Carlo Gavazzi CTD8H1505AXXX CTD-8H solid-core current transformer with a 150 A primary rating, 5 A secondary output, class 3 accuracy and capacity for busbars up to approximately 80 x 30 mm for industrial electrical current monitoring applications.
£113.63
The Carlo Gavazzi CTD8H1505AXXX is a compact and dependable solid-core current transformer (CT) designed for 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 current flowing through a primary conductor into a standard secondary current suitable for compatible energy meters, power analysers and monitoring equipment.
This current transformer features a 150 A rated primary current and 5 A secondary output, providing a 150/5 A transformation ratio. Its accuracy class 3 and 2 VA rated secondary apparent power make it suitable for general-purpose industrial current monitoring applications where a standard 5 A secondary measurement signal is required.
The CTD8H1505AXXX is designed for larger conductors and busbars, with a nominal 80 × 30 mm busbar capacity. The transformer has a 31 mm hole diameter and accommodates busbars up to approximately 81 mm wide. Its 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 CTD8H1505AXXX 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, standard 5 A secondary output, large rectangular conductor opening and horizontal mounting arrangement make the CTD8H1505AXXX particularly suitable for switchboards, control panels and monitoring systems requiring a 150 A primary current transformer.
