A soft start panel is a control system that reduces the amount of torque delivered to the power train of an AC electric motor. In an electric application, the soft starter temporarily reduces the current input or voltage. It has wide range of applications both in low as well as in high supply regions. A soft starter eliminates the undesired side effects. Several types based on control of the supply voltage or mechanical devices such as slip clutches were developed. The list provides an overview of the various electric  start-up types. The current and torque characteristic curves show the behavior of the respective starter solution. Torque surges entail high mechanical stress on the machine, which results in higher service costs and increased wear. High currents and current peaks lead to high fixed costs charged by the power supply companies (peak current calculation) and to increased mains and generator loads.
