Dreiphasige Sicherheitstransformatoren ET3o ** mit einer Leistung von 0,05 bis 16 kVA
Three-phase safety isolating transformers are assigned for supplying electric devices with safe voltage. In standard design, the transformers are adjusted to fastening by means of screwed angles. The windings terminals may be placed on one side only, or on both sides of a transformer. Upon request, the transformers may be assembled in enclosures with the protection degree of IP 23, IP 44 and IP 54.
ELHAND Transformatory reserves the right to introduce changes resulting from the continuous development of the offered products. It is possible to make a transformer in a different version after prior agreement.

*) - for transformer design with climatic/environmental class C2/E1 (maritime design W/3 or tropical design T/3) the letter "M" or "G" ought to be added depending on final application
**) - this table was prepared basing on the technical specification for transformer with voltage ratio 400//24 operating under normal conditions. For other conditions and data the values may change
Note:
Manufacturer reserves the right to make changes resulting from the continuous development of products offered.
If requested in advance, it is possible to manufacture transformer in other version.
