Product information

The plug-on current transformer ASK 31.5 2U is a compact, high-precision low-voltage measuring transformer of the proven AS series that can be switched between two primary currents, specially developed for use in power distribution, switchgear, meter panels and industrial measurement and monitoring systems.

Technical main features:
  • Type plug-on current transformer – ASK 31.5 2U
  • Primary conductor bore For round conductors and busbars (typically up to approx. Ø 21 mm or 30 × 10 mm)
  • Maximum operating voltage Um ≤ 0.72 kV
  • Rated frequency 50–60 Hz
  • Insulation class E
  • Insulation test voltage 3 kV, 50 Hz, 1 min
  • Mounting Plug-on mounting on primary conductor, optionally with mounting foot

The plug-on current transformer ASK 31.5 2U is characterized by its very compact design, easy mounting and high reliability – ideal for subsequent measurements and retrofit applications in existing systems.

We are happy to supply this model at short notice from stock or configure further variants of the ASK series for you.
