Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to ensure correct ratio and accuracy specifications. Confirm that the primary conductor size fits within the 4.25-inch sensing window. Check compliance requirements such as UL or IEC standards relevant to your regional electrical codes before finalizing procurement.

Selection Notes

Select this component when high-current AC measurement is required without circuit interruption. Ensure the system frequency falls within the 50-400 Hz range. Verify that the connected metering device accepts a 5 A secondary input. Consider the physical mounting constraints for free-hanging in-line installation during system design.

Part Context

This model belongs to the broader category of current sense transformers from Sifam Tinsley. It serves as a critical interface between high-voltage primary circuits and low-voltage secondary measurement instruments. The design prioritizes safety by isolating the measuring equipment from high-energy conductors while maintaining signal integrity.
