Current Sense Transformers Procurement Notes

Verify the specific ordering suffix to ensure correct lead length and output voltage configuration. Confirm that the 200A rating aligns with the maximum expected load current in the target circuit. Ensure the 0.77-inch aperture accommodates the conductor size without mechanical interference. Check for Measure Canada certification requirements if the application falls under Canadian regulatory jurisdiction.

Current Sense Transformers Selection Notes

Select this model when a solid core design is preferred over split-core for permanent installations. The 333mV output is suitable for interfacing with standard analog-to-digital converters or data acquisition modules. Consider the physical constraints of the 0.77-inch aperture when routing busbars or thick cables. Verify thermal stability requirements against the ambient operating conditions of the installation site.

Current Sense Transformers Part Context

This part belongs to the ACUCT series of current transformers from Automation Components, Inc. The series typically offers various aperture sizes and current ratings to suit different conductor dimensions. The S77 designation likely refers to the specific aperture dimension within the product line. Other variants may differ in output voltage or lead configurations while maintaining similar core technologies.

Current Sense Transformers Replacement Considerations

Direct substitutes must match the 200A rating, 333mV output, and 0.77-inch aperture. Verify that any replacement also holds Measure Canada approval if required. Ensure the replacement maintains the same polarity marking and frequency response characteristics. Consult manufacturer cross-reference lists for equivalent models with identical electrical specifications.
