3RW5055-2AB04 SIEMENS

The SIRIUS 3RW5055-2AB04 soft starter is designed for motors operating between 200-480V and is suitable for applications requiring a current of up to 143A. This soft starter provides a gentle start and stop for three-phase asynchronous motors, minimizing mechanical stress and voltage dips. It features 24 V AC/DC spring-type terminals for reliable and vibration-resistant connections. The integrated analog output provides a signal proportional to the motor current or voltage, enabling easy monitoring and control. This soft starter offers adjustable starting voltage, current limiting, and ramp-up/ramp-down times for customized motor control. It also includes built-in protection functions such as overload, phase failure, and overtemperature protection, ensuring motor and starter safety. The compact design allows for space-saving installation in control cabinets. The 3RW5055-2AB04 contributes to increased energy efficiency by reducing starting currents and minimizing mechanical wear. It is ideal for pumps, fans, compressors, and other applications requiring smooth and controlled motor starting and stopping.
