Abstract

The device for connection to an electric circuitry consist of a pair of field transistors connected in series to a line of a circuitry the sources and drains of which are coupled together and the states of which can change by means of voltage applied on their gates (1) and a control unit connected to the gate of at least one of the field transistors (2). The control unit reacts to current overload on the line changing the state of at least of one of the field transistors.
