Carlo Gavazzi CTD8H8005AXXX CTD-8H solid-core current transformer with an 800 A primary rating, 5 A secondary output, class 0.5 accuracy, 8 VA rated secondary apparent power and 80 x 30 mm nominal horizontal busbar capacity for industrial electrical metering and monitoring applications.
£119.90
The Carlo Gavazzi CTD8H8005AXXX is a robust solid-core current transformer (CT) designed for accurate 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 electrical monitoring equipment.
This current transformer features a 800 A rated primary current and 5 A secondary output, providing an 800/5 A transformation ratio. Its accuracy class 0.5 and 8 VA rated secondary apparent power make it suitable for dependable electrical metering and monitoring applications where accurate measurement of substantial industrial loads is required.
The CTD8H8005AXXX is designed for large cables and busbars, with a nominal 80 × 30 mm horizontal busbar capacity. Its rectangular conductor opening measures approximately 81 × 31 mm, while the horizontal solid-core configuration and screw-terminal secondary connections make it suitable for installation in switchboards, distribution panels and industrial electrical systems.
Current transformers such as the Carlo Gavazzi CTD8H8005AXXX 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 substantial cables or busbars need to be accommodated. Its solid-core construction, class 0.5 measurement accuracy, standard 5 A secondary output and large rectangular conductor opening make the CTD8H8005AXXX particularly suitable for switchboards, distribution panels and energy monitoring systems requiring an 800 A primary current transformer.
