Current Sense Transformers Procurement Notes

Verify the specific datasheet version for the 5SFT-251 to confirm insulation ratings and terminal configurations. Ensure the application environment falls within the specified frequency limits of 50 Hz to 400 Hz. Cross-reference the 40 mm aperture size with the actual conductor diameter to guarantee proper fit and mechanical stability during operation.

Current Sense Transformers Selection Notes

Select this model when a non-ANSI rated solution is required for precise current sensing. The 250:5 ratio suits applications where secondary instrumentation expects a 5 A input. Consider the 10 VA burden limit when calculating total connected load. The wide frequency range supports variable speed drive environments or specialized AC sources beyond standard utility frequencies.
