Why Choose the Carlo Gavazzi CTD8H2005AXXX CTD-8H Current Transformer?
The Carlo Gavazzi CTD8H2005AXXX is a solid-core current transformer (CT) designed for AC current measurement in electrical distribution, energy monitoring and industrial power management applications. As part of the Carlo Gavazzi CTD-8H current transformer series, it converts the current flowing through a primary conductor into a standard secondary current suitable for compatible energy meters, power analysers and monitoring equipment.
This current transformer features a 200 A rated primary current and 5 A secondary output, providing a 200/5 A transformation ratio. Its accuracy class 3 and 4 VA rated secondary burden make it suitable for general industrial current measurement and monitoring applications where a standard 5 A secondary signal is required.
The CTD8H2005AXXX is designed for cables and large busbars, with a nominal 80 × 30 mm busbar capacity. Its opening provides approximately 31 mm height and 81 mm maximum busbar width, while the horizontal solid-core configuration and screw-terminal secondary connections make it suitable for installation in switchboards, distribution panels and industrial electrical systems.

Reliable Current Measurement for Electrical Monitoring
Current transformers such as the Carlo Gavazzi CTD8H2005AXXX allow AC current to be monitored by converting the current flowing through the primary conductor into a proportional lower secondary current. The resulting 5 A signal can be connected to compatible energy meters, multifunction meters, power analysers and electrical monitoring equipment without requiring the full primary current to pass directly through the measuring instrument.
The CTD-8H series is designed for industrial electrical distribution systems where cables or substantial busbars need to be accommodated. Its solid-core construction, standard 5 A secondary output, large rectangular conductor opening and horizontal configuration make the CTD8H2005AXXX particularly suitable for switchboards, distribution panels and monitoring systems requiring a 200 A primary current transformer.
Typical Applications
- Electrical current and energy monitoring systems.
- Industrial switchboards and distribution panels.
- Power analysers and multifunction electrical meters.
- Building energy management systems.
- Industrial automation and control panels.
- Busbar current and electrical load monitoring.
