A device for sectioning an electrical circuit is provided. The device includes a housing having two main sectioning terminals and, in the housing, a first member for sectioning a first electrical connection between the two main sectioning terminals, an automatic control, under the action of an electrical signal, of the first sectioning member from the closed position to the open position thereof, and a manual control member for resetting the first sectioning member from the open position to the closed position thereof. The device also includes, in the housing, two secondary sectioning terminals and a second sectioning member movable between a position for opening and a position for closing a second electrical connection between the two secondary sectioning terminals, the second sectioning member being coupled to the first sectioning member, commutation of the first sectioning member bringing about commutation of the second sectioning member.
