5SFT-601

Current Sense Transformers Overview

The Sifam Tinsley Instrumentation Inc. model 5SFT-601 is an ANSI standard current transformer designed for panel mounting applications. It features a split-core construction with a 1.56-inch inner diameter, facilitating installation around conductors without disconnecting the primary circuit. The device provides a standardized secondary output ratio of 60:5 amperes, suitable for integration with metering and protection equipment operating within the 50Hz to 400Hz frequency range. Constructed for durability, it supports continuous operation in industrial electrical environments while maintaining measurement accuracy compliant with relevant international standards.

Current Sense Transformers Feature Summary

Current Sense Transformers Procurement Notes

Verify that the required primary current rating matches the specific application load before ordering. Confirm that the conductor size fits within the specified 1.56-inch inner diameter clearance. Ensure the secondary burden connected to the transformer does not exceed the rated limits defined in the official datasheet to maintain accuracy. Check for any specific mounting hardware requirements associated with the panel thickness.

Current Sense Transformers Selection Notes

Select this component when a split-core solution is necessary for retrofitting or temporary monitoring setups where breaking the primary circuit is impractical. Consider the 60:5 ratio relative to the maximum expected primary current to ensure optimal utilization of the secondary range. Evaluate the physical space constraints for panel mounting and verify that the operating frequency aligns with the system's power quality specifications.

Current Sense Transformers Part Context

This part belongs to the Sifam Tinsley 5SFT series of ANSI current transformers, which are widely used in North American industrial applications. The series offers various ratios and core sizes to accommodate different current levels and conductor dimensions.
