Product information

The ring core current transformer EWSK 31.5 100/5 A 10 VA Kl. 0,5 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.

Main technical features:
  • Type ring core current transformer – EWSK 31.5
  • Transformation ratio 100/5 A (primary rated current 100 A, secondary rated current 5 A)
  • Rated power / burden 10 VA
  • Accuracy class Kl. 0,5 (according to IEC/EN 61869-2 or DIN EN 61869-2)
  • Primary conductor bore For round conductors up to max. Ø 31 mm (cable entry)
  • 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 = 100 × Ipr, 1 s
  • Insulation class E
  • Insulation test voltage 3 kV, 50 Hz, 1 min
  • Dimensions (approx.) Width 82 mm × height 82 mm × depth 42 mm
  • Weight (approx.) 0,6 kg (depending on version)
  • Mounting Foot and rail mounting possible, including insulating protective cap

The [product name] is characterised by its robust ring core design, high reliability and excellent linearity – ideal for applications where precise measurement is required at medium currents (e.g. medium distribution boards, measuring stations, energy monitoring systems with higher power requirements).

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