Why Choose the Carlo Gavazzi CTD9S10005AXXX Current Transformer?
The Carlo Gavazzi CTD9S10005AXXX is a high-quality split-core current transformer (CT) designed for accurate measurement of high AC currents in industrial electrical installations, energy monitoring systems and distribution panels. As part of the Carlo Gavazzi CTD9S current transformer series, it converts a rated primary current of 1000 A into a standard 5 A secondary output for connection to compatible meters, power analysers and monitoring equipment.
The split-core construction allows the transformer to be installed around an existing conductor or busbar without disconnecting or removing the primary conductor. This makes the CTD9S10005AXXX particularly useful for retrofit energy-monitoring projects, switchboard upgrades and installations where interruption of the existing electrical circuit needs to be minimised.
With a 1000 A primary current rating, 5 A secondary output and accuracy class 1, the CTD9S10005AXXX provides dependable current measurement for industrial applications. Its large rectangular opening of approximately 126 × 36 mm accommodates busbars up to approximately 125 × 35 mm, making it suitable for high-current distribution systems and large industrial switchboards.

Flexible Current Measurement for Industrial Installations
Current transformers such as the Carlo Gavazzi CTD9S10005AXXX proportionally reduce high primary currents to a standard secondary current that can be measured by compatible instrumentation. With a 1000/5 A ratio, a 1000 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 CTD9S10005AXXX 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.
