8SHT-151-E

Current Sense Transformers Overview

The Littelfuse 8SHT-151-E is a current sense transformer designed for indirect AC current measurement. It steps down primary current to a usable secondary signal level. The device features a 150:5 turns ratio, indicating its transformation capability from a 150 Ampere primary input to a 5 Ampere secondary output. It is constructed with a 3.25-inch window size, allowing it to accommodate conductors of specific diameters for through-hole installation. This component serves as a passive sensing element in electrical circuits.

Current Sense Transformers Feature Summary

• Provides indirect AC current measurement by stepping down high primary currents to lower secondary levels
• Features a fixed 150:5 current transformation ratio for standardized signal output
• Designed with a 3.25-inch aperture to accept primary conductors directly

Current Sense Transformers Applications

• Industrial current monitoring systems
• Electrical protection circuitry requiring current sensing
• Power distribution equipment feedback loops

Current Sense Transformers Procurement Notes

Verify the specific manufacturer part number against official Littelfuse documentation to ensure authenticity. Confirm that the 150:5 ratio and 3.25-inch window dimensions match the design requirements. Check for any updated datasheets or revision notices that may affect mechanical or electrical specifications before finalizing procurement orders.

Current Sense Transformers Selection Notes

Select this component when a robust, through-hole current transformer is required for high-current AC applications. Ensure the primary conductor fits within the 3.25-inch window. Verify that the 150:5 ratio aligns with the downstream sensing electronics' input range. Consider mechanical mounting constraints and thermal performance relative to the expected continuous load current.

Current Sense Transformers Part Context

This part belongs to the Littelfuse current sense transformer family, specifically engineered for industrial and power management applications. These transformers are typically used where galvanic isolation between the primary circuit and the sensing electronics is necessary. The series offers various ratios and window sizes to accommodate different current levels and physical installation spaces.

Current Sense Transformers Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Ensure any replacement maintains the 150:5 ratio and compatible window size. Generic substitutes may not guarantee identical frequency response or saturation characteristics.
