Abstract: An electronic switch includes switching modules to change a forward resistance of a semiconductor switch via a drive circuit depending on data exchanged via a data interface and depending on measurement values of a current sensor. The semiconductor switches of the switching modules are arranged electrically in parallel and a current through the electronic switch is divided among the semiconductor switches. The electronic switch controls a division of the current through the electronic switch among the semiconductor switches via the drive circuits by changing a forward resistance of the semiconductor switches, synchronously switches the semiconductor switches via the drive circuit and operates the semiconductor switches in a linear region in a time range of 1 ?s to 10 ?s upon a change between ON and OFF and a change between OFF and ON in such a way that the current through the switching modules is reduced in a controlled manner.

Abstract: A motor starter and a method for starting an electric motor are disclosed. In an embodiment, the motor starter includes a phase gating unit and a control unit. The phase gating unit is configured to be deactivated via the control unit after an activity period of the phase gating unit has elapsed and is configured to be deactivated during operation after the activity period has elapsed.
