Split-core current transformer for AC current measurement
The Current transformer CG Split core, 300A/5A Ø24mm is a Carlo Gavazzi split-core current transformer designed for AC current measurement in existing electrical installations. The split-core construction allows installation around an existing conductor, making it particularly suitable for retrofit energy monitoring and sub-metering.
The transformer has a rated primary current of 300 A and provides a standard 5 A secondary output for connection to compatible energy meters, power analyzers and monitoring equipment.
300 A current measurement with split-core installation
The 24 mm conductor opening makes the transformer suitable for installation around appropriate cables in distribution boards and industrial switchboards. The opening core simplifies mechanical installation compared with conventional solid-core current transformers.
The CTA5X300A5A provides accuracy class 1, making it suitable for accurate current and energy monitoring where a 5 A CT input is required.
See the official Carlo Gavazzi CTA5X300A5A product information for detailed specifications and installation documentation.
