Abstract
An electrical cut-off device (1) with high electrodynamic resistance in which the fixed contacts (4) and the moving contact (5) are arranged according to an architecture forming a current loop so that the Laplace electromagnetic forces, called compensation forces (Fc), generated by the circulation of the current (I) in the current loop, are oriented in a direction flowing from the inside toward the outside of the current loop, and in which the actuator mechanism (6) is arranged for moving the moving contact (5) inside of the current loop, from its switched-off position to its switched-on position in a direction (Fd) that is identical to the direction of the compensation forces (Fc).
