CTD1X1255AXXX

Overview

The Carlo Gavazzi CTD1X1255AXXX is a solid core industrial current transformer designed for busbar installation. It features a primary current rating of 125 A and a secondary output of 5 A, providing a 125:5 transformation ratio. The unit operates within a frequency range of 48 Hz to 62 Hz and carries an accuracy class of 0.5. Physical dimensions include a bore diameter of 23.3 mm, with overall measurements of 44 mm in length, 30 mm in width, and 65.2 mm in height. It utilizes screw termination and functions reliably between -25°C and +60°C.

Feature Summary

• Solid core construction for secure busbar mounting
• High precision measurement capability
• Standardized secondary output for metering compatibility

Applications

• Industrial power distribution monitoring
• Electrical panel energy management systems
• Current measurement for power analyzers

Procurement Notes

Verify the specific part number suffix against official Carlo Gavazzi documentation to ensure correct configuration. Confirm that the required accuracy class and physical dimensions match the installation constraints. Check regional availability as distribution status may vary by location. Ensure compatibility with existing metering or protection devices requiring a 5A secondary input.

Selection Notes

Select this model when a 125A primary current rating and 5A secondary output are required for busbar applications. The solid core design necessitates installation before cable termination. Verify that the operating frequency aligns with the system's 48-62 Hz range. Consider the physical bore size of 23.3 mm to ensure it accommodates the target conductor or busbar dimensions without modification.
