EWSK 31.5 100/1A 10VA Kl.0,2
Product information
The EWSK 31.5 100/1A 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.
Key technical features:- Type window current transformer (Window-Type) – EWSK 31.5
- Transformation ratio 100/1 A (primary rated current 100 A, 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 Window opening for busbars up to 31 mm × 12 mm or round conductors up to Ø 30 mm
- 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
