CR7ARL-152

Current Sense Transformers Overview

The CR7ARL-152 is an AC current transformer from CR Magnetics Inc., designed for non-invasive current sensing applications. It features a donut-style solid core construction with a 2.5-inch inner diameter, allowing it to be installed around conductors without breaking the circuit. The device supports an input range of 0 to 1500 AAC and provides a corresponding output range of 0 to 5 AAC. It operates within a frequency range of 50Hz to 400Hz and is classified under ANSI Metering standards. The unit includes two 2-foot long 16AWG fly leads for connection and utilizes a free-hanging in-line mounting type.

Current Sense Transformers Feature Summary

• Non-invasive donut style design for through-conductor installation
• ANSI metering class accuracy for reliable measurement
• High current capacity supporting up to 1500 AAC input
• Integrated 2-foot 16AWG fly leads for simplified wiring

Current Sense Transformers Applications

• Industrial power monitoring systems
• Electrical panel metering
• Motor protection circuits
• Energy management solutions

Current Sense Transformers Procurement Notes

Verify that the required inner diameter accommodates the specific conductor size, as the CR7ARL-152 has a fixed 2.5-inch ID. Confirm that the operating frequency falls within the 50Hz to 400Hz range specified for this model. Ensure the application requires an ANSI metering class rating rather than a protection class variant. Check that the 16AWG lead length meets the installation distance requirements between the transformer and the measuring instrument.

Current Sense Transformers Selection Notes

Select this component when a high-current, non-invasive sensing solution is needed for frequencies up to 400Hz. The 2.5-inch bore size is suitable for large busbars or thick cables. Consider the 0-5A secondary output compatibility with standard ammeters or data acquisition systems. This model is appropriate for applications requiring ANSI compliance for billing or precise monitoring purposes.

Current Sense Transformers Part Context

This part belongs to the CR7ARL series of AC current transformers by CR Magnetics Inc. The series offers various bore sizes and current ratings to suit different conductor dimensions and load requirements. The '152' suffix typically denotes the specific current ratio and physical configuration within the product line.

Current Sense Transformers Replacement Considerations

Direct substitutes must match the 1500:5 ratio, 2.5-inch ID, and ANSI metering class. Verify frequency response compatibility for 50-400Hz operation. Cross-reference mechanical dimensions to ensure fit within existing panel spaces.
