Soft starter Siemens SIRIUS 3RW3028-1BB04
The SIRIUS soft starter 3RW3028-1BB04 from Siemens reduces the motor voltage through variable phase angle control and increases it in ramp-like mode from an adjustable start-up voltage up to the line voltage. This makes the soft starter 3RW3028-1BB04 ideal for the start-up of motors up to 18.5 kW at a control voltage of 24 V AC/DC. The main fields of application of the soft starter 3RW3028-1BB04 are pumps, conveyor belts and screw conveyors.
