SIRIUS soft starter 200-480 V 38 A, 110-250 V AC, spring-type terminals Fail-safe Failsafe soft starters SIRIUS 3RW55 High Performance for demanding safety applications for soft starting and stopping of three-phase asynchronous motors. Soft starting, reduction of current peaks, prevention of supply voltage fluctuations during startup, reduction of load on the power supply network, reduction of mechanical load in the drive, considerable saving of space and wiring compared to star-delta (wye-delta) starters and frequency converters, maintenance-free switching and extremely easy handling.The integrated bypass allows a very compact construction, saves energy 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 startup to a settable maximum value. Thanks to 3-phase control, particularly suitable for high motor outputs. The innovative torque control ensures ideal motor startup. Simple and fast commissioning by means of auto-parameterization or application wizard. Predictive maintenance planning due to condition monitoring. Detachable HMI with color display for clear presentation of measured values and diagnostics. Worldwide approvals (e.g. IEC and UL/CSA), also for applications in hazardous areas (ATEX or IEC Ex). The High Performance 3RW55 Failsafe soft starters are available for supply systems up to 600 V in a performance range up to 315 kW with 24 V or 110-250 V control supply voltages and all with both screw and spring-type terminals. Analog output and thermistor motor protection are fixed components of the High Performance soft starter. Optional plug-in communication modules allow connection via PROFINET, PROFIBUS and Modbus TCP. The built-in HMI module can also be mounted in the control cabinet door. SIRIUS 3RW5 soft starters - As flexible as your tasks.
