CR8349-1500-N

Overview

The CR8349-1500-N is a non-invasive current sense transformer from the CR8300 series, manufactured by CR Magnetics Inc. It features a solid core design with a 1500:1 turns ratio and supports input currents up to 75 Arms. The device operates within a frequency range of 20Hz to 1kHz and has a DC resistance of 32 ohms. Designed for through-hole mounting, it utilizes PC pin termination. Physical dimensions are 26.00mm in length, 17.00mm in width, and 28.00mm in maximum height.

Feature Summary

• Non-invasive solid core construction for direct conductor insertion
• High isolation capability suitable for sensitive measurement circuits
• Through-hole PCB mounting for robust mechanical stability

Applications

• Motor drive current monitoring
• Power supply feedback loops
• Industrial automation control systems

Procurement Notes

Verify the specific model suffix against the manufacturer's latest datasheet to ensure compatibility with required insulation ratings and thermal performance. Confirm that the solid core aperture matches the target conductor diameter prior to integration into the printed circuit board layout.

Selection Notes

Select this component when a high turns ratio is required for low-level signal extraction from moderate current levels. Ensure the operating frequency falls within the specified 20Hz to 1kHz range. Validate that the physical footprint accommodates the through-hole pins and vertical clearance requirements of the assembly.

Part Context

This part belongs to the CR8300 series of general-purpose current transformers. It shares the same form factor and electrical characteristics as other variants in the family, differing primarily in the turns ratio to accommodate different primary current ranges while maintaining consistent secondary output behavior.

Replacement Considerations

Direct substitutes include CR8349-1000-N and CR8349-2500-N. These alternatives offer identical physical dimensions and mounting styles but provide different turns ratios (1000:1 and 2500:1 respectively). Circuit scaling must be adjusted accordingly.
