SIRIUS 3RW55 soft starter High Performance
Equipped with the utmost functionality, the SIRIUS 3RW55 High Performance soft starters confidently handle even difficult starting and stopping operations. Integrated smart functions (for example, pump cleaning, pump stopping, automatic parameterization, condition monitoring) help operators to run their pumps smoothly. Thanks to innovative torque control, the device can be used for drives with an output of between 5.5 kW and 1 200 kW (at 400 V). The innovative 3RW55 Failsafe soft starter has an integrated fail-safe digital input to directly connect the EMERGENCY STOP, thus covering SIL 1 STO applications. The HMI (with color display, local interface and a slot for micro SD memory card) and plug-in communications modules (PROFINET, PROFIBUS, EtherNet/IP and Modbus) ensure maximum flexibility. With their modern hybrid switching technology, the SIRIUS 3RW55 soft starters offer efficient switching for long-term, energy-saving use.
