Why Choose the Carlo Gavazzi CTD5S1001AXXX Split-Core Current Transformer?
The Carlo Gavazzi CTD5S1001AXXX is a compact and practical 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 fitted around an existing conductor without requiring the conductor to be disconnected.
This current transformer provides a 100 A rated primary current and 1 A secondary output, giving a 100/1 A transformation ratio for connection to compatible energy meters, power analysers and electrical monitoring equipment. The CTD5S1001AXXX is specified with Accuracy Class 3 and a rated secondary apparent power of 1.5 VA.
With a nominal 26 mm conductor opening and support for busbars up to 26 mm wide, the CTD5S1001AXXX provides a convenient solution for retrofit installations in switchboards, distribution panels and control cabinets. The split-core design is particularly valuable where existing electrical wiring needs to remain substantially undisturbed during installation.

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 electrical loads without carrying the full primary circuit current through the measuring device.
The split-core construction of the CTD5S1001AXXX makes it especially useful for retrofit projects. The core can be opened and positioned around an existing conductor, reducing the need to dismantle established wiring and helping simplify the addition of energy monitoring to existing electrical distribution systems.
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.
