Description
1. - This clip-on current transformer is mostly used for new installations, as the circuit must be interrupted here.
2. - Short-circuiting of the current transformer when the secondary terminal cover is open.
3. - More economical cable routing and lower power loss due to elimination of the transformer disconnect termainal.
4. - Easy handling facilitated by a rotatable and sealable secondary terminal cover.
5. - Suitable for both floor and side mounting.
6. - Most cost-effective and most common variant
7. - Simply plug the transformer onto the primary conductor (no need for complex wiring)
8. - Currently the most compact design on the market, thus wonderfully suitable for the control cabinet
9. - Other areas of application are machine and plant construction.
