Characteristics

General data

The control transformers of the TT1 series ensure safe galvanic isolation of the primary circuit from the secondary circuit. The unique BLOCK IMPEX vacuum impregnation process provides excellent protection against external influences while reducing noise levels. The transformers stand out with a wide range of mounting options and integrated crane eyelets for transport and installation.

Benefits

› Control and safety isolating transformer according to EN (IEC) 61558-2-2 and EN (IEC) 61558-2-6

› Patented mounting technology

› Primary side ±5% taps for voltage adjustment

› Fixed, touch-protected screw terminals according to UVV BGV A3

› Space-saving due to upright design
