3RW4037-2BB14 SIEMENS

The SIRIUS 3RW4037-2BB14 soft starter is a highly reliable and efficient solution for smoothly starting three-phase asynchronous motors. This particular model is an S2 size soft starter, designed for motors with a rated operational current of up to 63 A. It is suitable for motors with a power rating of up to 30 kW when operating at 400 V and an ambient temperature of 40 °C. The device can be used with a wide range of supply voltages, from 200 to 480 V AC, making it adaptable to various power grids. The control voltage is also flexible, accepting both 110-230 V AC and DC. This soft starter utilizes spring-type terminals, ensuring secure and vibration-resistant connections, which are crucial in industrial environments. By reducing the starting current and mechanical stress on the motor and driven equipment, the 3RW4037-2BB14 extends the lifespan of the entire system. It offers adjustable parameters for optimizing the starting and stopping characteristics of the motor, enhancing process control and minimizing downtime. Furthermore, the integrated bypass function minimizes power losses during normal operation, contributing to energy savings.
