CTD3X4005AXXX

Overview

The Carlo Gavazzi CTD3X4005AXXX is a solid core industrial current transformer designed for busbar installation. It features a primary current rating of 400 A and a secondary output of 5 A, providing a standard transformation ratio for measurement applications. The unit operates within a frequency range of 48 Hz to 62 Hz and supports screw termination for secure electrical connections. Physically, the device measures 109 mm in height, 77 mm in length, and 42 mm in width. It functions reliably within an ambient temperature range from -25 °C to +60 °C.

Feature Summary

• Solid core construction optimized for direct busbar mounting
• Standard 400:5 A transformation ratio for industrial metering
• Screw terminal interface for reliable circuit connection

Applications

• Industrial power distribution monitoring
• Electrical panel current measurement
• Energy management system integration

Procurement Notes

Verify the specific revision status when ordering, as documentation references version 17. Confirm that the physical dimensions align with available panel space, noting the 109 mm height constraint. Ensure the busbar size accommodates the internal aperture. Cross-reference the frequency requirements against the operational grid standards to confirm compatibility with the specified 48-62 Hz range before finalizing procurement.

Selection Notes

Select this model when a 400 A primary rating is required for solid-core busbar applications. The CTD3X series offers a compact footprint compared to larger industrial alternatives. Consider the operating temperature limits if the installation environment exceeds standard indoor conditions. Verify that the 5 A secondary output matches the input specifications of the connected measuring instruments or relays.

Part Context

This component belongs to the CTD3X series of current transformers manufactured by Carlo Gavazzi. The series is characterized by solid core designs intended for high-current industrial environments. The CTD3X4005AXXX specifically addresses the need for precise current monitoring at the 400 A level, fitting into the broader portfolio of measurement devices used in power quality and distribution analysis.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. When evaluating alternatives, ensure the replacement maintains the 400:5 A ratio, solid core topology, and compatible busbar dimensions.
