The 3RW5 family of soft starters is a comprehensive soft starter portfolio that has been developed for a wide range of applications and is simple to select, install, and configure. These starters are ready for the Internet of Things (IoT), being easily integrated into most industrial communication networks. Communications via Profinet, Modbus and Ethernet IP, along with HMI panels, are available across the entire product range. Whether your motor application is for pumping, fans, or crushing, the 3RW5 soft starters can handle each and every load; giving you peace of mind.
Thanks to comprehensive and specific functions, our powerful, coordinated portfolio of soft starters is suitable for a wide range of applications.
No matter which industry you work in, take advantage of intelligent functions such as condition monitoring, automatic parameterization, pump cleaning, and integrated brake functions.
Hybrid switching technology combines the advantages of electronic control with power semiconductors and the low conducting losses of switching contacts. The strengths of each technology are exploited during the appropriate operating phase.
As the motor starts, the soft starter is operated via the power semiconductors, which enable precise and targeted control of the starting current. After the motor has been softly started using semiconductors, the low-loss switching contacts take over the current until the motor is switched off.
The hybrid switching technology ensures a longer service life for switchgear due to the reduced wear when switching on.
The digital transformation of industry is in full swing and our latest generation of soft starters supports companies in fully embracing the potential of digitization. The Simulation Tool for Soft Starters (STS) helps users to easily select devices for their application.
The SIRIUS Soft Starter ES software in the Totally Integrated Automation Portal (TIA Portal) enables you to quickly and easily perform parameterization (3RW55) and monitoring as well as diagnostics in the event of servicing SIRIUS general and high performance soft starters. The device parameters can be set directly on a PC and transferred to the soft starter via Ethernet cable or a PROFIBUS/PROFINET connection.
Connecting our soft starters to MindSphere, our cloud-based, open IoT operating system, gives you further options; cross-plant diagnostics, convenient process optimization, plant-wide access to control data, as well as process and measured values, predictive maintenance, energy data management, and resource optimization.
With the Simulation Tool for Soft Starters (STS), we provide a convenient way to design soft starters using a simple, quick, and user-friendly interface. You just need to enter the motor and load data to simulate the application. The tool then suggests suitable soft starters.
SIRIUS Soft Starter ES is the central software for project planning, commissioning, operation, and diagnosis of the SIRIUS 3RW5 general and high performance soft starter series.
SIRIUS Soft Starter ES is seamlessly integrated into the central Totally Integrated Automation Portal (TIA Portal) Engineering Framework, thus providing users with a consistent, efficient, and intuitive solutions for all their automation tasks.
