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.

Motor starter, operating method, computer program product and motor starter arrangement

An electrical apparatus includes a top-hat rail mount and a first conductor connection with a clamping point. A conductor can be secured via the clamping point. The electrical apparatus can be connected to a top-hat rail via a rotational movement about a rotational axis at the top-hat rail mount. In an embodiment, the first conductor connection be embodied and arranged in such a way that in the state in which the apparatus is connected to the top-hat rail via its top-hat rail mount, the longitudinal axis of a straight conductor which is accommodated in the first conductor connection is located essentially perpendicularly with respect to a straight line which is oriented orthogonally with respect to the rotational axis and which intersects the rotational axis and the clamping point.
