  • Differential current transformer type A, series DACT

  • for detection of residual currents in 3- / 4-phase AC systems
  • Current transformers

  • Differential current transformers type A of the series “DACT“ are designed to detect even smallest residual currents. Together with evaluation units they are used for monitoring and protection of electrical circuits.

    There are four different sizes available for a wide range of conductor cross-sections, i.e. currents.
