Switching arrangement for regulation and delimitation of power input, particularly start-up phase of three-phase alternating current or alternating-current motor, comprises switching unit, which is connected upstream in phase in series

摘要

The switching arrangement comprises a switching unit (1) of a motor (2), which is connected upstream in a phase in series and over a current limiting resistance unit (3). A control or program unit is provided for clock bridging of the resistance unit by an electronic switch (5) corresponding to the power input of the motor.
