the present invention relates to a safety device 1 notably developed to promote more security and better efficiency in its use, i.e., to operate in the locking and actuation of electrical connectors positioned in extractable drawers 4 for MCC cabinets 16, thereby setting a safety device capable of connecting or disconnecting the internal connectors, both principal and test connector, provided in the extractable drawer 4 for MCC cabinet 16, said procedure is executed mechanically through an assembly of elements that interconnect two thin laminar plates 5 and 5A, these in turn, interconnected to each other, positioned inferiorly and of conformations corresponding to promote a perfect fit, being that the actuation is performed externally with the door closed, from the actuation of the actuation key 2 which actuates a pendulous element that moves a gear assembly 6 suitably arranged in the interior of said extractable drawer 4 for MCC cabinet 16, the gears 6B, 6C, connected to two lower thin laminar plates 5 and 5A, which move and actuate the test connector and subsequently the main connectors towards the corresponding busbars 12, being the laminar plates 5 and 5A interconnected to each other and of corresponding conformations, and said test device is actuated in the first movement of the actuation key 2 of the extractable drawer 4, connecting the test device in the extractable drawer 4 and, by means of sequential movement of the actuation key 2 of the system, the main connectors are actuated. |
