Siemens 3RW4056-2BB45 Soft starter SIRIUS 3RW40

Siemens Sirius 3RW40 is intended for high power 250 Kilowatt asynchronous engines. Siemens Soft starter give easily start, protects the motor against overload, reduces power rate, which do the utilize of apparatus cheaper. The data devices apply features unique to this capacity range: solid-state motor overload protection and inbuilt protection devices, adjustable current limitative and control the 2-phase technique (polarity balance). The soft starter Siemens 3RW40 are part of the SIRIUS modular system. Consequently, they have pinpoint sizes and wiring schemes. Thanks to their special dense dimensions, Siemens soft starters are half as much the size of star-delta starters, thus they take up minimum space in the control cabinet. At the contactor, they are utilized as protective infinite conjunction for starting engines.
