Carlo Gavazzi CTD8H7005AXXX CTD-8H solid-core current transformer with a 700 A primary rating, 5 A secondary output, class 0.5 accuracy at 6 VA and 80 x 30 mm nominal horizontal busbar capacity for industrial electrical metering and monitoring applications.
£118.94
The Carlo Gavazzi CTD8H7005AXXX 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 700 A rated primary current and 5 A secondary output, providing a 700/5 A transformation ratio. It provides accuracy class 0.5 at a 6 VA burden, with higher permissible burdens of 10 VA at class 1 and 12 VA at class 3, making it suitable for dependable industrial metering and current monitoring applications.
The CTD8H7005AXXX is designed for large cables and busbars, with a nominal 80 × 30 mm horizontal busbar capacity. Its conductor opening is approximately 81 × 31 mm, while the horizontal solid-core configuration and screw-terminal secondary connection make it suitable for installation in switchboards, distribution panels and industrial electrical systems.
Current transformers such as the Carlo Gavazzi CTD8H7005AXXX 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 capability, standard 5 A secondary output and large rectangular conductor opening make the CTD8H7005AXXX particularly suitable for switchboards, distribution panels and energy monitoring systems requiring a 700 A primary current transformer.
