Why Choose the Carlo Gavazzi CTD9S16005AXXX Current Transformer?
The Carlo Gavazzi CTD9S16005AXXX is a high-current split-core AC current transformer (CT) designed for electrical measurement, energy monitoring and power distribution applications. As part of the Carlo Gavazzi CTD9S current transformer series, it converts a rated primary current of 1600 A into a standard 5 A secondary output for connection to compatible energy meters, power analysers and monitoring equipment.
The split-core construction allows the transformer to be opened and installed around an existing conductor or busbar without removing the primary conductor. This makes the CTD9S16005AXXX particularly suitable for retrofit energy-monitoring projects, switchboard upgrades and industrial installations where disconnecting large power conductors would be inconvenient or time-consuming.
With a 1600 A primary current rating, 5 A secondary output and accuracy class 1, the CTD9S16005AXXX provides dependable current measurement for demanding industrial applications. Its large rectangular opening of approximately 126 × 36 mm accommodates busbars up to approximately 125 × 35 mm, making it well suited to high-current distribution systems and large electrical switchboards.

Flexible Current Measurement for Industrial Installations
Current transformers such as the Carlo Gavazzi CTD9S16005AXXX proportionally reduce high primary currents to a standard secondary current that can be measured by compatible instrumentation. With a 1600/5 A ratio, a 1600 A primary current corresponds to a 5 A secondary current, allowing meters and monitoring equipment to measure high-current circuits without carrying the full primary load current.
The CTD9S series combines high-current measurement capability with the installation convenience of a split-core design. Because the core can be opened and fitted around an existing conductor or busbar, the CTD9S16005AXXX is particularly suitable for retrofit energy monitoring, electrical distribution upgrades and industrial installations where removing existing conductors would be impractical.
Typical Applications
- Industrial electrical switchboards and distribution panels.
- Retrofit energy monitoring installations.
- Energy meters and power monitoring systems.
- Building energy management systems.
- Industrial machinery and automation panels.
- Electrical load and consumption monitoring.
- Power quality and electrical measurement equipment.
- Commercial and industrial busbar installations.
