Siemens SIRIUS 3RW Soft Starter, 315 kW, 480 V ac, 3 Phase

Reduce strain on your mechanical equipment by installing this Siemens soft starter. When first turned on, motors receive an initial rush of energy which can affect voltage supply. To prevent potential damage, this unit regulates the startup voltage, so it's gradually delivered until complete acceleration is achieved. A current rating of 315kW ensures seamless transmission from one phase to another, even under voltages as high as 400V. Rely on this soft starter in your motorised installations to regulate the power-up process and ensure smooth activation.

• 393 (H) x 210 (W) x 203mm (D) for convenient installation in tight spaces
• Reliable LED (light-emitting diode) signalling system for easy diagnosis
• Power-up ramp time between 0 and 20 seconds for swift but steady acceleration that prevents breakdowns
• Torque-control capability minimises the risk of wear and tear

This device can be modified to feature a communication module by connecting it to a standard PROFINET, PROFIBUS or Modbus transmission control protocol. This enables connection to external devices like laptops that can be used to remotely monitor its state and adjust its settings.
