AC Soft Starter 250kW have the following Main Features:

AC Soft Starter 250kW can work with three-phase, AC squirrel cage induction asynchronous motor, The voltage is 320V~460V, 50HZ/60HZ and the current is 1200A and below. The soft starter is a device type. It's necessary to add breakers (short-circuit protection ) and AC contactor (Bypass) inside the cabinet. Together with switches are made up of electric motor control circuit.

AC Soft Starter 250kW can work without three-phase AC motor in the process of starting too big acceleration torque, and power supply system plays a protection from excessive current harvest dynamic impact role,


Through controlling the conductive angle of three phase anti-parallel thyristor that is connected in series between power supply and the controlled motor. AC Soft Starter 250kW make the terminal voltage of motor rise to the rated voltage from the preset value. Reaching the aim of smooth starting by reducing current during the starting process. It belongs to the category of reduced-voltage starting. Hence. Starting torque would be reduced somewhat. It is suitable for locations where are not strict with starting torque. In order to obtain the optimum efficiency of AC Soft Starter 250kW.

Scope of application for AC Soft Starter 250kW.

AC Soft Starter 250kW applies to centrifuges, blower, compressor, transport planes, mixer, rolling ball mill broken machines and mechanical equipment motor starter.
