EWSK 31.5 40/1A 2,5VA Kl.0,2
Product information
The EWSK 31.5 40/1A 2,5VA Kl.0,2 is a compact, high-precision low-voltage measuring current transformer from 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 2,5 VA
- Accuracy class Kl. 0,2 (according to IEC/EN 61869-2 or DIN EN 61869-2)
- Primary conductor bore Window opening 30 x 31 mm (for busbar conductors)
- 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
- Mounting Clip-on mounting for rails and busbars, including secondary terminals
The EWSK 31.5 40/1A 2,5VA Kl.0,2 is characterised by its very high accuracy class 0,2, compact design and excellent linearity – ideal for applications where particularly precise measurement is required at moderate currents (e.g. balancing, revenue metering, demanding energy monitoring systems).
