CR7ARL-201

Current Sense Transformers Overview

The CR7ARL-201 is an AC current transformer from CR Magnetics Inc., designed for ANSI metering class applications. It features a donut-style core with a 2.5-inch inner diameter and includes two-foot 16AWG fly leads. The device supports an input range of 0 to 200 AAC and provides a corresponding output range of 0 to 5AAC. It operates within a frequency range of 50Hz to 400Hz, making it suitable for standard power line frequencies and higher harmonic environments.

Current Sense Transformers Feature Summary

• ANSI metering class accuracy for precise energy measurement
• Donut style construction allowing easy installation around conductors
• Integrated 16AWG fly leads for simplified wiring connections

Current Sense Transformers Applications

• Industrial automation systems requiring accurate current monitoring
• Power distribution panels for metering and protection
• Electrical testing equipment utilizing standard current transformers

Current Sense Transformers Procurement Notes

Verify the specific lead length and gauge requirements against the 16AWG specification before integration. Confirm that the 2.5-inch inner diameter accommodates the target conductor size without interference. Ensure the application environment falls within the specified 50Hz to 400Hz operational range to maintain ANSI metering class performance standards.

Current Sense Transformers Selection Notes

Select this model when high-precision metering is required for currents up to 200A. The donut design is ideal for retrofitting existing busbars or cables where through-hole mounting is preferred. Consider the integrated leads if discrete wire termination is desired over terminal block connections.

Current Sense Transformers Part Context

This component belongs to the CR Magnetics current sense transformer family, which specializes in isolated current measurement solutions. The CR7ARL series is engineered for robust performance in industrial settings, offering reliable isolation between primary and secondary circuits while maintaining linear response across the operating frequency spectrum.

Current Sense Transformers Replacement Considerations

Cross-reference with CR7ARL-122 or CR7ARL-251 for similar ANSI metering class specifications. Verify that alternative models match the 200A input rating and 5A output ratio to ensure compatibility with existing metering infrastructure.
