Soft starter SIRIUS 3RW30

The soft starter SIRIUS 3RW30 is specially destined for three-phase motors of the asynchronous type with a power does not exceed 55 kW. The soft starter has an ample set of variation to easily start the motor. SIRIUS soft starter devices give easy working of the linked motors, reducing the starting torque. The capacity supply is defended from dangerous crests by reducing current consumption during startup. Together with the contactor, they are utilized as safety-free starting combinations for electric motors. Siemens 3RW30 electronic soft starters from the SIRIUS modular system: small, inexpensive and easy to combine with SIRIUS overload relays. The Sirius 3RW allow soft start and stop for 3-phase asynchronous engines. The hitherto used starter switching from star to delta, such as mixers, grinders, textile machines, and so on.
