Electronic earth leakage current intensity monitoring relay (IEC 62020), compatible with the WGC-TB series protection transformers. The RGU-10B is the most complete system of the range that monitors and controls the electrical insulation of B type installations (IEC 60755).

  • Electronic relay with relay output.
  • Measures in AC, DC or mixed current, type B (IEC 60755)
  • Measures the current’s intensity when connected to an earth leakage transformer of the WGC-TB series.
  • Programmable with backlit LCD display
  • Current trip (red display when triggered)
  • Parameter programming
  • Instantaneous leakage current
  • Disconnection of external transformer
  • Status signalling with 2 LEDs
  • It has two independent programmable outputs (main and prealarm).
  • It has a remote control input.
  • Assembly on DIN rail 46277 (EN-50022).
  • 3 modules
