2SFT-151

Overview

The Sifam Tinsley Instrumentation Inc. 2SFT-151 is a non-ANSI rated window type current transformer designed for power monitoring applications. It features a primary-to-secondary ratio of 150:5 and meets Class 1 accuracy standards. The unit supports frequency ranges from 50Hz to 400Hz with a burden rating of 4 VA. It has a circular aperture diameter of 28.7 mm and is intended for panel mount installation.

Feature Summary

• Window type construction for easy conductor insertion
• Class 1 accuracy for reliable metering
• Wide frequency range support

Applications

• Power monitoring systems
• Electrical metering panels
• Industrial power distribution

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure compatibility with required terminal configurations or lead lengths. Confirm that the non-ANSI rating aligns with project specifications, as ANSI-rated alternatives such as the 6SFT series may be necessary for certain regulatory compliance requirements.

Selection Notes

Select this component when a non-ANSI rated current transformer is specified for general power monitoring. Ensure the conductor size fits within the 28.7 mm aperture. Compare with ANSI-rated models like the 6SFT-151 if strict adherence to ANSI standards is required for the application environment.

Part Context

This part belongs to the Sifam Tinsley current transformer family, which provides electrical measuring instruments compliant with international standards. The company offers both digital and analog solutions backed by engineering support.

Replacement Considerations

The 6SFT-151 is an ANSI-rated alternative with similar 150:5 ratio capabilities. Verify interface and mounting requirements before substitution.
