Product Description
The Siemens 3RW52 Soft Starter 3RW5227-1AC04 is engineered for effective and reliable control of three-phase asynchronous motors, providing smooth starting and stopping. Designed for applications up to 90 kW, this soft starter operates at a maximum supply voltage of 480V AC and supports installations requiring screw fixing.
Key features include its IP00 protection rating for use within protected panels or enclosures. The compact construction integrates a bypass relay, minimizing heat dissipation and maximizing energy efficiency within control cabinets. Intelligent monitoring functions protect the soft starter from overheating and ensure motor overload protection. The unit supports analog outputs and remote reset - allowing convenient fault clearing from remote locations. The soft torque function ensures gentle motor startup, reducing mechanical stress and prolonging system life.
Siemens SIRIUS 3RW52 soft starters stand out for their easy parameterization using rotary potentiometers, facilitating quick commissioning. Their three-phase control capability is particularly suited for high-output motors and inside-delta circuits. They are maintenance free, with extremely simple handling, and offer considerable savings compared to traditional star-delta starters and frequency converters.
Optional plug-in communication modules expand connectivity with PROFINET, PROFIBUS, EtherNet/IP, and Modbus TCP, along with HMI modules for device or cabinet door installation. The design complies with IEC 60529, IEC 60947-4-2, UL, CSA, EAC, and CCC approvals, supporting global operational requirements.
