Split-core current transformers
Fig. 7: SCT6xxx
The separable measuring system of the SCT6xxx split-core current transformers enables flexible retrofitting
without disconnecting the primary conductor. Due to the minimal installation effort, they are suitable for use
in places that are difficult to access or where space is limited. Four sizes are available. Accuracy class 3 is
suitable for primary currents from 60 to 150 A, accuracy class 1 for 200 to 1000 A.
