Product information

The EWSKD 31.8 3x150/1A 10VA Kl.0,2 is a compact, high-precision low-voltage measuring current transformer of the proven EWSKD series, specially developed for use in power distribution, switchgear, meter panels and industrial measurement and monitoring systems.

Key technical features:
  • Type window current transformer (Window-Type) – EWSKD 31.8
  • Transformation ratio 3x150/1 A (primary rated current 150 A per phase, secondary rated current 1 A)
  • Rated power / burden 10 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 × 8 mm (busbar bore)
  • Maximum operating voltage Um ≤ 0,72 kV
  • Rated frequency 50–60 Hz
  • Rated continuous thermal current Icth = 1,0 × Ipr (continuous current 1 × primary rated current)
  • Rated short-time thermal current Ith = 60 × Ipr, 1 s
  • Insulation class E
  • Insulation test voltage 3 kV, 50 Hz, 1 min
  • Dimensions (approx.) Width 60 mm × height 80 mm × depth 40 mm
  • Weight (approx.) 0,5–0,7 kg (depending on version)
  • Mounting Foot and rail mounting possible, including insulating protective cap

The [EWSKD 31.8 3x150/1A 10VA Kl.0,2] is characterised by its very compact design, high reliability and excellent linearity – ideal for applications where high-precision measurement is required at medium currents (e.g. 3-phase 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.
