Abstract

A motor starter for operating an electric motor connected to a multiphase power supply includes a semiconductor switch arranged in a current-carrying phase of the multiphase power supply, and an electromechanical switch arranged in parallel relation to the semiconductor switch in the current-carrying phase. The electromechanical switch includes a movable switching piece configured tiltable to reduce a current gradient in the semiconductor switch.
