The Carlo Gavazzi CTD8H15005AXXX is a high-capacity 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 high primary currents into a standard secondary current suitable for compatible energy meters, power analysers and monitoring equipment.
This current transformer features a 1500 A rated primary current and 5 A secondary output, providing a 1500/5 A transformation ratio. With accuracy class 0.5 and a rated burden of 15 VA at class 0.5, the CTD8H15005AXXX is well suited to demanding electrical metering and monitoring applications where reliable current measurement is required.
The CTD8H15005AXXX is designed for large conductors and busbars, with a rectangular opening suitable for busbars up to approximately 80 × 30 mm. The manufacturer specifies a 31 mm aperture height and maximum busbar width of 81 mm. Its horizontal CTD 8H configuration and screw-terminal secondary connections make it suitable for integration into switchboards, distribution panels and industrial electrical installations.
Current transformers such as the Carlo Gavazzi CTD8H15005AXXX allow high AC currents to be measured 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 busbars and high primary currents need to be monitored. Its solid-core construction, class 0.5 measurement accuracy, large rectangular aperture and standard 5 A secondary output make the CTD8H15005AXXX particularly suitable for switchboards, main distribution panels and energy monitoring installations requiring a 1500 A current transformer.
