Abstract (en)

[origin: WO2010063914A1] The invention relates to a current measurement device comprising a primary conductor (20) in the form of a flat section folded into an overall U-shape, through which the current to be measured flows, and a sensitive element magnetically coupled in the air to the primary conductor (20), said sensitive element extending between the two branches of the U along an axis (XX') orthogonal to the plane containing the U. According to the invention, the measurement device further includes current-switching means in the form of a bistable electro mechanical relay that can occupy, through the action of a command, either a closed position in which the current to be measured can flow or an open position that prevents the current to be measured from flowing, and the generally U-shaped primary conductor (20) constitutes one portion of an electrically conducting element (10; 11; 14) of a bistable electromechanical relay forming a current switch.
