Product description

Article features

  1. This calibrated current transformer is suitable for billing purposes
  2. The design is approved by the Physikalisch Technische Bundesanstalt (PTB) Braunschweig
  3. This clip-on current transformer is mostly used for new installations, as the circuit must be interrupted here.
  4. Short-circuiting of the current transformer when the secondary terminal cover is open.
  5. More economical cable routing and lower power loss due to elimination of the transformer disconnect terminal.
  6. Easy handling facilitated by a rotatable and sealable secondary terminal cover.
  7. Suitable for both floor and side mounting.
  8. Most cost-effective and most common variant
  9. Simply plug the transformer onto the primary conductor (no need for complex wiring)
  10. Currently the most compact design on the market, thus wonderfully suitable for the control cabinet
  11. Other areas of application are machine and plant construction.
