Soft starter SIRIUS 3RW40

The Sirius 3RW40 soft starter is designed for high power asynchronous engines (250 kW). Siemens Soft starter give easy start-up, protects the motor against overload, lower power rate, which do the use of devices low-priced. The data models use features unusual to this energy range: solid-state engine overload defense and inbuilt appliance defense, adjustable current limiting and control the two-phase method. The Soft starters 3RW40 are part of the SIRIUS modular system. As a result, they have identical sizes and wiring diagrams. Thanks to their especially compact size, SIRIUS 3RW40 soft starters are half the dimension of star-delta starters, so they take up minimal place in the switch cabinet. Together with the contactor, they are used as protective infinite conjunction for electric engines.
