CR7ARL-801

Current Sense Transformers Overview

The CR7ARL-801 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 unit supports an input range of 0 to 800 AAC and provides a proportional output of 0 to 5AAC. Operating within a frequency range of 50Hz to 400Hz, it utilizes 2-foot 16AWG fly leads for connection. The device is rated for free-hanging or in-line installation.

Current Sense Transformers Feature Summary

• ANSI metering class accuracy for precise electrical measurement
• Non-invasive solid core design allowing easy circuit integration
• Wide frequency response suitable for standard power and industrial frequencies

Current Sense Transformers Applications

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

Current Sense Transformers Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct lead length and termination style. Confirm that the required ANSI metering class rating aligns with your system's precision requirements. Check physical dimensions against panel cutout specifications to ensure proper fitment during installation.

Current Sense Transformers Selection Notes

Select this model when high-current measurement up to 800A is required without breaking the primary conductor. The 5A secondary output is compatible with standard ammeter inputs. Ensure the operating frequency falls within the 50Hz to 400Hz range for optimal performance and accuracy.

Current Sense Transformers Part Context

This component belongs to the CR7ARL series of AC current transformers from CR Magnetics. The series offers various input ranges tailored for different current levels while maintaining consistent ANSI metering class standards. The donut style provides a robust solution for permanent installations in electrical infrastructure.

Current Sense Transformers Replacement Considerations

Direct substitutes must match the 800:5 ratio, 2.5-inch ID, and ANSI metering class. Verify frequency compatibility and lead length requirements before swapping. Cross-reference mechanical mounting constraints to ensure interchangeability without redesigning the enclosure.
