  • Space-saving installation with compact design and consistent 30 mm housing width
  • Extra safety: safe isolation according to EN 50178 up to 1000 V
  • Detect peak loads reliably with a thermal nominal continuous current that is 120-percent of the primary rated current
  • Safe wiring, thanks to innovative connection technology

Saves space and time – current transformer quick-action mechanism


The quick-action mechanism allows PACT current transformers to be installed quickly and securely on the power rail.  The transformers can also be mounted by hand in areas where a screwdriver does not fit.
