5SFT-201

Overview

The Sifam Tinsley Instrumentation Inc. model 5SFT-201 is a precision current sense transformer designed for panel mounting applications. It features a primary current rating of 200 A and a secondary output ratio of 200:5, delivering a standard 5 A secondary current. The device operates within a frequency range of 50 Hz to 400 Hz and supports a maximum voltage of 600 V. Constructed with a foot mount configuration and terminal connections, it includes an inner diameter of 1.56 inches. The unit complies with RoHS standards and adheres to Omega ANSI specifications for industrial instrumentation.

Feature Summary

• Provides accurate current sensing through a 200:5 transformation ratio for industrial monitoring
• Features a robust foot mount design with integrated terminals for secure panel installation
• Operates effectively across a wide frequency spectrum from 50 Hz to 400 Hz
• Complies with RoHS environmental standards and Omega ANSI technical requirements

Applications

• Industrial power distribution systems requiring precise current monitoring
• Electrical panel boards for AC current measurement up to 200 A
• Frequency variable applications operating between 50 Hz and 400 Hz
• Safety and control circuits utilizing 5 A secondary outputs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct terminal configuration and mounting style. Confirm that the required inner diameter of 1.56 inches matches the conductor size in your application. Check for compliance with local safety regulations regarding 600 V rated equipment. Ensure the operating frequency range of 50 Hz to 400 Hz aligns with your system's power source characteristics before finalizing procurement.

Selection Notes

Select this component when a 200 A primary current capacity is required for panel-mounted installations. The 200:5 ratio makes it suitable for connecting to standard ammeters or protection relays expecting a 5 A input. Consider the 600 V insulation rating for medium-voltage applications. Verify that the physical dimensions and foot mount style fit the available panel space. This model is appropriate for environments where frequencies may vary between 50 Hz and 400 Hz.

Part Context

The 5SFT series represents Sifam Tinsley's line of Omega-style current transformers, widely recognized in industrial instrumentation for reliability. These devices are engineered to meet ANSI C39.1 standards for electrical measuring instruments. The 5SFT-201 specifically addresses high-current applications where direct connection to measuring devices is impractical. Its design emphasizes accuracy and durability in demanding electrical environments.

Replacement Considerations

Direct replacements must match the 200:5 ratio, 200 A primary rating, and 50-400 Hz frequency range. Verify compatibility with the 1.56-inch inner diameter and foot mount configuration. Ensure the replacement unit supports 600 V operation and provides identical terminal connectivity. Cross-reference with other manufacturers' Omega-style transformers for dimensional and electrical equivalence.
