Why Choose the Carlo Gavazzi CTD10S8005AXXX 800 A Split-Core Current Transformer?
The Carlo Gavazzi CTD10S8005AXXX is a robust split-core current transformer (CT) designed for accurate current measurement in electrical energy monitoring, metering and industrial power management applications. As part of the Carlo Gavazzi CTD10S series, it provides a practical solution for measuring high primary currents without requiring the monitored conductor or busbar to be disconnected during installation.
With a rated primary current of 800 A and a standard 5 A secondary output, the CTD10S8005AXXX provides an 800/5 A transformation ratio for connection to compatible energy meters, power analysers, transducers and current monitoring equipment. Its Class 1 accuracy makes it suitable for dependable electrical measurement across commercial and industrial installations.
The split-core construction simplifies installation around existing cables and busbars, making the CT particularly useful for retrofit energy monitoring projects and installations where interrupting the electrical conductor would be inconvenient. The CT accommodates conductors through an opening up to approximately 51 × 126 mm and provides a rated secondary apparent power of 10 VA.
Key Advantages
Split-core current transformer designed for retrofit installation.
800 A rated primary current for high-current electrical circuits.
Standard 5 A secondary output for compatible metering and monitoring equipment.
800/5 A transformation ratio for industrial current measurement.

Practical Current Measurement for Energy Monitoring
Current transformers such as the Carlo Gavazzi CTD10S8005AXXX reduce high primary currents to a standard secondary current that compatible measuring instruments can safely monitor. Its 800/5 A ratio allows an 800 A primary circuit to be represented by a proportional 5 A secondary signal for energy meters, power analysers, transducers and other electrical measurement equipment.
The split-core design is particularly valuable for retrofit projects because the CT can be fitted around an existing conductor rather than requiring the conductor to be threaded through a permanently closed core. This can simplify installation in established switchboards, distribution systems and energy monitoring projects where access or downtime is limited.
Typical Applications
Industrial energy monitoring and management systems.
Electrical switchboards and distribution panels.
Power and energy metering installations.
Retrofit electrical monitoring projects.
Building management and energy management systems.
Industrial machinery and production facilities.
