Article features
- This clip-on current transformer is mostly used for new installations, as the circuit must be interrupted here.
- Most cost-effective and most common variant
- Simply plug the transformer onto the primary conductor (no need for complex wiring)
- Currently the most compact design on the market, thus wonderfully suitable for the control cabinet
- Other areas of application are machine and plant construction.
¤ Special designs on request:
- any primary and secondary rated currents
- operating voltage series 1 (1,2kV)
- Cast resin grouting
