An electrical protection device, including a switching mechanism configured to switch between a set configuration and a tripped configuration, and a slide movable between a set position and a disengaged position. The electrical protection device further includes a resetting hook kinematically linked to a switching lever, and the slide supports a slide hook. When the slide is in the disengaged position, the resetting hook and the slide hook are ready to be engaged, and when the slide is in the set position, the slide hook and the resetting hook are spaced apart from each other and resetting of the electrical protection device results in engagement of the slide hook and the resetting hook and in a displacement of the slide.

A module for detecting an electrical fault includes a housing; a first conductor and a second conductor; a first measurement toroid, positioned around the first conductor and around the second conductor, for measuring a differential current flowing between the first and second conductors; a second measurement toroid, positioned around the first conductor, for detecting an electric arc signal flowing through this conductor; a relay; an electronic processing circuit configured to switch the relay according to the current measured by the measurement toroids. The measurement toroids are aligned with one another and the first toroid takes the shape of an elongated tube and allows the differential protection to operate with its own current.

The present invention is an electrical switchgear unit in a case and including at least one stationary contact and at least one movable contact supported by a contact support shaft, an opening and/or closing mechanism of the movable contact(s) fitted in a support, the mechanism including a manual operating handle of the contact(s) rotatable around a toggle pin of the case, and a high-speed closing shaft designed to keep the movable contact(s) in the open position, at the beginning of manual closing of the handle and over a certain travel, by storing energy and to release the movable contact(s) after travel of the handle so that the stored energy causes high-speed closing of the contacts. On one of its side faces, the device includes the support of the mechanism which includes an opening to accommodate at least a part of the high-speed closing shaft, which is inserted laterally at least partially into the support prior to fixing of the shaft inside the case, and the means for fixing said support inside the case is located on one side of the mechanism.
