Product information

The EWSKD 31.8 3x75/5A 2,5VA Kl.0,2 is a compact, high-precision three-phase window-type current transformer of the proven EWSKD series, specially developed for use in power distribution, switchgear, meter panels and industrial measurement and monitoring systems.

Technical main features:
  • Type window-type current transformer (Window-Type) – EWSKD 31.8, 3-phase
  • Transformation ratio 3x75/5 A (primary rated current 75 A per phase, secondary rated current 5 A)
  • Rated power / burden 2,5 VA
  • Accuracy class Kl. 0,2 (according to IEC/EN 61869-2 or DIN EN 61869-2)
  • Primary conductor bore For busbars up to max. 31 mm × 8 mm (window bore)
  • Maximum operating voltage Um ≤ 0,72 kV
  • Rated frequency 50–60 Hz
  • Thermal rated continuous current Icth = 1,0 × Ipr (continuous current 1 × primary rated 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 foot mounting possible

The EWSKD 31.8 3x75/5A 2,5VA Kl.0,2 is characterised by its very compact design, high reliability and excellent linearity – ideal for applications where high-precision measurement in three-phase systems is required at medium currents (e.g. distributors, 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.
