Product information

The EWSKD 31.8 3x50/1A 5VA Kl.0,2 is a compact, high-precision low-voltage measuring transformer from 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 current transformer (Window-Type) – EWSKD 31.8
  • Transformation ratio 3x50/1 A (primary rated current 50 A per phase, secondary rated current 1 A)
  • Rated power / burden 5 VA
  • Accuracy class accuracy class 0,2 (according to IEC/EN 61869-2 or DIN EN 61869-2)
  • Primary conductor bore For round conductors up to max. Ø 31 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 Foot and rail mounting possible, including insulating protective cap

The EWSKD 31.8 3x50/1A 5VA Kl.0,2 is characterised by its very compact design, high reliability and excellent linearity – ideal for applications where high-precision measurement is required in three-phase systems (e.g. meter installations, 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.
