Product information

The EWSKD 31.8 3x100/5A 2,5VA Kl.0,5s is a compact, high-precision low-voltage measuring transformer of the proven EWSKD series, specially developed for use in power distribution, switchgear, meter panels and industrial measuring and monitoring systems.

Technical main features:
  • Type Window-type current transformer – EWSKD 31.8
  • Transformation ratio 3x100/5 A (three primary windings of 100 A each, rated secondary current 5 A)
  • Rated power / burden 2,5 VA
  • Accuracy class accuracy class 0,5 s (according to IEC/EN 61869-2 or DIN EN 61869-2)
  • Primary conductor bore Window opening 31 × 8 mm (for busbar or cable)
  • Maximum operating voltage Um ≤ 0,72 kV
  • Rated frequency 50–60 Hz
  • Thermal rated continuous current Icth = 1,0 × Ipr (continuous current 1 × rated primary current)
  • Thermal rated short-time current Ith = 60 × Ipr, 1 s
  • Insulation class E
  • Insulation test voltage 3 kV, 50 Hz, 1 min
  • Mounting Rail and wall mounting possible

The EWSKD 31.8 3x100/5A 2,5VA Kl.0,5s is characterised by its very compact design with integrated 3-channel design, high reliability and excellent linearity – ideal for applications where precise three-phase measurement is required at medium currents (e.g. distributions, measuring stations, energy monitoring systems with moderate power requirements).

We are happy to supply this model from stock at short notice or configure further primary currents of the EWSKD series for you.
