Abstract

Described herein is an electric circuit configuration (1, 2) for switching an electrical load (3) by means of at least one switching means (5) associated with the electrical load (3). The electric circuit configuration (1,2) includes at least one analysis circuit having at least one measurement resistor (17) connected in series with the switching means (5), at least one first analysis means (23) for determining a parameter corresponding to the short-circuit current, and at least one second analysis means (25) for determining a parameter corresponding to the electrical load current. The first analysis means (23) is coupled in parallel with the measurement resistor (17) and the analysis circuit includes a further measurement resistor (21), to which the second analysis means (25) is coupled in parallel. The resistance of the measurement resistor (17) is smaller than the resistance of the further measurement resistor (21), and the measurement resistor (17) and the further measurement resistor (21) are connected in series.
