An electrical protection device comprising: - a casing; - a first conducting path, comprising a first movable contact, which is movable relative to the casing, between: • a conducting position, in which the first movable contact electrically connects a first input terminal to a first output terminal belonging to the first conducting path, and • an insulating position, in which the first input terminal and the first output terminal are electrically insulated from each other; - a slider, to which the first movable contact is attached, the slider being slidable relative to the casing along a slider axis, between a set position, where the first movable contact is in the conducting position, and a tripped position, where the first movable contact is in the isolating position; - a first contact spring, applying a first contact force to the first movable contact by bearing on the casing, the first movable contact tending to drive the slider towards the tripped position, when the slider is in the set position, under the action of the first contact force; - a switching control, which is configured to change between a closed configuration and an open configuration; and - a first trip device, configured to be energised by an electrical fault of a first type; characterised in that: - the electrical protection device further comprises a first hook, which is carried by the slider, being movable relative to the slider, between: • a locked position, to secure the configuration of the switching control to the position of the slider, so that the slider is in the tripped position when the switching control is in the open configuration, and so that the slider is in the set position when the switching control is in the closed configuration, the switching control then holding the slider in the set position, and • an unlocked position, in which the first hook allows the slider to be moved from the set position to the tripped position even if the switching control is in the closed configuration; and - the first trip device is configured to trigger a tilting of the first hook from the locked position to the unlocked position when the first trip device is energised by an electrical fault of the first type. - a casing;
