Isolating transformer, three-phase

TT3-A630-4040-0

Characteristics

Benefits

 Safe galvanic isolation

 Very good corrosion protection and low noise thanks to BLOCK IMPEX vacuum impregnation

 Very good discharging of thermal losses by means of optimally arranged cooling channels within the coils

 Integrated crane eyes

 If desired, the transformers can be realised in individual voltages
