Belt slip on heater blowers or a sudden buildup of water pressure in washing installations are only two of the many problems that can occur when motors generate too much power on starting. With the SIRIUS 3RW30 from 1.5 kW to 55 kW (at 400 V) you can easily avoid such problems. And the best of it all is: It is also possible to switch straight from direct to soft start because SIRIUS 3RW30 is the only soft starter in the world that offers identical sizes in a family of devices.
