CTA5X200A5A

Overview

The Carlo Gavazzi CTA5X200A5A is a split-core industrial current transformer designed for electrical monitoring applications. It features a primary current rating of 200 A and a secondary output of 5 A, resulting in a turns ratio of 200:5. The device operates within a frequency range of 50 Hz to 60 Hz and utilizes wire leads for termination. Physically, it measures 45.2 mm in length, 34 mm in width, and 65.2 mm in height, with a bore diameter of 24 mm to accommodate conductors. It supports free-hanging installation and functions reliably within an operating temperature range of -20 °C to +65 °C.

Feature Summary

• Split-core design enables installation around existing busbars or cables without disconnecting the circuit.
• Provides a standardized 5 A secondary output compatible with standard industrial ammeters and power analyzers.
• Compact dimensions facilitate integration into confined electrical panels and switchgear enclosures.

Applications

• Industrial power distribution monitoring
• Electrical panel metering systems
• Energy management and load analysis

Procurement Notes

Verify specific regional availability and shipping restrictions prior to ordering, as distribution status varies by location. Confirm that the required 24 mm bore diameter matches the conductor size in the target application. Ensure the system voltage does not exceed the component's insulation ratings. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and access to official technical documentation.

Selection Notes

Select this model when a non-intrusive measurement solution is required for circuits carrying up to 200 A at 50/60 Hz. The split-core architecture is essential for retrofitting existing installations where cable disconnection is impractical. Choose this variant over solid-core models if space constraints prevent full loop-through installation. Verify compatibility with downstream 5 A rated instruments before finalizing the selection.

Part Context

This component belongs to the Carlo Gavazzi CTA series of current transformers, which are engineered for industrial sensing tasks. The series offers various primary current ratings and core configurations to suit different load requirements. The CTA5X200A5A specifically addresses mid-range current monitoring needs with a balance of compact form factor and reliable signal transformation for standard industrial interfaces.

Replacement Considerations

Direct substitutes include other Carlo Gavazzi CTA series units with identical 200 A primary ratings and 5 A outputs, such as CTA5X100A5A or CTA5X300A5A if current ranges allow adjustment. Ensure any replacement maintains the 24 mm bore diameter and split-core topology to fit existing mounting infrastructure without modification.

FAQ

What is the maximum conductor diameter supported by this transformer?

The device features a 24 mm bore diameter, allowing it to encircle conductors or busbars up to this size.

Can this unit be installed on live circuits?

Yes, the split-core design allows the transformer to be opened and clamped around an existing conductor without interrupting the power supply.

What is the secondary output specification?

The transformer provides a 5 A secondary current output corresponding to the 200 A primary input.
