The Carlo Gavazzi CTD10V40005AXXX is a robust solid-core current transformer (CT) designed for accurate measurement of high AC currents in industrial electrical installations, power distribution systems and energy monitoring applications. As part of the Carlo Gavazzi CTD 10V series, it provides dependable current transformation for use with energy meters, power analysers and electrical monitoring equipment.
This current transformer converts a high primary current into a standardised secondary current that can be safely measured by compatible instrumentation. Its solid-core construction provides a reliable solution for permanent installations, while the large rectangular busbar opening makes it particularly suitable for high-current switchboards, distribution panels and industrial energy management systems.
With a rated primary current of 4000 A and a 5 A secondary output, the CTD10V40005AXXX provides a transformation ratio of 4000/5 A. The CTD 10V design supports Class 0.5, Class 1 and Class 3 measurement, operates across 48–62 Hz and accommodates busbars up to approximately 126 × 51 mm, making it well suited to high-current industrial monitoring applications.
Current transformers such as the Carlo Gavazzi CTD10V40005AXXX enable very high AC currents to be measured without routing the full primary current through the connected measuring instrument. The transformer produces a proportional 5 A secondary current that can be used by compatible energy meters, power analysers and electrical monitoring equipment.
The CTD 10V series is designed for high-current applications where accurate measurement, a substantial busbar opening and robust construction are essential. Its 4000/5 A transformation ratio, multiple accuracy classes and solid-core design make the CTD10V40005AXXX particularly suitable for permanent industrial power distribution, energy management and electrical monitoring installations.
