To use a commercially available current transformer, use a CT with a secondary current rating of 1 A or 5 A, and a rated load of at least 1.0 VA.

Split Type Current Transformer (CT) (CE marking compliant KM-N2/N3 dedicated products *)

Model Rated primary current Rated secondary current
KM-NCT-E100A 100 A 1 A
KM-NCT-E250A 250 A
KM-NCT-E500A 500 A

* The KM-NCT-E conforms to the standards shown above ONLY when it is used with a power monitor KM-N2-FLK or KM-N3-FLK to which it is attached. Use of the KM-NCT-E without a power monitor does not conform to these standards.
Note: Select a CT cable that does not exceed the rated load of 1 VA.
