Frequently asked questions
What is a split-core current transformer?
A split-core CT opens and closes around the cable or busbar, so the primary conductor does not have to be disconnected. That makes it the first choice for retrofits in existing installations and for metering upgrades during operation (observe the safety rules for live parts). Split-core CTs explained →
What does 60/5 A mean?
With 60 A in the primary conductor, the transformer delivers 5 A to the meter or measuring device – a ratio of 12:1. Meters and instruments are set to this CT ratio.
Will it fit my cable?
The window decides: the types listed here take round conductors of Ø 40 mm, depending on the type. The datasheet of each type gives the exact window and busbar dimensions. CT finder →
Which accuracy class?
For split-core current transformers 60/5 A, class 3 is available here. Billing-relevant metering requires class 0.5 or better; for display and monitoring class 1 is usually sufficient. Accuracy class comparison →
