Description SIEMENS Soft Starter 3RW30/3RW40
The electronic soft starters 3RW from the SIRIUS system modular kit are designed for smooth starting as well as acceleration and deceleration of three-phase motors. They protect the mechanical power transmission elements of the machine during startup by reducing the starting torque and efficiently safeguard the network from dangerous peaks through reduced current consumption. By continuously increasing the motor voltage, the network, motor, and load are preserved and optimally protected against overload.
The 3RW soft starters are narrow (45 or 55 mm), cost-effective, and can be easily combined with SIRIUS contactors, circuit breakers, and overload relays.
Features: 3RW30: Optimal adaptation to the drive task through individual potentiometers for starting voltage (40...100%) and ramp-up time up to 20 s, soft starting only, space-saving installation with simple 4-wire motor connection, 70% space savings compared to star-delta combinations, control supply voltage 110 - 230V AC/DC.
