CR2RL-151

Current Sense Transformers Overview

The CR2RL-151 is a commercial-grade AC current transformer manufactured by CR Magnetics Inc. It features a donut-style core with a 1.13-inch inner diameter window. The device supports an input range of 0 to 150 AAC and provides a corresponding output range of 0 to 5 AAC, establishing a coil ratio of 150:5. It operates within a frequency range of 50Hz to 400Hz and maintains 1% accuracy at 60 Hz. The unit includes two 2-foot long 16AWG fly leads for connection.

Current Sense Transformers Feature Summary

• Donut-style construction for through-wire installation
• Commercial grade classification for general applications
• Integrated 16AWG fly leads for simplified wiring

Current Sense Transformers Applications

• AC current sensing in power monitoring systems
• Industrial control circuits requiring current feedback
• Energy metering equipment

Current Sense Transformers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure compatibility with required insulation ratings or lead configurations. Confirm that the commercial grade classification meets the thermal and safety requirements of the intended deployment environment before finalizing procurement.

Current Sense Transformers Selection Notes

Select this component when a 150A primary current rating and 5A secondary output are required for AC measurements. Ensure the operating frequency falls within the 50Hz to 400Hz range. The 1.13-inch window diameter dictates the maximum conductor size that can pass through the transformer core during installation.

Current Sense Transformers Part Context

This part belongs to the CR Magnetics CR2RL series of current sense transformers. These components are designed for non-invasive AC current measurement in commercial and industrial settings. The series offers various ratios and window sizes to accommodate different current levels and conductor dimensions.

Current Sense Transformers Replacement Considerations

Direct substitutes must match the 150:5 ratio, 1.13-inch ID, and 5A secondary output. Verify frequency response and accuracy specifications against the original datasheet to maintain system performance integrity.
