Why Choose the Carlo Gavazzi CTA6X300A5A Current Transformer?

The Carlo Gavazzi CTA6X300A5A is a split-core current transformer designed for accurate AC current measurement in energy metering and electrical monitoring applications. Part of the Carlo Gavazzi CTA series, its split-core construction allows installation around an existing conductor without disconnecting the primary cable, making it particularly well suited to retrofit installations.

The CTA6X300A5A has a rated primary current of 300 A and provides a standard 5 A secondary output, giving a current transformation ratio of 300:5. Its Class 1 accuracy and 50/60 Hz operating frequency make it suitable for connection to compatible energy meters, power monitoring instruments and measurement systems with 5 A current inputs.

A generous 36 mm conductor opening accommodates larger primary conductors, while the integrated 1 m secondary cable simplifies connection to associated measuring equipment. The CTA6X300A5A provides a practical combination of accurate measurement, rapid installation and retrofit flexibility for commercial and industrial electrical systems.

Flexible Current Measurement for Energy Monitoring

Split-core current transformers provide a convenient method of measuring higher AC currents without routing the full primary current through the connected measuring instrument. The transformer produces a proportional secondary current that can be measured by compatible energy meters, power analysers and monitoring equipment, providing safe and practical current measurement within electrical installations.

The Carlo Gavazzi CTA6X300A5A is particularly useful for retrofit projects because its split-core design can be opened and fitted around an existing conductor. With its 300:5 ratio, Class 1 accuracy and standard 5 A secondary output, it can be paired with compatible Carlo Gavazzi and third-party measuring equipment designed for 5 A current transformer inputs.

Typical Applications

  • Industrial electrical energy monitoring.
  • Commercial building energy metering.
  • Electrical distribution panel monitoring.
  • Power and energy management systems.
  • Retrofit current measurement installations.
  • Energy meters and power analysers with 5 A CT inputs.
