NATUS highlights

DTS

Patented contact mechanism, double transfer system for safe isolation of the withdrawable unit

  • Highly functional withdrawable unit technology
  • Safe isolation of the power circuits (back) and control circuits (right) via a mechanical contact process using the operating handle (front)
  • Can only be operated when the door is shut, for safety reasons
  • High operational safety via operator guidance and locks
  • Simultaneous isolation of the power circuits, input and output side
  • Provision of operational, test and isolation setting
  • No connected cable movement (prevents splaying)
  • Internal arc-protected zone in combination with ARC-SAFE distribution busbar

ARC-SAFE

The safe distribution busbar for withdrawable unit and plug-in technology

  • Complete, automatic cover of the live phases by the automatic shutter
  • Highest internal arc safety via complete enclosure and isolation of the phases from one another
  • Internal arc-protected zone in combination with DTS contact system
  • Enables modification of the system when live
  • IP4X operator protection when door is open
  • Also available in fuse block
