CR7RL-801

Overview

The CR7RL-801 is a commercial grade AC current transformer manufactured by CR Magnetics Inc. Designed for non-invasive current sensing, this donut-style component features a solid core with a 2.5-inch inner diameter. It supports an input range of 0 to 800 AAC and provides a proportional output of 0 to 5 AAC, maintaining an 800:5 current ratio. The unit operates within a frequency range of 50Hz to 400Hz and includes two 2-foot 16AWG fly leads for connection. With free-hanging in-line mounting capabilities, it measures 1.100 inches in height.

Feature Summary

• Non-invasive solid core design for direct conductor insertion
• Commercial grade construction suitable for general industrial applications
• Integrated 16AWG fly leads for simplified wiring integration

Applications

• Industrial motor protection circuits
• Power distribution monitoring systems
• Electrical panel current measurement

Procurement Notes

Verify the specific lead time requirements against current supplier availability, as standard lead times may vary. Confirm that the commercial grade classification meets the environmental and safety standards required for your specific installation. Ensure the 800A primary current rating aligns with the maximum expected load in the target circuit to prevent saturation or damage during peak operation conditions.

Selection Notes

Select this model when a high-capacity, non-invasive solution is required for frequencies between 50Hz and 400Hz. The 2.5-inch ID accommodates large conductors without requiring busbar modification. Consider the 800:5 ratio for compatibility with standard 5A secondary instrumentation. The free-hanging mount allows flexible positioning within enclosures where space constraints preclude bolted installations.

Part Context

This component belongs to the CR7 series of current sense transformers from CR Magnetics Inc. The series focuses on providing reliable AC current measurement solutions for commercial and industrial environments. The CR7RL-801 specifically addresses high-current applications up to 800A, offering a robust alternative to invasive shunt-based measurement methods in power monitoring infrastructure.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. When replacing existing units, ensure the new component matches the 2.5-inch ID and 800:5 ratio to maintain system compatibility. Verify that the replacement supports the same 50Hz to 400Hz frequency range and utilizes compatible 16AWG lead connections.
