Current transformer CTB
- With UL Certification
- Current transformers
This latest current transformer type CTB incorporates not only a higher maximum operating voltage (Um < 1,2 kV) but also an increased insulation test voltage (6 kV Ueff, 1 min, 50 Hz) as well as an increased ambient temperature range (-5 °C < T < +50 °C).
The new CTB’s connection is arranged with a "cage clamp ®".
The production of the new current transformer is in accordance with the technical characteristics corresponding to IEC 61869-1/2.
