£84.25
The Carlo Gavazzi CTD4X7505AXXX is a high-quality solid-core current transformer designed for accurate current measurement in industrial electrical distribution, energy monitoring and metering applications. As part of the Carlo Gavazzi CTD-4X current transformer series, it provides a dependable method of converting high primary currents into a standard secondary signal for compatible meters, power analysers and monitoring equipment.
This current transformer has a 750 A rated primary current and 5 A secondary output, providing a 750/5 A transformation ratio. Its Class 0.5 accuracy and 13 VA rated burden at Class 0.5 make it particularly suitable for applications requiring reliable measurement of substantial electrical loads.
The CTD4X7505AXXX features a generous 51 mm conductor aperture and accommodates busbars up to 64 mm wide, allowing it to be integrated around large conductors in switchboards, distribution panels and industrial electrical systems. Its solid-core construction and screw-terminal connections provide a secure solution for permanent electrical installations.
Current transformers such as the Carlo Gavazzi CTD-4X convert high primary currents into a lower proportional secondary current that can be safely measured by compatible instrumentation. This enables energy meters, power analysers and monitoring systems to measure substantial electrical loads without routing the full circuit current directly through the measuring device.
The CTD4X7505AXXX is designed for installations requiring a 750/5 A measurement ratio. Its Class 0.5 accuracy, 13 VA burden capability and large conductor opening make it a practical choice for industrial switchboards, electrical distribution systems and energy-management applications.
