Abstract

The invention relates to a mechatronic circuit-breaker device (1) adapted to break an electrical current flowing through electrical power transmission means (L), the device comprising: ¢ a main branch (10) comprising at least one electromechanical switch-disconnector (100) connected in series with at least one breaker cell (101) itself electrically in parallel with a snubber (102) and a first voltage surge limiter (103); ¢ an auxiliary branch (11) electrically in parallel with the main branch and comprising at least one power electronic switch (111), connected in series with at least one capacitor (1120), itself electrically in parallel with its discharge resistance (1125) and a second voltage surge limiter (1124), Characterized in that The first voltage surge limiter (103) has a sharper voltage-current characteristic and offering a much steeper slope at low currents than the second surge limiter (1124).
