Product description
Soft starter Siemens SIRIUS 3RW4028-1BB14
The SIRIUS soft starter 3RW4028-1BB14 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 3RW4028-1BB14 ideal for the start-up of motors up to 18.5 kW at a control voltage of 110-230 V AC/DC. The soft starter also provides integrated supplementary functions like settable current limiting, motor overload and intrinsic device protection. The main fields of application of the soft starter 3RW4028-1BB14 are pumps, conveyors, agitators and milling machines.
