Split-core current transformer for AC current measurement
The Current transformer CG Split core, 150A/5A Ø24mm is a Carlo Gavazzi split-core current transformer designed for measuring AC current without disconnecting the existing conductor. The split-core construction makes it particularly suitable for retrofit energy monitoring and installations where replacing or disconnecting cables is impractical.
The transformer has a rated primary current of 150 A and provides a standard 5 A secondary output for connection to compatible energy meters, power analyzers and measuring equipment.
150 A current measurement with split-core installation
The 24 mm opening allows the transformer to be installed around an existing conductor. The hinged split-core design simplifies installation in switchboards and distribution panels while reducing the amount of electrical work required compared with conventional solid-core current transformers.
This model has accuracy class 3 and is suitable for general current measurement, load monitoring and energy management applications.
See the official Carlo Gavazzi CTA5X150A5A product information for detailed specifications and installation documentation.
