The Siemens 3RW3036-1BB04 is a SIRIUS 3RW30 basic performance soft starter with integrated bypass, designed for the smooth starting and ramp-down of three-phase asynchronous motors. It controls two phases via voltage ramp, reducing mechanical stress on drive systems, electrical stress on motor windings, and current peaks during startup. Rated for 45 A and 22 kW (30 HP at 460 V), it operates on a three-phase supply of 200–480 V AC at 50/60 Hz and uses a 24 V AC/DC control supply. The integrated bypass contacts minimize heat dissipation during continuous operation, eliminating the need for an external bypass contactor. Typical applications include pumps, fans, conveyors, and compressors. The unit features screw-type terminals, DIN rail or screw mounting, and offers compact dimensions suitable for control cabinet installations in industrial automation environments.
