CR5RL-101

Current Sense Transformers Overview

The CR5RL-101 is a commercial class current sense transformer manufactured by CR Magnetics Inc. It features a non-invasive solid core design with a free-hanging in-line mounting type. The device supports a frequency range of 50Hz to 400Hz and has a primary current rating of 100 A. It provides a standard current ratio of 100:5, making it suitable for precise current monitoring applications within its specified electrical parameters.

Current Sense Transformers Feature Summary

• Non-invasive solid core construction allows for easy installation without circuit interruption
• Commercial class accuracy designed for general instrumentation purposes
• Free-hanging in-line mounting facilitates straightforward integration into existing wiring

Current Sense Transformers Applications

• Current monitoring in industrial power distribution systems
• Instrumentation grade measurement circuits
• Electrical safety and protection relay inputs

Current Sense Transformers Procurement Notes

Verify the specific datasheet version and compliance documentation (such as ANSI Metering Class if required) directly from the manufacturer or authorized distributor before procurement. Ensure that the application environment matches the commercial class specifications and that the operating frequency remains within the 50Hz to 400Hz range to guarantee accurate performance and reliability.

Current Sense Transformers Selection Notes

Select this component when a 100:5 current ratio and 100 A primary rating are required for non-invasive monitoring. Consider the commercial class accuracy limits and the 50Hz-400Hz frequency response. Compare against other models in the CR5RL series, such as the CR5RL-201, if higher current ratings like 200 A are needed while maintaining similar form factors and interface characteristics.

Current Sense Transformers Part Context

This part belongs to the CR5RL series of current sense transformers from CR Magnetics Inc., which offers various current ratings including 100 A, 200 A, and 500 A options. These transformers share a consistent non-invasive solid core design and in-line mounting style, providing scalable solutions for different current monitoring requirements across commercial and instrumentation applications.

Current Sense Transformers Replacement Considerations

The CR5RL-201 serves as a direct substitute variant within the same series, offering a 200:5 ratio and 200 A rating. Verify that the increased current capacity aligns with the system requirements and that the physical dimensions and pinout remain compatible with the existing PCB footprint or wiring configuration.
