Current Sense Transformers Procurement Notes

Verify the specific datasheet version from Omega Engineering to confirm mechanical dimensions and terminal configurations. Ensure the application voltage does not exceed the transformer's insulation ratings. Confirm that the load impedance connected to the secondary winding remains within the 40 VA limit to maintain Class 1 accuracy. Check for any regional compliance certifications required for your specific market deployment.

Current Sense Transformers Selection Notes

Select this model when a 200 A primary current capacity and 5 A secondary output are required for analog or digital metering. The 35 mm window size accommodates standard busbars or thick cables without modification. Consider the 40 VA power rating to ensure the connected instrument burden does not degrade accuracy. This toroidal type is suitable for fixed installations where non-invasive monitoring is preferred over shunt-based solutions.
