SIRIUS Soft Starter, 38 Amps, 18.5 kW, Size S0

This capable SIRIUS 3RW40 soft starter is suitable for tasks including motor starting, reduction of current peaks, prevention of supply voltage fluctuations during start-up, reduction of load on the power supply network, reduction of mechanical load in the drive. These versatile drives also save space and wiring time when compared to star-delta (wye-delta) starters and frequency converters, providing maintenance-free switching.

The integrated bypass facilitates a very compact construction and ensures low heat dissipation in the control cabinet. Intelligent monitoring functions protect the soft starter against overheating and the motor against overload. In addition, you can limit the current during start-up to a settable maximum value.

With the integrated remote reset, you can quickly and easily clear faults from a remote location and with worldwide approvals (IEC and UL/CSA), these starters are also for applications in hazardous areas (ATEX or IEC Ex).

The 3RW soft starters are available for supply systems up to 690V in a wide performance range with different control supply voltages and all with both screw and spring-type terminals.

With the optional link module, the soft starters can be attached to the circuit breakers, even for the versions with spring-type terminals. The optional fan permits an even more compact design in the control cabinet.
