The Carlo Gavazzi CTD10V20005AXXX is a robust and accurate solid-core current transformer (CT) designed for measuring high AC currents in industrial electrical installations, power distribution systems and energy monitoring applications. As part of the Carlo Gavazzi CTD 10V series, it is specifically designed for vertical busbar mounting and provides dependable current transformation for metering and monitoring equipment.
This current transformer converts a high primary current into a standardised secondary current that can be safely measured by compatible energy meters, power analysers and monitoring devices. Its solid-core construction, busbar mounting facility and screw-terminal connections provide a practical solution for permanent installations in electrical switchboards and industrial control systems.
With a rated primary current of 2000 A and a 5 A secondary output, the CTD10V20005AXXX provides a transformation ratio of 2000/5 A. It offers Class 0.5 accuracy, a rated secondary burden of 25 VA at Class 0.5 and accommodates busbars up to 50 × 125 mm, making it ideal for accurate high-current measurement in demanding industrial installations.
Current transformers such as the Carlo Gavazzi CTD10V20005AXXX enable high AC currents to be accurately monitored 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 electrical monitoring equipment.
The CTD 10V series is designed for high-current busbar applications where dependable measurement, straightforward installation and robust construction are essential. Its 2000/5 A transformation ratio, Class 0.5 accuracy and solid-core construction make the CTD10V20005AXXX particularly suitable for permanent industrial power distribution and energy management installations.
