CR8350-2500-N3

Overview

The CR8350-2500-N3 is a current sense transformer from the CR8300 series manufactured by CR Magnetics Inc. It features a split-core design suitable for through-hole mounting with trimmed leads. The component operates within a frequency range of 20Hz to 200kHz and supports a rated primary current of 100A. It provides a current ratio of 2500:1 and exhibits a DC resistance of 32 ohms. The physical dimensions are 1.476 inches in length, 0.551 inches in width, with a maximum seated height of 1.535 inches. The device is RoHS compliant and classified under EAR99.

Feature Summary

• Split-core construction allows for non-invasive installation around existing conductors without circuit interruption.
• Trimmed lead configuration facilitates standard through-hole PCB assembly processes.
• Wide frequency bandwidth supports accurate signal sensing across low to medium frequency ranges.

Applications

• Current monitoring in industrial drive systems
• Power quality analysis in smart grid infrastructure
• Protection circuits in renewable energy inverters

Procurement Notes

Verify the specific suffix N3 against the manufacturer datasheet to confirm lead trimming specifications and packaging details. Ensure the split-core mechanical interface matches the target conductor diameter for proper magnetic coupling. Cross-reference the RoHS status with regional compliance requirements prior to final procurement authorization.

Selection Notes

Select this model when a non-invasive sensing solution is required for high-current applications up to 100A. The split-core design is essential for retrofitting or testing scenarios where breaking the primary circuit is not feasible. Confirm that the operating frequency range aligns with the signal characteristics of the monitored power source.

Part Context

This component belongs to the CR8300 series of current sense transformers, which are engineered for precision measurement in demanding electrical environments. The series emphasizes high isolation and linear response, making it suitable for applications requiring reliable current feedback. The specific variant differs from solid-core models by offering easier installation flexibility.

Replacement Considerations

Direct substitutes include other CR Magnetics split-core transformers with matching 100A ratings and similar frequency responses. Verify mechanical fitment and lead spacing when considering alternatives from different manufacturers to ensure compatibility with existing PCB layouts.
