Why Choose the Carlo Gavazzi CTA6X500A5A Current Sensor?
The Carlo Gavazzi CTA6X500A5A is a split-core current transformer from the CTA series, designed for accurate AC current measurement in energy monitoring, metering and electrical control applications. Its split-core construction allows the transformer to be installed around an existing conductor without disconnecting the primary cable, making it particularly useful for retrofit installations.
Designed for a 500 A primary current, the CTA6X500A5A provides a standard 5 A secondary output, giving a nominal current ratio of 500:5. It offers Class 1 accuracy and a rated output of 7.5 VA, making it suitable for use with compatible energy meters and current-measurement equipment with 5 A current inputs.
A 36 mm conductor opening accommodates substantial cables while the 50–60 Hz operating frequency suits standard AC power-distribution systems. The combination of split-core installation, standardised 5 A output and compact construction makes the CTA6X500A5A a practical choice for new and existing electrical installations.

Convenient Split-Core Current Measurement for Energy Monitoring
A split-core current transformer measures AC current by surrounding the primary conductor and producing a proportional secondary current for compatible measurement equipment. Unlike a solid-core transformer, the CTA6X500A5A can be opened and fitted around an existing conductor, significantly simplifying installation during electrical-system upgrades and energy-monitoring retrofits.
With a 500 A primary rating and 5 A secondary output, the CTA6X500A5A can interface with compatible energy meters and monitoring equipment designed for conventional 5 A current-transformer inputs. Its Class 1 accuracy, 7.5 VA output and 36 mm opening make it suitable for dependable current measurement in industrial and commercial electrical distribution systems.
Typical Applications
- Industrial energy monitoring systems.
- Electrical power and energy metering.
- Retrofit current-measurement installations.
- Distribution boards and electrical switchboards.
- Building energy-management systems.
- Industrial control and automation panels.
- Load monitoring on high-current AC circuits.
- Energy meters requiring external 5 A current-transformer inputs.
