Claim Text:
1. A contactor-circuit breaker device comprising: a mechanical switch including at least two pairs of contacts, each pair of contacts comprising a stationary contact and a moving contact configured to be in contact with each other, the stationary contacts being connected in series to an electrical circuit, the mechanical switch being configured to switch between a closed configuration of the electrical circuit, in which the stationary and moving contacts of each pair of contacts are in mechanical contact, and an open configuration of the electrical circuit, in which the stationary and moving contacts of at least one pair of contacts are separated from each other; a support member supporting the moving contacts; a current cutoff circuit comprising a semiconductor device, the cutoff circuit connected in parallel to one of the pairs of contacts when the mechanical switch is in the open configuration and configured to, in response to the mechanical switch being in the open configuration and an electric arc appearing in at least one of the pairs of contacts, switch the current from the electrical circuit to the cutoff circuit and interrupt the current circulating in the electrical circuit; and a movement apparatus that moves the support member comprising an armature, the movement apparatus translating the armature such that the support member switches between the closed configuration and the open configuration of the electrical circuit through a translational and/or rotational movement, wherein the mechanical switch has a maximally open configuration, and the device includes a stop part that stops the translational and/or rotational movement of the support member when the mechanical switch reaches the maximally open configuration, and wherein the stop part is configured to be put in contact with the moving contact of the pair in which a distance between the moving contact and the stationary contact is smallest when the mechanical switch is in the maximally open configuration, the cutoff circuit being connected to the stop part.
