Wega 2.2 C

Integrated voltage detecting system with display and remote signalling

Wega 2.2 C is a 3-phase voltage detecting system, which indicates the following operating voltage states:

Additional to the LCD display the Wega 2.2 C has two LEDs (green U=0 and red U≠0). With two relay contacts the voltage state can be remotely monitored.

The built-in display test function at the front enables verification of the display of the installed and de-energised Wega 2.2 C.

For connection, either shielded or unshielded cables with flat connectors or system connectors can be used.

  • Designed according to IEC 61243-5 (VDE 0682-415)
  • Remote: two relay contacts
  • Wide-range Wega (e.g. 10 – 20 / 24 kV): Reduction of variants
  • Integrated maintenance test: maintenance-free
  • Retrofit ready: connection to ComPass B and Sigma D series
  • Front accessible LRM interface: fully featured according to IEC 61243-5
  • Fully enclosed electronics: high functional reliability
  • Overvoltage indication: phase-selective
