CR7ARL-501

Current Sense Transformers Overview

The CR7ARL-501 is an AC current transformer designed for ANSI metering class applications. It features a donut-style, non-invasive solid core construction with a 2.5-inch inner diameter. The device supports an input range of 0 to 500 AAC and provides a corresponding output range of 0 to 5AAC. It utilizes a 500:5 turns ratio and operates within a frequency range of 50 Hz to 400 Hz. The unit is equipped with two 2-foot fly leads made of 16AWG wire for connection.

Current Sense Transformers Feature Summary

• ANSI metering class accuracy for precise electrical measurement
• Non-invasive donut style design for easy installation around conductors
• Provides galvanic isolation between primary circuit and secondary monitoring equipment

Current Sense Transformers Applications

• Commercial and industrial energy monitoring systems
• Electrical panel metering and power distribution analysis
• Utility revenue metering applications requiring ANSI compliance

Current Sense Transformers Procurement Notes

Verify the specific application requirements against the ANSI metering class designation to ensure compliance with local regulatory standards. Confirm that the conductor size fits within the 2.5-inch inner diameter and that the operating frequency falls within the 50-400 Hz range. Ensure the 16AWG fly lead length meets the installation distance requirements between the transformer and the measuring instrument.

Current Sense Transformers Selection Notes

Select this component when high-accuracy current measurement is required for AC systems up to 500A. The donut style allows for retrofitting into existing busbars or cables without breaking the circuit. Consider the physical dimensions of the inner diameter to ensure compatibility with the target conductor. The 500:5 ratio is standard for connecting to ammeters or data acquisition systems designed for 5A inputs.

Current Sense Transformers Part Context

This model belongs to the CR Magnetics ARL series of AC current transformers. These components are engineered for professional energy monitoring environments. The series offers various inner diameters and ratios to accommodate different current levels and physical constraints. The CR7ARL-501 specifically addresses higher current ranges while maintaining strict metering accuracy standards.

Current Sense Transformers Replacement Considerations

Direct substitutes must match the 500:5 ratio, 2.5-inch ID, and ANSI metering class specifications. Verify that any alternative part supports the same 50-400 Hz frequency range and provides compatible 16AWG fly leads. Cross-reference the physical mounting requirements and terminal configuration to ensure seamless integration into existing setups.
