Isolating transformer, three-phase
TT3-A010-4040-0
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
