Description
Specifications

The CM-CT 100/5 is a current probe that allows the EM420 energy manager to measure the current indirectly: without being integrated into the circuit.
This way, it is possible to measure higher currents, which can go up to 100A with this probe.

This probe is a current transformer that has a nominal primary current of 100A and a secondary nominal current of 5A.
The load of this current transformer is 2.5VA and its precision is of class 1.

The CM-CT 100/5 will be useful with the EM420 energy manager in the following two cases:

If you need to indirectly measure the current without going through the EM420
If the current to measure exceeds the 63A allowed when going through the EM420
