Coils Type DFD

Single or three-phase coils are indispensable components in guaranteeing the performance and safety of electrical applications. They are made by us on the basis of EN 61558-2-20, with special core assemblies and high-quality vacuum impregnation using black polyester resin. We manufacture network, commutation and reactors.



In combination with capacitors, coils can be optimally adjusted to the required system conditions, improving the network’s impedance behavior.


  • Open design (IP 00, installation max. IP 23)
  • Low noise level thanks to high-quality, tropical vacuum impregnation
  • Integrated thermal switch (NC contact 250 V / 2.5 A)
  • Coils made of copper or aluminum
  • Depending on the nominal current: screw terminals or Cu conductor rail
  • Wear-proof, heat, UV and solvent resistant type plate
  • Special versions are available upon request
