Why Choose the Carlo Gavazzi CTD8S10005AXXX CTD-8S Current Transformer?
The Carlo Gavazzi CTD8S10005AXXX is a high-capacity split-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-8S current transformer series, it converts high primary currents into a standard secondary current suitable for compatible energy meters, power analysers and electrical monitoring equipment.
This current transformer features a 1000 A rated primary current and 5 A secondary output, providing a 1000/5 A transformation ratio. Its accuracy class 1 and 10 VA rated secondary apparent power make it suitable for dependable industrial current measurement and energy monitoring applications.
The CTD8S10005AXXX uses a practical split-core construction, allowing the transformer to be opened and fitted around an existing cable or busbar without disconnecting the primary conductor. It accommodates busbars up to approximately 30 × 80 mm, with an approximately 81 × 31 mm rectangular opening, making it particularly useful for retrofit installations in switchboards and distribution panels.
Key Advantages
Split-core 1000/5 A current transformer for high-current AC measurement.
1000 A rated primary current for substantial industrial electrical loads.
5 A secondary output compatible with suitable energy meters and power analysers.
Accuracy class 1 for dependable electrical measurement and monitoring.
10 VA rated secondary apparent power for compatible measurement circuits.
Split-core design enables installation around existing conductors without disconnecting the primary circuit.
Accommodates busbars up to approximately 30 × 80 mm.
Approximately 81 × 31 mm rectangular opening for large cables and busbars.

81 × 31 mm rectangular conductor opening.
31 mm opening height.
Split-core construction for retrofit and existing installations.
Double set of screw-terminal secondary connections.
Designed for electrical energy measurement and power monitoring systems.
Flexible Current Measurement for Existing Electrical Installations
Current transformers such as the Carlo Gavazzi CTD8S10005AXXX allow high AC currents to be measured 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 split-core construction is particularly valuable in retrofit projects because the CT can be opened and installed around an existing conductor without removing or disconnecting the cable or busbar. Combined with its 1000 A primary rating, class 1 accuracy and large rectangular opening, this makes the CTD8S10005AXXX well suited to industrial switchboards, distribution systems and energy monitoring installations.
Typical Applications
Electrical energy metering and monitoring systems.
Industrial switchboards and distribution panels.
Retrofit energy monitoring installations.
Power analysers and multifunction electrical meters.
Building energy management systems.
