An electric power supply disconnecting device comprising a pyro mechanical separation device 16; a Rogowski coil 10 for detecting an event on a current line 12 connected to the pyromechanical separation device and for generating a voltage pulse in case of a detected event; circuitry 14 for processing the voltage pulse and triggering the pyrotechnical separation device 16 depending on the processing. The circuitry may comprise a comparator means (fig.2, 20) for comparing a Rogowski coil output signal with a reference signal set to a value of a fault current representing an event on the current line; and a switching means, controlled by a comparator means output signal, connected between a ground contact of the pyromechanical separation device and a predefined voltage potential. The circuitry may comprise a digital circuit (fig.3, 28) or a delay circuit (fig.2, 24) adapted to delay the output signal of the comparator means by a time span. A method providing said disconnecting device in a current line used to disconnect the power supply from a load in a vehicle, particularly an electric vehicle.
