<p>This pertains to a protection device to be associated with a current cutout device (20), provided with at least one pair (2) of contacts, in an electrical circuit (3). The protection device comprises a measurement device (1.1) for detecting a defect in the electrical circuit, at least one pair (6) of trip contacts being able to take a closed or open position and having to energize a coil in order to manoeuvre the pair (2) of contacts of the current cutout device (20), a control device (1.2) for controlling the closing of the pair (6) of trip contacts in the event of detection of a defect, the instigating of a timeout and the opening of the pair of trip contacts in the event of the disappearance of the defect on completion of the timeout and the prevention of opening until the intervention of an operator in the event of persistence of the defect on completion of the timeout.</p> |
