Siemens 3RW52 Soft Starter 480V AC, 400 kW, 3 Phase 3RW5247-6TC14

Siemens 3RW5247-6TC14 Soft Starter is a high-performance device rated at 400 kW with a 480V AC supply voltage designed for smooth starting and stopping of three-phase asynchronous motors in industrial environments.

This soft starter efficiently reduces current peaks and prevents supply voltage fluctuations, thereby enhancing the stability of the power network. It also limits mechanical load during motor startup, ensuring longer equipment life and reduced maintenance.

The product incorporates an integrated bypass that contributes to a compact design and minimizes heat dissipation within control cabinets. The intelligent monitoring functions safeguard the soft starter against overheating and protect motors from overload, enhancing operational safety and reliability.

With three-phase control, the device is particularly suited for high motor power applications and inside-delta circuit configurations. The innovative Soft Torque function guarantees a gentle motor start, helping to reduce mechanical stress. The integrated remote reset feature allows faults to be cleared quickly and conveniently from remote locations.

Multiple communication options are supported through optional plug-in modules, including PROFINET, PROFIBUS, EtherNet/IP, and Modbus TCP, enabling seamless integration into modern industrial automation systems. Various HMI modules are available for installation on the device or control cabinet door to facilitate easy operation.
