Product information

The window-type current transformer EWSK 31.5 40/1A 10VA Kl.0,2 is a compact, high-precision low-voltage measuring transformer of the proven EWSK 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) – EWSK 31.5
  • Transformation ratio 40/1 A (primary rated current 40 A, secondary rated current 1 A)
  • Rated power / burden 10 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 DIN rail and foot mounting possible

The [product name] is characterised by its very compact design, high reliability and excellent linearity – ideal for applications where a high-precision measurement is required at relatively low currents (e.g. smaller distribution boards, measuring stations, energy monitoring systems with moderate power requirements and secondary current 1 A).

We will be happy to supply this model from stock at short notice or configure further primary currents of the [EWSK] series for you.
