Contactor-circuit breaker device

A contactor-circuit breaker device (2, 102, 202), comprising:

• a mechanical switch (4) including at least two pairs of contacts (10, 12), each pair of contacts (10, 12) comprising a stationary contact (14, 16) and a moving contact (18, 20) capable of being put in contact with each other, the stationary contacts (14, 16) being connected in series to an electrical circuit (22), the mechanical switch (4) being capable of switching between a closed configuration of the electrical circuit (22), in which the stationary (14, 16) and moving (18, 20) contacts of each pair of contacts (10, 12) are in mechanical contact, and an open configuration of the electrical circuit (22), in which the stationary (14, 16) and moving (18, 20) contacts of at least one pair of contacts (10, 12) are separated from each other;
• a support member (24) for the moving contacts (18, 20);
• and
• a current cutoff module (6) comprising a semiconductor device (8), the cutoff module (6) being connected in parallel to one of the pairs of contacts (10, 12) when the switch (4) is in the open configuration and being able, when the switch (4) is in the open configuration and an electric arc appears in at least one of the pairs of contacts (10, 12), to switch the current from the electrical circuit (22) to the cutoff module (6) and interrupt the current circulating in the electrical circuit (22),
• characterized in that it further includes a movement apparatus (26) for moving the support member (24) comprising an armature (44), the movement apparatus (26) being capable of translating the armature (44) such that the support member (24) switches between the closed configuration and the open configuration of the electrical circuit (22) through a translational and/or rotational movement.
