Why Choose the Carlo Gavazzi CTA6X200A5A Current Sensor?
The Carlo Gavazzi CTA6X200A5A is a split-core current transformer from the CTA series, designed for AC current measurement in energy metering, monitoring and electrical distribution applications. It has a rated primary current of 200 A and provides a standard 5 A secondary output, giving a transformation ratio of 200:5 for use with compatible energy meters and measuring instruments.
Its split-core construction enables the transformer to be opened and installed around an existing conductor without disconnecting the power cable. This makes the CTA6X200A5A particularly suitable for retrofit energy-monitoring projects where minimising installation work and electrical disruption is important.
The CTA6X200A5A features a large 36 mm conductor aperture, Class 3 accuracy and a 1 VA burden. Designed for 50–60 Hz AC systems and supplied with a 1 m secondary cable, it provides a practical current measurement solution for commercial and industrial electrical installations.
Key Advantages
- Split-core design enables installation around existing electrical conductors.
- 200 A primary current rating for industrial and commercial measurement applications.
- Standard 5 A secondary output for compatible meters and monitoring equipment.
- 200:5 transformation ratio for conventional current transformer measurement systems.
- 36 mm aperture accommodates larger conductors than smaller CTA-series models.
- Class 3 accuracy for general-purpose metering and monitoring applications.
- 1 VA burden at the specified accuracy class.
- Supplied with a 1 m secondary cable for convenient installation.

Convenient Retrofit Current Measurement
Split-core current transformers are particularly useful when adding energy monitoring to an existing electrical installation. The CTA6X200A5A can be opened and positioned around an existing conductor, avoiding the need to pass the cable through a permanently closed transformer core and helping simplify retrofit installation.
With its 200:5 transformation ratio, the CTA6X200A5A converts primary AC current into a standard 5 A secondary signal for compatible metering equipment. Its comparatively large 36 mm opening provides additional installation flexibility where larger conductors are used in switchboards, distribution panels and industrial electrical systems.
