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.
| 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.
