CT-1075

Overview

The CT-1075 is a current sense transformer manufactured by Amgis, LLC, designed for non-invasive AC current monitoring applications. It features a solid core construction suitable for through-hole mounting on printed circuit boards. The component operates at standard power line frequencies of 50 Hz and 60 Hz. Key electrical specifications include a primary current rating of 75 A and a secondary current ratio of 1000:1. The device exhibits a DC resistance (DCR) of 24 Ohms. Physically, the unit measures 1.500 inches in length, 0.626 inches in width, with a maximum seated height of 1.500 inches.

Feature Summary

• Non-invasive solid core design enables direct wire insertion without circuit interruption
• High isolation capability via transformer coupling for safe current sensing
• Through-hole package format ensures secure mechanical attachment to PCBs

Applications

• AC power monitoring systems requiring precise current measurement
• Industrial equipment protection circuits utilizing overcurrent detection
• Energy metering devices for residential or commercial utility tracking

Procurement Notes

Verify that the specific order quantity meets distributor minimum requirements before finalizing purchase orders. Confirm that the through-hole pin configuration matches the target PCB footprint dimensions exactly. Ensure that the operating environment remains within the specified frequency range of 50/60 Hz to maintain accurate signal transformation ratios. Check for any required surface finish compatibility if soldering processes are specialized.

Selection Notes

Select this component when a non-invasive solution is required for monitoring alternating currents up to 75 A. The 1000:1 ratio provides a scaled output suitable for downstream processing electronics. Consider the physical dimensions to ensure adequate clearance on the assembly board. Verify that the system can accommodate the 24 Ohm secondary impedance without loading errors affecting measurement accuracy.

Part Context

This part belongs to the CT series of current sense transformers produced by Amgis, LLC. The series includes various models rated for different current levels, such as the CT-1200 rated for 200 A. These components share common design principles focusing on reliable magnetic coupling for industrial and commercial power applications.

Replacement Considerations

Direct substitutes must match the 75 A rating, 1000:1 ratio, and 24 Ohm DCR. Verify that alternative parts support the same 50/60 Hz frequency operation and through-hole mounting style. Cross-reference physical dimensions to ensure board compatibility.
