7SFT-201

Current Sense Transformers Overview

The 7SFT-201 is a window-type current transformer manufactured by Sifam Tinsley Instrumentation Inc. It features a primary current rating of 200 A and a secondary nominal current of 5 A, providing a 200:5 transformation ratio. The device operates within a frequency range of 50 Hz to 400 Hz and has a burden rating of 5 VA. It is classified as Class 1 accuracy and is non-ANSI rated. The unit includes an aperture size of 63.5 mm for panel mounting applications.

Current Sense Transformers Feature Summary

• Window-type construction designed for through-conductor installation
• Class 1 accuracy classification for measurement reliability
• Operates across a wide frequency spectrum from 50 Hz to 400 Hz
• Non-ANSI rated design suitable for specific international standards

Current Sense Transformers Applications

• Electrical power monitoring systems
• Industrial control panels requiring current sensing
• Energy management metering infrastructure
• Transformer protection circuits

Current Sense Transformers Procurement Notes

Verify that the required accuracy class (Class 1) meets the specific application tolerance requirements. Confirm that the operating frequency range of 50 Hz to 400 Hz aligns with the system's electrical characteristics. Ensure the physical aperture dimension of 63.5 mm accommodates the conductor size being monitored. Check compliance with local regulatory standards given the non-ANSI rating status.

Current Sense Transformers Selection Notes

Select this component when a 200:5 ratio is necessary for low-voltage current monitoring. Consider the 5 VA burden limit when calculating total connected load on the secondary side. Evaluate the 63.5 mm aperture against available busbar or cable dimensions. Compare against ANSI-rated alternatives if North American certification is mandatory for the project scope.

Current Sense Transformers Part Context

This model belongs to the Sifam Tinsley instrumentation portfolio, which provides measurement and control solutions. The manufacturer specializes in industrial-grade components for monitoring and protection. This specific transformer supports continuous current monitoring tasks in electrical distribution networks.

Current Sense Transformers Replacement Considerations

Direct substitutes must maintain the 200:5 ratio, 5 VA burden, and 63.5 mm aperture. Verify frequency compatibility up to 400 Hz. Cross-reference accuracy classes to ensure equivalent performance levels are maintained during replacement.
