The invention relates to a protective device (47) for preventing electrical conductors from coming into contact in a power distributor unit (1), said power distributor unit (1) comprising a withdrawable compartment (2) and an electrical withdrawable unit (6; 7) that is mobile in the withdrawable compartment (2). Said protective device comprises at least one protective plate (22) that can move in the withdrawable compartment (2), from a closed position into an open position, and an actuating means (46) mounted on the electrical withdrawable unit (6; 7) and used to move the protective plate (22). In order to render the protective device even more reliable, the actuating means (46) engages above the protective plate or in same, in the closed position of the protective plate, when the electrical withdrawable unit (6; 7) is inserted into the withdrawable compartment (2) under the action of a control means (45); the protective plate (22) is arranged in the path of movement of the actuating means, both in the direction of the open position thereof and in the direction of the closed position thereof; and the actuating means (46) releases the protective plate (22) only once the protective plate has reached its closed position, when the electrical withdrawable unit (6; 7) has been removed under the action of the control means (45). The protective plate (22) can be moved in the withdrawable compartment (2), in a plane extending parallel to the direction (48) of movement of the electrical withdrawable unit (6; 7). |
