When ordering, the rated input voltage must
be added to the type designation:
DTA0,8(*)
The asterisk stands for the rated input
voltage.
Sample order
• requested type DTA0,8
• requested rated input voltage 400 V
The correct type designation reads
DTA0,8(400)
The unambiguous article number of your
configuration will be defined by trafomodern
during the offer- and order process.
1) In = rated motor current
2) Material surcharge –› page 64
3) Other specifications or taps on request
4) Design only applicable for unloaded starting
5) It is imperative that the motor consumes
only a starting current of max. 4.5 x In at
the indicated
rated output voltage.
