Abstract:
A method for operating an electronic circuit breaker having a semiconductor switch that is connected between a voltage input and a load output and that is driven as a function of the output voltage sensed at the load output during the switching on and/or cutting in of a capacitive load, wherein the output voltage is compared with a stored voltage threshold value, wherein when the voltage threshold value is reached or negatively exceeded, a current limit, to which a load current carried by the semiconductor switch is limited, is increased from a nominal value to a first step value increased therefrom, wherein the current limit is reduced stepwise from the first step value to the original nominal value, and wherein the semiconductor switch is opened if the output voltage does not reach the voltage threshold during a triggering time after the stepwise reduction of the current limit.
