This listing is for 1. SIEMENS SIRIUS 3RW3038-1BB04 SOFT STARTER , MOTOR STARTER 72A, 37kW, 40HP. SIRIUS soft starter S2 72 A, 37 kW/400 V, 40 °C 200-480 V AC, 24 V AC/DC Screw terminals.Siemens 3RW3038-1BB04 62 AMP, 20 H. These 3RW3 Sirius Soft Starters are for use in. Asynchronous motors in such applications as heat pumps, hydraulic pumps, presses and conveyors. The SIRIUS Siemens 3RW3038-1BB04 soft starters reduce the motor voltage through variable phase control and increase it in ramp-like mode from a selectable starting voltage up to mains voltage. During starting, these devices limit the torque as well as the current and prevent the shocks which arise during direct starts or wye-delta starts.
In this way, mechanical loads and mains voltage dips can be reliably reduced. Soft starting reduces the stress on the connected equipment and results in lower wear and therefore longer periods of trouble free production.The selectable start value means that the soft starters can be adjusted individually to the requirements of the application in question and unlike wye-delta starters are not restricted to two-stage starting with fixed voltage ratios. The SIRIUS Siemens 3RW3038-1BB04 soft starters are characterized above all by their small space requirements. Integrated bypass contacts mean that minimal power loss is used at the power semiconductors (thyristors) after the motor has started up. This cuts down on heat losses, enabling a more compact design and making external bypass circuits superfluous.
