CR7ARL-102

Current Sense Transformers Overview

The CR7ARL-102 is a non-invasive solid core AC current transformer manufactured by CR Magnetics Inc. It operates within a frequency range of 50Hz to 400Hz and supports an input current range of 0 to 1000 AAC with an output range of 0 to 5AAC. The unit features a donut style design with a 2.5-inch inner diameter and includes two 2-foot 16AWG fly leads. Classified under ANSI Metering standards, it is designed for free hanging in-line mounting.

Current Sense Transformers Feature Summary

• Non-invasive solid core construction for direct conductor insertion
• ANSI Metering Class certification for accurate measurement
• Donut style geometry accommodating large conductors

Current Sense Transformers Applications

• Energy monitoring systems
• Power quality analysis
• Industrial metering applications

Current Sense Transformers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure compatibility with required lead lengths or mounting configurations. Confirm that the 16AWG fly leads meet the gauge requirements of your downstream instrumentation. Cross-reference the ANSI Metering Class designation with your facility's calibration standards to ensure regulatory compliance for billing or monitoring purposes.

Current Sense Transformers Selection Notes

Select this component when high-current measurement up to 1000A is required without interrupting the circuit. Ensure the primary conductor fits within the 2.5-inch ID aperture. Verify that the operating frequency falls within the 50Hz to 400Hz range. Consider the free-hanging in-line mounting style for installation flexibility in panel boards or switchgear assemblies where space constraints allow.

Current Sense Transformers Part Context

This model belongs to the CR7ARL series of current sense transformers from CR Magnetics Inc., a provider of energy monitoring sensors. The series includes variants such as the CR7ARL-251 and CR7ARL-801, which share similar donut-style architectures but differ in current ratings and physical dimensions. These components are part of a broader line including voltage transducers and power factor sensors.
