  • Speeds up installation, maintenance and testing of the protection..
  • Contributes to shortened MTTR (mean time to recover).
  • Allows the cases to be installed and wired before the plug-in units are delivered.
  • Prevents the insertion of a wrong plug-in unit in a case thanks to a mechanical coding system.
