Why Choose the Carlo Gavazzi CTD5S1005AXXX Split-Core Current Transformer?
The Carlo Gavazzi CTD5S1005AXXX is a reliable split-core current transformer designed for electrical current measurement, energy monitoring and metering applications. As part of the Carlo Gavazzi CTD-5S current transformer series, its split-core construction allows the transformer to be opened and installed around an existing cable or busbar without disconnecting the primary conductor.
This current transformer provides a 100 A rated primary current and 5 A secondary output, giving a 100/5 A transformation ratio for connection to compatible energy meters, power analysers and electrical monitoring equipment. Its Accuracy Class 3 and 1.5 VA rated secondary apparent power provide dependable performance for industrial and commercial current-monitoring applications.
The CTD5S1005AXXX accommodates cables up to approximately 26 mm diameter and busbars up to 26 × 32 mm. Its split-core format, double screw terminals and flexible mounting arrangement make it particularly useful for retrofit installations in switchboards, distribution panels and existing electrical systems.

Convenient Current Measurement for Existing Electrical Systems
Current transformers such as the Carlo Gavazzi CTD-5S convert the current flowing through a primary conductor into a lower proportional secondary current suitable for compatible measuring instruments. This allows energy meters, power analysers and monitoring systems to measure substantial electrical loads without carrying the full primary circuit current through the measuring device.
The split-core construction of the CTD5S1005AXXX makes it especially useful for retrofit projects. The core can be opened and positioned around an existing cable or busbar, reducing the need to dismantle established wiring while its 100/5 A ratio provides a standard 5 A signal for compatible industrial metering equipment.
Typical Applications
- Retrofit energy metering installations.
- Electrical switchboards and distribution panels.
- Power analysers and multifunction electrical meters.
- Building energy management systems.
- Industrial machinery and control cabinets.
- Electrical load and consumption monitoring.
