CT800A

Overview

The Hammond Manufacturing CT800A is a toroidal current transformer designed for indoor industrial applications. It features a chassis mount configuration with a primary current rating of 800 A and a secondary output of 5 A, providing an 800:5 turns ratio. The unit supports bare or insulated primary conductors in circuits up to 600 V. It includes two hole mounting brackets and is supplied with 24-inch insulated secondary leads terminated with crimped ring connectors.

Feature Summary

• Toroidal design suitable for bare or insulated primary conductors
• Standardized 5 A secondary output for compatibility with standard AC ammeters
• Integrated mounting hardware for secure installation

Applications

• Industrial electrical monitoring systems
• Power distribution panel metering
• Equipment requiring primary current measurement up to 800 A

Procurement Notes

Verify the specific datasheet version for the CT800A to confirm compliance with local safety standards and environmental operating conditions. Ensure that the required secondary load does not exceed the rated burden to maintain accuracy. Confirm that the primary conductor dimensions are compatible with the toroidal window size before finalizing procurement.

Selection Notes

Select the CT800A when the application requires measuring primary currents up to 800 A with a standardized 5 A secondary signal. This model is appropriate for chassis-mounted installations where space constraints favor a toroidal form factor. Consider the 24-inch lead length for routing flexibility to connected instrumentation.

Part Context

The CT800A belongs to the CT Series of small current transformers manufactured by Hammond Manufacturing. This series provides various ratios for different current levels while maintaining consistent physical dimensions and mounting styles. The CT800A specifically addresses higher current ranges within this product line.

Replacement Considerations

Direct substitutes include other Hammond CT series models with matching 800:5 ratios, such as the CT80. Verify that alternative parts support the same 600 V primary voltage rating and chassis mounting requirements.
