3RW3028-1BB14 SIEMENS

The SIRIUS 3RW3028-1BB14 soft starter is a compact and efficient solution for smoothly starting three-phase asynchronous motors. This soft starter is designed for size S0 and is rated for a current of 38 A. It is suitable for motors with a power rating of up to 18.5 kW at 400 V and an ambient temperature of 40 °C. The device operates within a voltage range of 200-480 V AC and features a control supply voltage of 110-230 V AC/DC, offering flexibility in various power environments. The 3RW3028-1BB14 utilizes screw terminals for secure and reliable electrical connections. By reducing the starting current and torque, this soft starter minimizes mechanical stress on the motor and driven equipment, extending their lifespan. It also prevents voltage dips in the power supply during motor startup. This soft starter provides a cost-effective and space-saving alternative to traditional starting methods like star-delta starters. Its integrated bypass function further reduces energy consumption during normal operation. The SIRIUS 3RW3028-1BB14 soft starter is an ideal choice for applications requiring smooth and controlled motor starting.
