Abstract
A self-triggering, bidirectional control electronics component for an electronic switch (50), for the detection and rapid shutdown of currents at a selected threshold value for both current flow directions, includes a threshold switch having a plurality of selectable shutdown threshold values for both current flow directions, the threshold switch coupled to a bidirectional current sensor system (65), arranged in the electronic switch, based on sensing of sensors on an input side of the threshold switch; and a high-speed de-energizing circuit (53) on an output side of the threshold switch including a high non-load circuit voltage for rapid removal of current from a magnetic drive coil (45), the high-speed de-energizing circuit being configured to rapidly remove the current from the magnetic drive coil when the bidirectional current sensor system senses a current greater than or equal to the selected threshold value among the plurality of selectable shutdown threshold values.
