CTD9H7005AXXX – 700 A Primary current, 5A output 125×35 mm

Why Choose the Carlo Gavazzi CTD9H7005AXXX Current Transformer?

The Carlo Gavazzi CTD9H7005AXXX is a solid-core AC current transformer (CT) designed for accurate current measurement in industrial electrical installations, energy monitoring systems and distribution panels. As part of the Carlo Gavazzi CTD9H current transformer series, it converts a rated primary current of 700 A into a standard 5 A secondary output for connection to compatible meters, analysers and monitoring equipment.

This through-feed current transformer provides a practical method of measuring high AC currents while maintaining electrical isolation between the primary conductor and the measurement circuit. Its solid-core construction is particularly suited to permanent installations, while its horizontal format allows integration around large busbars in industrial switchboards and power distribution equipment.

With a 700 A primary current rating, 5 A secondary output and accuracy class 0.5, the CTD9H7005AXXX is suitable for precision metering and energy-management applications. The CTD9H format accommodates busbars up to approximately 125 × 35 mm, while the series also provides a 36 mm circular opening for compatible conductors.

Accurate Current Measurement for Electrical Monitoring

Current transformers such as the Carlo Gavazzi CTD9H7005AXXX proportionally reduce high primary currents to a standard secondary current that can be measured by compatible instrumentation. With a 700/5 A ratio, a 700 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 CTD9H series is designed for industrial switchboards, distribution systems and energy-monitoring installations where dependable current measurement is essential. Its combination of solid-core construction, large busbar capacity and class 0.5 measurement accuracy makes the CTD9H7005AXXX particularly suitable for permanent installations requiring precise monitoring of electrical loads.

Typical Applications

• Industrial electrical switchboards and distribution panels.
• 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.
