CTA5X100A5A

Overview

The CTA5X100A5A is a split core industrial current sensor manufactured by Carlo Gavazzi. It features a primary current rating of 100 A and a secondary current rating of 5 A, resulting in a turns ratio of 100:5. The device operates within a frequency range of 50 Hz to 60 Hz. Designed for free hanging installation, it utilizes wire leads for termination. Physical dimensions include a height of 65.2 mm, length of 45.2 mm, and width of 34 mm. The unit supports an operating temperature range from -20°C to +65°C.

Feature Summary

• Split core design allows for non-intrusive installation around existing conductors without circuit interruption.
• Provides accurate current sensing with a standard 100:5 turns ratio for compatibility with measurement devices.
• Free hanging mounting style offers flexible integration into various electrical panel configurations.

Applications

• Industrial power monitoring systems
• Electrical distribution panels
• Energy management meters

Procurement Notes

Verify the specific part number suffix against official Carlo Gavazzi documentation to ensure correct secondary output and insulation class. Confirm that the required primary conductor diameter fits within the split core aperture before ordering. Check regional availability as distribution status may vary by location. Ensure the target application frequency matches the 50 Hz to 60 Hz specification. Review technical drawings for precise mounting clearances.

Selection Notes

Select this model when a 100 A primary current capacity is required for split core applications. Ensure the connected measuring instrument accepts a 5 A secondary input signal. Verify that the ambient temperature conditions remain within the specified -20°C to +65°C operational range. Consider the physical dimensions for adequate space allocation in the installation environment. Confirm wire lead length meets connection requirements.

Part Context

This component belongs to the CTA series of split core current transformers from Carlo Gavazzi. These sensors are engineered for industrial environments requiring reliable current measurement. The series typically includes variants with different primary current ratings while maintaining consistent secondary outputs and form factors. This specific model represents the 100 A variant within that product line.

Replacement Considerations

Consult official Carlo Gavazzi cross-reference guides for verified substitute part numbers. Generic replacements may not match the exact aperture size or accuracy class. Ensure any alternative maintains the 100:5 turns ratio and 5 A secondary output. Verify mechanical fit and terminal type compatibility before substitution.
