5SFT-600

Overview

The Instrument Transformers 5SFT-600 is a solid-core current transformer designed for panel mounting. It features a 60:5 turns ratio, supporting an input current of 60A with a secondary output of 5A. The unit operates within a frequency range of 50Hz to 400Hz and provides insulation up to 600V. This component is engineered for integration with electrical measuring instruments.

Feature Summary

• Solid-core construction for reliable current sensing
• Panel mount design for secure installation
• Wide frequency operation capability

Applications

• Integration with ammeters
• Connection to wattmeters
• Cross-current compensation systems

Procurement Notes

Verify the specific manufacturer designation, as the 5SFT series is associated with multiple entities including Sifam Tinsley and Crompton Instruments. Confirm that the required insulation level matches the 600V specification and ensure the frequency range aligns with the application's operational requirements before finalizing procurement.

Selection Notes

Select this model when a 60:5 ratio is required for low-voltage applications up to 600V. Ensure the operating frequency falls between 50Hz and 400Hz. Consider the physical dimensions for panel cutouts and verify compatibility with standard metering inputs requiring 5A secondary current.

Part Context

The 5SFT series represents a line of solid-core current transformers from Instrument Transformers Inc. These devices are part of the 5 Series family, designed specifically for use with electrical meters and measuring equipment in industrial settings.

Replacement Considerations

The 5SFT-601 serves as a related variant within the same series, offering a different current ratio (600:5). Verify if the higher primary current capacity of the 601 model is suitable or if the original 60A rating is strictly required.
