CR2SFT-750

Current Sense Transformers Overview

The CR2SFT-750 is an AC current transformer manufactured by CR Magnetics Inc., designed for commercial grade applications. It features a solid core, non-invasive design with a chassis mounting case and two #8-32 terminals. The device operates within a frequency range of 50Hz to 400Hz. It supports an input current range of 0 to 75 AAC and provides an output range of 0 to 5AAC. The unit has a 1.13-inch inner diameter and maintains a current ratio of 75:5.

Current Sense Transformers Feature Summary

• Non-invasive solid core construction for easy installation around conductors
• Chassis mount design with standard #8-32 terminal connections
• Commercial grade performance suitable for general AC current sensing

Current Sense Transformers Applications

• AC current monitoring in commercial electrical systems
• Power quality analysis within the 50Hz to 400Hz frequency range
• Current sensing for protection circuits requiring 75A primary rating

Current Sense Transformers Procurement Notes

Verify the specific lot number and physical condition when sourcing NOS or surplus units. Confirm that the terminal configuration matches your existing panel layout requirements. Ensure the operating frequency range aligns with your system's power source specifications before finalizing procurement decisions.

Current Sense Transformers Selection Notes

Select this component when a non-invasive solution is required for currents up to 75A. The 75:5 ratio is standard for interfacing with measurement devices expecting 5A secondary inputs. Consider the chassis mount style if space constraints preclude PCB mounting options.

Current Sense Transformers Part Context

This part belongs to the CR Magnetics SFT series of current sense transformers. These components are engineered for reliable AC current measurement in industrial and commercial environments. The series offers various current ratings and aperture sizes to accommodate different conductor dimensions.

Current Sense Transformers Replacement Considerations

Direct substitutes must match the 75:5 ratio, 75A primary rating, and chassis mount form factor. Verify terminal types and inner diameter compatibility. Cross-reference with other manufacturers offering solid core current transformers with similar electrical specifications.
