The Sirius soft starter, rated up to 250 kW, is designed for standard three-phase applications and provides soft on/off control for 3-phase asynchronous motors, avoiding current peaks and torque associated with star-delta starters. It incorporates a bypass contact system to minimize power losses and prevent overheating of components. The overload tripping time can be adjusted via a 4-step rotary switch, and adjustable current limitation protects the motor from sudden amperage increases. Three LEDs indicate potential errors, ineffective trip times, phase failure, and overheating. Primary applications include fans, presses, assembly lines, chillers, centrifuges, and mixers.
