Designed and tested according

  • IEC/EN 61558-2-1
  • EN 60076-11
  • UL 5085-2
  • CSA 22.2 No. 66

Typical applications

  • Voltage adjustment

Basic equipment

  • Separate windings
  • Insulation class B / F from 6.3 kVA
  • Ambient temperature 25 to 40 C
  • Connection terminal (<=115 A)
  • Frequency 50/60 Hz

CAD data

  • 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/CSAonly 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

Sample order

  • requested typeET0,03
  • requested rated input voltage 230 V
  • requested rated output voltage 12 V

The correct type designation reads ET0,03(230/12)

The unambiguous article number of your configuration will be defined by trafomodern during the offer- and process.
