CR7RL-401

Overview

The CR7RL-401 is a commercial grade AC current transformer manufactured by CR Magnetics Inc. It features a donut-style solid core design with a 2.5-inch inner diameter, suitable for non-invasive current sensing applications. The device supports an input range of 0 to 400 AAC and provides a corresponding output of 0 to 5 AAC, maintaining a 400:5 current ratio. It operates within a frequency range of 50Hz to 400Hz and utilizes free-hanging in-line mounting with two-foot 16AWG fly leads.

Feature Summary

• Non-invasive solid core construction for direct conductor insertion
• Commercial grade accuracy classification for general instrumentation
• Integrated two-foot 16AWG fly leads for flexible wiring connections

Applications

• AC power monitoring systems
• Industrial current sensing circuits
• Electrical protection relay inputs

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 commercial grade specification meets the accuracy requirements of the target application before finalizing procurement orders.

Selection Notes

Select this component when a 400A primary current rating and 5A secondary output are required for AC frequencies between 50Hz and 400Hz. Ensure the installation environment accommodates the 2.5-inch inner diameter and that the non-invasive solid core design aligns with the physical constraints of the conductor being monitored.

Part Context

This model belongs to the CR7 series of current sense transformers from CR Magnetics Inc. It is categorized as a commercial grade instrument transformer designed for robust performance in standard industrial environments without the stringent calibration requirements of metering class devices.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other CR Magnetics models in the CR7 series or consult the manufacturer for equivalent specifications if exact replacement is necessary.
