The Carlo Gavazzi CTD4X5005AXXX is a robust solid-core AC current transformer designed for accurate current measurement in industrial energy metering, power monitoring and electrical distribution applications. As part of the Carlo Gavazzi CTD-4X Series, it converts a rated primary current of 500 A AC into a standard 5 A secondary output for connection to compatible energy meters, power analysers and measurement equipment.
With a transformation ratio of 500/5 A, the CTD4X5005AXXX enables high-current electrical circuits to be monitored using instrumentation equipped with standard 5 A current inputs. Its Accuracy Class 0.5 provides dependable measurement performance for industrial energy management, load monitoring and electrical metering systems.
The CTD4X5005AXXX features a large 51 mm conductor aperture and accommodates busbars up to 64 mm wide. Its stepped opening is suitable for substantial cables and busbars, while the solid-core construction, screw terminal connections and mounting flexibility make it a practical choice for permanent installations in switchboards, distribution panels and industrial electrical systems.
Current transformers such as the Carlo Gavazzi CTD4X5005AXXX allow high AC currents to be measured by transforming the primary current into a proportional secondary current that can be safely handled by standard electrical instrumentation. At its rated primary current of 500 A, the CTD4X5005AXXX provides a 5 A secondary output for compatible energy meters, power analysers and monitoring equipment.
The CTD-4X solid-core design is particularly suited to permanent installations in switchboards, distribution panels and industrial electrical systems. Its Class 0.5 accuracy, large conductor opening and support for substantial cables and busbars make the CTD4X5005AXXX a practical solution for accurate energy measurement, load monitoring and electrical power management.
