CR7SFT-301

Current Sense Transformers Overview

The CR7SFT-301 is a commercial-grade AC current transformer manufactured by CR Magnetics Inc. It features a non-invasive solid core design suitable for chassis mounting. The device supports an input current range of 0 to 300 AAC and provides a corresponding output range of 0 to 5 AAC. It operates within a frequency range of 50Hz to 400Hz. The unit includes two terminals compatible with #8-32 connections and utilizes a mounting case with a 2.5-inch inner diameter.

Current Sense Transformers Feature Summary

• Non-invasive solid core construction for safe current monitoring
• Chassis mount configuration with dedicated mounting case
• Dual terminal interface supporting standard connection hardware

Current Sense Transformers Applications

• Commercial electrical panel monitoring
• Industrial power distribution measurement
• AC current sensing in control systems

Current Sense Transformers Procurement Notes

Verify the specific datasheet version for the CR7SFT-301 to confirm mechanical dimensions and terminal specifications. Ensure the application environment falls within the 50Hz to 400Hz operational range. Confirm that the chassis mounting requirements align with the 2.5-inch ID specification before finalizing procurement.

Current Sense Transformers Selection Notes

Select this component when a non-invasive solution for up to 300A AC current is required. The 300:5 ratio is standard for metering applications. Consider the chassis mount style if space constraints preclude through-hole or busbar integration. Verify thermal performance under continuous load conditions.

Current Sense Transformers Part Context

This part belongs to the CR Magnetics current sense transformer series. It shares design principles with related models like the CR2SFT-301 but differs in specific mounting and casing configurations. The product line focuses on reliable AC current measurement for commercial and industrial grade applications.

Current Sense Transformers Replacement Considerations

Direct substitutes may include other CR Magnetics models within the same series offering identical 300:5 ratios. Verify mechanical fitment and terminal compatibility when considering alternative manufacturers. Cross-reference datasheets to ensure equivalent frequency response and accuracy classes.
