5SHT-301

Current Sense Transformers Overview

The Sifam Tinsley Instrumentation Inc. model 5SHT-301 is a current sense transformer designed for chassis mounting applications. It features a primary-to-secondary turns ratio of 300:5, enabling the measurement of up to 300 A primary current. The device operates within a frequency range of 50 Hz to 400 Hz, supporting standard power and industrial frequencies. This component serves as a sensing element for electrical monitoring systems requiring precise current transformation.

Current Sense Transformers Feature Summary

• Provides electrical isolation between high-current primary circuits and low-current secondary sensing outputs
• Engineered for direct chassis mounting to facilitate integration into panel-based instrumentation enclosures
• Capable of accurate signal transformation across a defined frequency spectrum from 50 Hz to 400 Hz

Current Sense Transformers Applications

• Current monitoring in industrial power distribution panels
• Integration with ammeters and energy meters for AC circuit analysis
• Electrical protection relay input conditioning

Current Sense Transformers Procurement Notes

Verify that the required operating frequency falls strictly within the 50 Hz to 400 Hz specification before procurement. Confirm that the mechanical dimensions align with the designated chassis mounting cutout. Ensure the primary current rating of 300 A matches the maximum expected load in the target application circuit to prevent saturation or damage.

Current Sense Transformers Selection Notes

Select this component when a robust, isolated current sensing solution is required for fixed installations. The 300:5 ratio is suitable for interfacing with standard 5 A secondary instruments. Consider the chassis mount form factor if space constraints preclude PCB-mounted alternatives. Validate that the environmental conditions of the installation site are compatible with the transformer's operational limits.
