Technical notes

Important notes:

Static shield winding means there is additional shielding between primary and secondary sides.
For versions with increased climate resistance, the transformer is supplied with a specially insulated finish.The finish enables the transformer to be used in areas of high humidity.

Transformer version with reinforced insulation upon request.

  • UL/CSA only up to 600 V (incl. tapping)
  • CUR according to UL-File XPTQ2.E168819 up to 4,0 kVA (Transformers, General Purpose – Component bzw. Transformers, General Purpose Certified for Canada – Component)
  • CUR according to EIS 130 or EIS 155 to OBJY2. or OBJY8.E160829 (Systems, Electrical Insulation – Component bzw. Systems, Electrical Insulation Certified for Canada – Component)

When ordering, the following information must be added to the type designation:

  • ET0,03(*/*)
  • 1st place holder ≙ rated input voltage
  • 2nd place holder ≙ rated output voltage
