Current Sense Transformers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct lead time and availability status. Confirm that the required accuracy class matches the application needs, as commercial grade units typically offer 1% accuracy at 60 Hz. Check for any specific packaging requirements or certification documents such as UL recognition before finalizing the purchase order.

Current Sense Transformers Selection Notes

Select this component when a robust, solid-core solution is required for high-current measurement up to 200 A. Ensure the operating frequency falls within the 50–400 Hz range. Consider the 1.13-inch window size for cable clearance. Verify that the 200:5 ratio aligns with downstream instrumentation inputs. This model is suitable for commercial-grade applications requiring reliable isolation and standard accuracy levels.

Current Sense Transformers Part Context

This part belongs to the CR2 series of current transformers from CR Magnetics Inc. The series is designed for commercial applications requiring precise current sensing. The CR2RL-201 specifically addresses scenarios needing high primary current handling with a standardized secondary output. It complements other sensors in the portfolio by offering a simple, passive solution without active electronics.

Current Sense Transformers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 200:5 ratio, 200 A primary rating, and 1.13-inch window dimensions. Consult the manufacturer directly for equivalent models if exact specifications cannot be met by existing inventory.
