SIRIUS soft starter 200-480 V 38 A, AC/DC 24 V screw terminals Failsafe soft starter Failsafe SIRIUS 3RW55 High Performance for demanding safety applications for the gentle starting and stopping of three-phase asynchronous motors. Stepless starting, reduction of current peaks, avoidance of mains voltage fluctuations during start-up, relief of the power supply network, reduction of mechanical load in the drive, considerable space and wiring savings compared to star-delta starters and frequency converters, maintenance-free switching and extremely easy handling. The integrated bypass enables the very compact design, saves energy and ensures less heating in the control cabinet. Intelligent monitoring functions protect the soft starter from overheating and the motor from overload. You can also limit the current to an adjustable maximum value during start-up. Thanks to 3-phase control, particularly suitable for high motor outputs. The innovative torque control ensures optimum motor start-up. Simple and quick commissioning through automatic parameterization or application assistant. Predictive maintenance planning through condition monitoring. Removable HMI with color display for clear measured value and diagnostic displays. Worldwide approvals (e.g. IEC and UL/CSA) also for potentially explosive applications (ATEX or IEC Ex).The high-performance soft starters Failsafe 3RW55 are available for networks up to 600 V in a power range up to 315 kW with 24 V or 110-250 V control supply voltages and consistently with screw and spring-loaded connections. Analog output and thermistor motor protection are an integral part of the high-performance soft starters.Optional plug-in communication modules enable connection via PROFINET, PROFIBUS and Modbus TCP. The built-in HMI module can also be mounted in the control cabinet door.Soft starter SIRIUS 3RW5 - as flexible as your task.
