CTA6X400A5A

Overview

The Carlo Gavazzi CTA6X400A5A is a split core current transformer designed for industrial applications. It features a primary current rating of 400 A and a secondary output of 5 A, providing a turns ratio of 400:5. The device operates within a frequency range of 50 Hz to 60 Hz. Its physical dimensions are 84 mm in height, 57.5 mm in length, and 38.5 mm in width. The unit supports free hanging installation and utilizes wire leads for termination. It functions reliably within an operating temperature range of -20 °C to +65 °C.

Feature Summary

• Split core design facilitates easy installation around existing busbars or cables without disconnecting the circuit.
• Provides accurate current measurement for integration with energy meters featuring standard 5 A current inputs.
• Constructed for free hanging mounting, allowing flexible deployment in various industrial electrical panels.

Applications

• Current measurement in combination with energy meters
• Industrial power monitoring systems
• Electrical panel instrumentation

Procurement Notes

Verify the specific part number CTA6X400A5A against official Carlo Gavazzi documentation to ensure correct specifications. Confirm that the required primary current rating of 400 A matches the application load. Check compatibility with downstream devices accepting 5 A secondary outputs. Ensure environmental conditions fall within the specified temperature range. Review the latest datasheet for any updates on mechanical dimensions or terminal types before finalizing procurement.

Selection Notes

Select this model when a 400 A primary current rating is required for split-core current sensing. Ensure the system operates at 50 Hz or 60 Hz frequencies. Verify that the available space accommodates the specified housing dimensions. Confirm that the connected metering equipment accepts 5 A secondary signals. Consider the free-hanging installation style if DIN rail mounting is not suitable for the specific enclosure layout.

Part Context

This component belongs to the CTA6X series of split core current transformers manufactured by Carlo Gavazzi. The series is engineered for industrial automation and power management tasks. Similar models in the lineup include variants with different primary current ratings, such as the CTA6X200A5A and CTA6X300A5A, which share similar form factors and operational principles but differ in their current handling capacities.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When seeking alternatives, compare key parameters including the 400:5 turns ratio, 5 A secondary output, and split core architecture. Ensure any replacement matches the physical hole diameter and mounting constraints of the existing installation.
