A circuit arrangement for current limiting and an electrical system comprising such a circuit arrangement. An output terminal of a current limiting control circuit is connected to a control input of a semiconductor switch via a limiting resistor (RB). The current limiting control circuit is configured to change an output impedance of the current limiting control circuit at the output terminal. The semiconductor switch is configured to set a current (I) in a circuit between an electrical power source and a load. An inductor (L) is configured to be connected to the electrical power source and to a terminal of the load and an input of the current limiting control circuit is connected to the inductor (L). The current limiting control circuit is configured to detect an overcurrent-related voltage drop (VL) of the inductor (L) and reduce its output impedance to increase an output impedance of the semiconductor switch.
