CR5ARL-301

Current Sense Transformers Overview

The CR5ARL-301 is a current sense transformer manufactured by CR Magnetics Inc., designed for high-current measurement applications. It features a rated primary current of 300 A and operates within a frequency range of 50 Hz to 400 Hz. The component utilizes a free-hanging in-line mounting configuration, allowing it to be installed directly into the conductor path without additional mechanical fixtures. This design supports precise signal isolation and accurate current monitoring in industrial power systems.

Current Sense Transformers Feature Summary

• Provides electrical isolation between high-voltage primary circuits and low-voltage secondary sensing circuits
• Supports in-line installation for direct conductor integration without external brackets
• Maintains signal integrity across a wide frequency bandwidth from 50 Hz to 400 Hz

Current Sense Transformers Applications

• Industrial motor drive current monitoring
• Power converter input/output current sensing
• Uninterruptible power supply (UPS) system protection

Current Sense Transformers Procurement Notes

Verify that the supplier provides original manufacturer documentation confirming the part number CR5ARL-301. Ensure the received components match the specified 300 A rating and in-line form factor. Request test reports or calibration certificates if required for your specific application standards. Confirm compliance with relevant safety certifications such as UL or CE before final acceptance.

Current Sense Transformers Selection Notes

Select this component when a robust, isolated current measurement solution is required for frequencies up to 400 Hz. The in-line design simplifies assembly compared to split-core alternatives. Ensure the system voltage and insulation requirements align with the transformer's specifications. Consider thermal management needs based on the continuous 300 A load and ambient operating conditions.
