Functions and features

RCM (Residual Current Monitoring)

  • Continuous monitoring of residual currents (Residual Current Monitor, RCM)
  • Alarming in case a preset threshold fault current reached
  • Near-realtime reactions for triggering countermeasures
  • Permanent RCM measurement for systems in permanent operation without the opportunity to switch off
  • Ideal for the central earthing point in TN-S systems

High quality measurement

  • Constant true RMS measurement
  • Measurement process in accordance with IEC 61000-4-30
  • Certified accuracy of measurement according to class A
  • Continuous sampling of the voltage and current measurement inputs at 25,6 kHz
  • 512 measurement points per period
  • Recording of over 2,000 measured values per measurement cycle
  • Accuracy of active energy measurement: Class 0.2S
  • Fast measurement even enables the logging of rapid transients from 39 µs
  • Logging of currents and voltages (15 – 440 Hz)

User-friendly, colour graphical display with intuitive user guidance

  • High resolution colour graphical display 320 x 240, 256 colours, 6 buttons
