Procurement Notes
Verify the specific manufacturer part number against official CR Magnetics documentation to ensure authenticity. Confirm that the required frequency range and current rating align with system specifications before procurement. Check for any ordering suffixes that may indicate variations in secondary winding or accuracy class, as these affect functional compatibility.
Selection Notes
Select this component when a non-invasive sensing solution is required for high-current AC applications up to 500 A. Ensure the operating environment supports chassis mounting and that the system frequency falls within the 50Hz to 400Hz operational window. Validate mechanical fitment and electrical interface requirements against the official datasheet parameters.
Part Context
This model belongs to the CR7 series of current sense transformers from CR Magnetics Inc., which provides commercial class components for energy monitoring. The series includes variants with different current ratings, such as the CR7SFT-151 and CR7SFT-601, offering scalable solutions for various power measurement needs.
Replacement Considerations
Consider the CR7SFT-201 or CR7SFT-601 if alternative current ratings are needed. Verify that substitute models maintain compatible mounting types and frequency ranges. Cross-reference official substitution lists to ensure electrical performance equivalence.
