CTB – clip-on current transformer

In addition to a higher maximum operating voltage (Um < 1.2 kV), the clip-on CTB transformer also offers a higher insulation test voltage (6 kV Ueff, 1 min., 50 Hz), as well as a higher operating temperature range (-5 °C < T < +50 °C).

The transformer is equipped with a maintenance-free cage clamp technology. This makes the transformer maintenance-free. The new current transformer type is manufactured in accordance with the technical requirements specified in DIN EN 61869-1/2, VDE 0414-9-1/2 and DIN 42600.
