CR2RL-500

Current Sense Transformers Overview

The CR2RL-500 is a commercial-grade AC current transformer designed for non-invasive solid-core monitoring. It features a donut-style construction with a 1.13-inch inner diameter window, accommodating conductors up to 50 A primary input. The device provides a 50:5 current ratio, delivering a maximum secondary output of 5 A. It operates within a frequency range of 50 Hz to 400 Hz and maintains 3% accuracy at 60 Hz. The unit utilizes chassis mounting and includes two 2-foot 16 AWG fly leads for connection.

Current Sense Transformers Feature Summary

• UL recognized safety certification for commercial applications
• Fixed 50:5 current transformation ratio

Current Sense Transformers Applications

• Industrial motor protection circuits
• Power distribution panel metering
• Electrical load monitoring systems
• Commercial HVAC control interfaces

Current Sense Transformers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct lead length and termination type. Confirm that the application environment remains within the specified 50 Hz to 400 Hz frequency range. Ensure the primary conductor size fits within the 1.13-inch window without exceeding the 50 A thermal rating. Check for UL recognition requirements in your target market compliance standards before finalizing procurement.

Current Sense Transformers Selection Notes

Select this component when a non-invasive, commercial-grade solution is required for currents up to 50 A. The fixed 50:5 ratio suits standard ammeter inputs or relay coils requiring 5 A secondary current. Consider the chassis mount requirement and available space for the 1.13-inch aperture. This model is appropriate for frequencies between 50 Hz and 400 Hz, making it suitable for standard power and variable frequency drive outputs.

Current Sense Transformers Part Context

This part belongs to the CR Magnetics CR series of current sense transformers. These components are engineered for reliable electrical isolation and accurate signal transfer in industrial environments. The series typically offers various ratios and window sizes to accommodate different current levels and conductor geometries while maintaining consistent performance characteristics across the product line.

Current Sense Transformers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility by matching the 50:5 ratio, 50 A primary rating, 1.13-inch window diameter, and 50-400 Hz frequency range with alternative manufacturers' datasheets.
