The Carlo Gavazzi CTA6X600A5A is a split-core current transformer from the CTA series, designed for AC current measurement in energy metering, power monitoring and electrical control applications. Its split-core construction allows the transformer to be fitted around an existing conductor without disconnecting the primary cable, making it particularly convenient for retrofit installations.
Designed for a 600 A primary current, the CTA6X600A5A provides a standard 5 A secondary output, giving a nominal current ratio of 600:5. It provides Class 1 accuracy with a rated output of 10 VA, supporting reliable integration with compatible energy meters, power analysers and other measuring equipment using 5 A current-transformer inputs.
The transformer features a 36 mm conductor opening, a 50–60 Hz frequency range and fixed 1 m wire leads. These characteristics make the CTA6X600A5A a practical current-measurement solution for industrial and commercial electrical distribution systems where fast installation and dependable measurement are required.
A split-core current transformer measures alternating current by surrounding the primary conductor and producing a proportional secondary current for compatible measuring equipment. Because the CTA6X600A5A can be opened and positioned around an existing cable, it is especially useful when adding energy monitoring to established switchboards and electrical installations without removing the monitored conductor.
With a 600 A primary rating and 5 A secondary output, the CTA6X600A5A interfaces with compatible meters and power-monitoring equipment designed for conventional 5 A CT inputs. Its Class 1 accuracy, 10 VA output and 36 mm opening make it well suited to dependable current measurement across industrial and commercial electrical distribution systems.
