB contacts are positioned on a substantially same vertical plane.

Retrofitting device for medium voltage switchgear

An electrical adapter is disclosed for connecting a connection contact of a circuit breaker with an associated contact piece of an electrical circuit along which the circuit breaker has to be inserted, including a hollow tubular element having a first end portion and a second end portion configured to be electrically connected to a connection contact and a contact piece, respectively, an inner cavity of the hollow tubular element having, at the first end portion, a first frusto-conical shape. A first connector having a hollow deformable body and configured to be accommodated inside the first end portion. A locking body configured to be securely placed along the inner cavity of the hollow tubular element. A second connector including a first connection portion configured to be accommodated inside the first end portion of the hollow tubular element.

Electrical adapter, and related switchgear panel

An electrically insulating shell is disclosed, which includes a first half shell and a second half shell devised to be mutually connected together and shaped so as to define, once connected together, a central part delimiting a substantially closed space, which will encase a corresponding first portion of an associated electrical conductor. A first hollow portion protrudes from a first side of the central part, the first hollow portion being in communication with an inner space of the closed central part and adapted to surround a corresponding second portion of the electrical conductor. A second hollow portion protrudes from the central part from a second side opposite to the first side, the second hollow portion being in communication with the inner space of the closed central part and adapted to surround a corresponding third portion of the electrical conductor.

Electrically insulating shell, an electrically insulating device comprising such insulating shell, and related switchgear panel

A shutter device is disclosed for an electric switchgear panel, including a base configured to be placed on a bearing surface inside the switchgear panel, the base being adapted to support, positioned thereon, a current switching device movable between a connected position wherein the switching device is electrically connected to an associated electrical circuit and a disconnected position wherein the switching device is electrically separated from the corresponding electrical circuit, a frame having at least a portion which rises up transversally from the base and delimits a through aperture, a movable shutter operatively associated with the base and the frame and an actuating mechanism adapted to move the shutter between a first position where the shutter closes at least partially the through aperture and a second position wherein the shutter is retracted and leaves the through aperture at least partially opened.
