CR7ARL-301

Current Sense Transformers Overview

The CR7ARL-301 is an AC current transformer from CR Magnetics Inc., designed for ANSI metering class applications. It features a donut-style, non-invasive solid core construction with a 2.5-inch inner diameter. The unit accepts an input range of 0 to 300 AAC and provides a proportional output of 0 to 5AAC. It operates within a frequency range of 50Hz to 400Hz and includes two 2-foot long 16AWG fly leads for connection.

Current Sense Transformers Feature Summary

• ANSI metering class accuracy for precise energy monitoring
• Non-invasive solid core design for easy installation around conductors
• Integrated 16AWG fly leads for direct wiring connectivity

Current Sense Transformers Applications

• Commercial and industrial energy metering systems
• Power quality monitoring equipment
• Electrical distribution panel instrumentation

Current Sense Transformers Procurement Notes

Verify the specific application requirements against the 0-300A input and 0-5A output specifications before procurement. Confirm that the conductor size fits within the 2.5-inch inner diameter. Ensure the operating frequency falls within the 50Hz to 400Hz range. Check lead length compatibility with the installation layout. Validate that the metering class meets the regulatory standards for the intended deployment environment.

Current Sense Transformers Selection Notes

Select this component when high-accuracy ANSI metering is required for AC currents up to 300A. The donut style is suitable for retrofitting or new installations where non-invasive sensing is preferred. Consider the 5A output standard compatibility with downstream measurement devices. Evaluate the physical space constraints relative to the 2.5-inch ID and lead lengths. Compare against other models in the CR7ARL series if different current ratings are needed.

Current Sense Transformers Part Context

This part belongs to the CR7ARL series of AC current transformers by CR Magnetics Inc. The series offers various current ratings while maintaining consistent donut-style construction and ANSI metering class performance. Other variants in the line include models like CR7ARL-251 and CR7ARL-801, which differ primarily in their input current ranges but share similar form factors and functional characteristics.

Current Sense Transformers Replacement Considerations

Direct substitutes within the same series include the CR7ARL-251 and CR7ARL-801, though these have different input current ratings (250A and 800A respectively). Ensure any replacement matches the 0-5A output specification and 2.5-inch ID requirement. Verify that the alternative part maintains the ANSI metering class designation for equivalent accuracy.
