7SHT-162

Current Sense Transformers Overview

The Sifam Tinsley Instrumentation Inc. model 7SHT-162 is a non-ANSI rated window type current transformer designed for chassis mounting applications. It features a primary input current of 1600 A and provides a secondary output current of 5 A, establishing a transformation ratio of 1600:5. The device operates within a frequency range of 50 Hz to 400 Hz and includes a window diameter of 2.5 inches (approximately 63.5 mm). This component serves as an electrical sensing element for monitoring alternating current in industrial power systems.

Current Sense Transformers Feature Summary

• Window type construction allows for direct conductor passage without circuit interruption
• Chassis mounting design facilitates secure installation within control panels or switchgear
• Provides isolated secondary current signal proportional to high primary current levels

Current Sense Transformers Applications

• Industrial power monitoring systems requiring current sensing
• Electrical panel integration for metering circuits
• Switchgear instrumentation for AC current measurement

Current Sense Transformers Procurement Notes

Verify the specific application requirements against the non-ANSI rating classification before procurement. Confirm that the operating frequency range of 50 Hz to 400 Hz aligns with the system's electrical parameters. Ensure the chassis mounting dimensions are compatible with the intended enclosure space. Cross-reference the 1600:5 ratio with existing metering or protection device inputs to guarantee signal compatibility.

Current Sense Transformers Selection Notes

Select this component when a robust, non-ANSI rated current transformer is required for chassis-mounted installations. The 1600:5 ratio suits applications involving high primary currents up to 1600 A. Consider the 2.5-inch window size to ensure adequate clearance for the primary conductor. Evaluate the 50 Hz to 400 Hz operational bandwidth against the target system frequency to prevent measurement inaccuracies.
