5SFT-750

Current Sense Transformers Overview

The Sifam Tinsley Instrumentation Inc. model 5SFT-750 is a window-type current transformer designed for electrical measurement applications. It features a non-ANSI rated construction with a primary-to-secondary turns ratio of 75:5. The device supports frequency ranges from 50Hz to 400Hz and offers a burden rating of 1.5 VA. It adheres to Class 2 accuracy standards and includes a 40 mm aperture for conductor passage. This component facilitates precise current sensing in industrial instrumentation systems.

Current Sense Transformers Feature Summary

• Window-type design for easy installation around conductors
• Non-ANSI rated construction for general purpose measurement
• Class 2 accuracy classification for reliable data output

Current Sense Transformers Applications

• Electrical panel metering systems
• Industrial power monitoring equipment
• Current sensing for protection relays

Current Sense Transformers Procurement Notes

Verify the specific accuracy class and burden requirements against your system design before ordering. Confirm that the 40 mm window size accommodates the target conductor diameter. Ensure the operating frequency range of 50Hz to 400Hz aligns with your application's electrical parameters. Check for any regional compliance certifications required by your facility.

Current Sense Transformers Selection Notes

Select this model when a 75:5 ratio is required for step-down current measurement. Consider the 1.5 VA burden limit when determining secondary load compatibility. The window type allows for retrofitting existing busbars without disconnection. Evaluate the Class 2 accuracy against higher precision needs if available.

Current Sense Transformers Part Context

This component belongs to the Sifam Tinsley 5SFT series of current transformers. The series provides various ratios and aperture sizes for different current levels. These units are typically used in conjunction with digital or analog panel meters to display real-time current values in electrical distribution networks.

Current Sense Transformers Replacement Considerations

Direct substitutes include models with identical 75:5 ratios and compatible window dimensions. Verify mechanical mounting constraints and terminal configurations when swapping components. Ensure the replacement maintains the same frequency response and accuracy class.
