An electronic circuit for a battery-electric vehicle for the switching-off of semiconductor switches in the event of critical currents, the electronic circuit includes at least two semiconductor switches that are connectable in parallel with one another between an energy supply source and a load. The electronic circuit includes a control unit configured to detect a current flowing through the at least two semiconductor switches, and, based on reaching a critical current, to switch off the at least two semiconductor switches. The electronic circuit includes a delay circuit connected in parallel with the at least two semiconductor switches and is configured, in the event of a not-exactly-simultaneous switching-off of the at least two semiconductor switches, to absorb a part of the critical current that switches over from at least one first-switching-off semiconductor switch to another one of the at least two semiconductor switches.
