INFORMATION

Description

Electronic residual current current protection and monitoring relay (IEC 62020) compatible with the protection transformers of the WGC-TB series. The RGU-10B is the most complete system for monitoring and controlling electrical insulation of type-B installations (IEC 60755).

  • Electronic relay with relay output.
  • Measures in AC, DC or mixed current, type B (IEC 60755)
  • Measures the intensity of the current by connecting to an residual current transformer of the WGC-TB
  • Programmable with backlit LCD display:
    • Trip current (red display when tripped)
    • Parameter programming
    • Instantaneous leakage current
    • Disconnection of external transformer
  • Status signalling via 2 LEDs
  • Features two independent programmable outputs (main and prealarm).
  • Includes a remote-control input.
  • Assembly on DIN 46277 rail (EN 50022), 3 modules.

Applications

Monitoring of the electrical insulation in:

  • Single or three-phase AC installations, AC installations with DC components or purely DC installations. With frequencies of up to 1 kHz.

Such as, for example:

  • Speed drives
  • UPS (Uninterruptible Power Supply systems)
  • Photovoltaic installations
  • Motor control devices, etc.
