Problems solved by technology

[0008] However, such a device is not entirely satisfactory
Its effect on the opening speed of mechanical switches is especially insufficient when fault currents are present in the circuit
Furthermore, it is not particularly easy to implement such a device on an existing contactor-breaker and to obtain a significant cut-off distance without oversizing the contactor

Abstract

The invention relates to a contactor-circuit breaker device (2, 102, 202), comprising: a switch (4) including two pairs of contacts (10, 12) each comprising a stationary contact (14, 16) and a moving contact (18, 20), the stationary contacts (14, 16) being connected in series to an electrical circuit (22), the switch (4) being capable of switching between a closed configuration of the electrical circuit (22) and an open configuration of the electrical circuit (22); a support member (24) for the moving contacts; a current cutoff module (6) able to switch the current from the electrical circuit (22) to the cutoff module (6); and a movement apparatus (26) for moving the support member (24) comprising a armature (44) capable of translating the armature such that the support member switches between the closed configuration and the open configuration through a translational and / or rotational movement.

Description

technical field [0001] The invention relates to the field of contactor-circuit breaker devices. [0002] More specifically, the present invention relates to a contactor-circuit breaker arrangement comprising: [0003] - a mechanical switch comprising at least two pairs of contacts, each pair of contacts comprising static contacts and moving contacts capable of contacting each other, the static contacts being connected in series with the circuit, the mechanical switch being able to operate in the closed configuration of the circuit and in the closed configuration of the circuit Switching between an open configuration in which the fixed and moving contacts of each pair of contacts are in mechanical contact and an open configuration in which the fixed and moving contacts of at least one pair of contacts are separated from each other. [0004] - support members for moving contacts; and [0005] - a current breaking module comprising a semiconductor device, the breaking module be...
