CR7RL-162

Overview

The CR7RL-162 is a commercial grade AC current transformer manufactured by CR Magnetics Inc. Designed for non-invasive solid core applications, this component supports an input range of 0 to 1600 AAC and provides an output range of 0 to 5 AAC. It operates within a frequency range of 50 Hz to 400 Hz. The unit features a donut style construction with a 2.5-inch inner diameter and includes two-foot, 16 AWG fly leads. It utilizes free hanging in-line mounting.

Feature Summary

• Non-invasive solid core design for direct conductor insertion
• Commercial grade performance suitable for general industrial monitoring
• Integrated long lead wires for simplified circuit integration

Applications

• Industrial motor protection systems
• Power quality monitoring equipment
• Electrical distribution panel metering

Procurement Notes

Verify the specific manufacturing date code against project requirements to ensure compliance with RoHS3 standards. Confirm that the 16 AWG wire gauge and two-foot lead length meet the physical routing constraints of the assembly. Ensure the 1.6 kA rating aligns with the maximum expected load current to prevent saturation or thermal issues during peak operation periods.

Selection Notes

Select this model when high-current measurement up to 1600 A is required without breaking the primary circuit. The donut geometry accommodates conductors fitting within the 2.5-inch ID. Consider the 50-400 Hz bandwidth limitation; it is unsuitable for high-frequency switching applications. Verify that the 0-5 A secondary output matches the input sensitivity of the connected measuring instrument or data acquisition system.

Part Context

This component belongs to the CR7 series of current sense transformers from CR Magnetics Inc. The series focuses on robust, cost-effective solutions for commercial-grade power monitoring. The CR7RL-162 specifically addresses high-amperage applications where traditional split-core sensors may lack sufficient aperture size or durability for permanent installation in heavy-duty electrical infrastructure.

Replacement Considerations

No public confirmed substitute part numbers are available.
