Carlo Gavazzi CTD8H20005AXXX CTD-8H solid-core current transformer with a 2000 A primary rating, 5 A secondary output, class 0.5 accuracy and 80 x 30 mm nominal busbar capacity for industrial electrical metering and monitoring applications.
£131.51
The Carlo Gavazzi CTD8H20005AXXX 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 electrical monitoring equipment.
This current transformer features a 2000 A rated primary current and 5 A secondary output, providing a 2000/5 A transformation ratio. Its accuracy class 0.5 and 20 VA rated burden at class 0.5 make it particularly suitable for demanding electrical metering and monitoring applications where reliable measurement of high currents is required.
The CTD8H20005AXXX is designed for large conductors and busbars, with a nominal 80 × 30 mm busbar capacity and an approximately 81 × 31 mm rectangular aperture. Its horizontal CTD-8H configuration, solid-core construction and screw-terminal secondary connections make it well suited to main switchboards, distribution panels and industrial electrical installations.
Current transformers such as the Carlo Gavazzi CTD8H20005AXXX 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 CTD8H20005AXXX particularly suitable for main switchboards, distribution panels and energy monitoring installations requiring measurement of currents up to 2000 A.
