CTD9H6005AXXX – 600 A Primary current, 5A output 125×35 mm

Why Choose the Carlo Gavazzi CTD9H6005AXXX Current Transformer?

The Carlo Gavazzi CTD9H6005AXXX is a reliable solid-core current transformer (CT) designed for accurate measurement of high AC currents 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 600 A into a standard 5 A secondary output for connection to compatible meters, analysers and monitoring equipment.

This through-feed current transformer allows the monitored conductor or busbar to pass through its opening without requiring a direct electrical connection between the primary power circuit and measuring equipment. Its solid-core construction provides a dependable solution for permanent installations where accurate current measurement, electrical isolation and long-term industrial reliability are required.

With a 600 A primary current rating, 5 A secondary output and accuracy class 0.5, the CTD9H6005AXXX is well suited to precision metering and energy-management applications. Its horizontal CTD9H format accommodates busbars up to approximately 125 × 35 mm, with the series specified for a nominal opening of approximately 126 × 36 mm, making it suitable for large conductors and busbars in industrial switchboards.

Accurate Current Measurement for Electrical Monitoring

Current transformers such as the Carlo Gavazzi CTD9H6005AXXX proportionally reduce high primary currents to a standard secondary current that can be measured by compatible instrumentation. With a 600/5 A ratio, a 600 A primary current corresponds to a 5 A secondary current, allowing meters and monitoring devices 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 rectangular busbar opening and class 0.5 measurement accuracy makes the CTD9H6005AXXX 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.
