Claim Text:
1. A mechatronic circuit-breaker device adapted to break an electrical current flowing through electrical power transmission means, the device comprising: a main branch comprising at least one main module comprising at least one sub-branch comprising at least one mechanical switch-disconnector connected in series with at least one breaker cell constituted of at least one power semiconductor element with controlled duty ratio; an auxiliary branch electrically in parallel with the main branch and comprising: at least one first sub-branch, called the timing sub-branch, and comprising at least one first breaker cell comprising a plurality of power thyristors in cascade, at least one of the timing sub-branches further comprising at least one first switching-assistance module with at least one first capacitor, electrically in parallel with its discharge resistance and a voltage surge limiter; and a second sub-branch, called the arming sub-branch, electrically in parallel with the timing sub-branch and comprising at least one second breaker cell constituted of a plurality of power thyristors in cascade and at least one second switching-aid module with at least one second capacitor electrically in parallel with its discharge resistor; and at least one main voltage surge limiter electrically in parallel with the main branch.
