Product Overview

The 3RW3027-1BB14 is a Soft Starter reduces the motor voltage through variable phase control and increases it in ramp-like mode from a selectable starting voltage up to mains voltage. During starting, this device limit the torque as well as the current and prevent the shocks which arise during direct starts or wye-delta starts. In this way, mechanical loads and mains voltage dips can be reliably reduced. Soft starting reduces the stress on the connected equipment and results in lower wear and therefore longer periods of trouble free production. The selectable start value means that the soft starter can be adjusted individually to the requirements of the application in question and unlike wye-delta starter is not restricted to two-stage starting with fixed voltage ratios. It is characterized above all by its small space requirements. Integrated bypass contacts mean that no power loss has to be taken into the bargain at the power semiconductors after the motor has started up.
  • Soft starting and smooth ramp-down
  • Stepless starting
  • Reduction of current peaks
  • Avoidance of mains voltage fluctuations during starting
  • Reduced load on the power supply network
  • Reduction of the mechanical load in the operating mechanism
  • Considerable space savings and reduced wiring compared with conventional starters
  • Maintenance-free switching
  • Very easy handling
  • Fits perfectly in the SIRIUS modular system
