Soft starter Siemens SIRIUS 3RW4026-1BB04
The SIRIUS soft starter 3RW4026-1BB04 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 3RW4026-1BB04 ideal for the start-up of motors up to 11 kW at a control voltage of 24 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 3RW4026-1BB04 are pumps, conveyors, agitators and milling machines.
