• Electrical metering and instrumentation panels

Current Sense Transformers Procurement Notes

Verify the specific datasheet version from CR Magnetics Inc. to confirm electrical tolerances and insulation ratings. Ensure the application environment supports the specified 50-400 Hz frequency range. Check mechanical clearance requirements against the 4.079-inch diameter and 1.098-inch height dimensions before integration into the assembly.

Current Sense Transformers Selection Notes

Select this model when a robust, high-current inline solution is required for frequencies up to 400 Hz. The 300:5 ratio aligns with standard secondary loads. Consider the physical footprint constraints due to the large diameter. Compare against lower current variants if the load exceeds 300 A or requires different mounting styles.

Current Sense Transformers Part Context

This component belongs to the CR6A series of current sense transformers from CR Magnetics Inc. The series provides various current ratings and form factors for power system monitoring. The CR6ARL-301 specifically addresses high-amperage applications requiring reliable magnetic coupling without breaking the primary conductor.

Current Sense Transformers Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Equivalent parts must match the 300:5 ratio, 300 A rating, and similar physical dimensions. Verify that any alternative component meets the same ANSI metering class requirements if applicable.
