APPLICATION

The ExxxE residual current sensor is a non-conventional, passive split core sensor for retrofit installation over all three cables of gas- or air-insulated switchgear in primary or secondary energy distribution. Its large Big ECO Shape E aperture opens to fit around existing three-phase cable sets, delivering a very high cost-benefit ratio. Designed to IEC 61869-1 and IEC 61869-10.

PRODUCT ADVANTAGES

  • Non-conventional passive technology – no active parts, no power supply required
  • Splitable form factor for retrofit installation
  • Large inner diameter for residual current measurement over 3 phases
  • Cost-effective construction with a high cost-benefit ratio
  • Correction factors for amplitude and phase improve the accuracy class (base 3/1, up to 0.5)
