Current Sense Transformers Procurement Notes

Verify the specific datasheet version for precise burden resistance and accuracy class details before integration. Confirm that the 1200 A primary rating aligns with the system's maximum expected load. Ensure physical clearance accommodates the 119.38 mm diameter and 27.94 mm height. Check termination compatibility for the provided wire leads. Validate frequency range suitability for the target application spectrum.

Current Sense Transformers Selection Notes

Select this component when a non-invasive solution for currents up to 1200 A is required. The wide frequency range supports both standard utility frequencies and higher harmonic environments. The free-hanging form factor allows flexible installation within existing busbar or cable arrangements. Consider the physical size constraints relative to the available mounting space in the enclosure or panel.

Current Sense Transformers Part Context

This part belongs to the CR Magnetics current transformer series, which provides various ratings for industrial sensing needs. The CR7ARL-122 specifically addresses high-amperage applications where isolation and safety are critical. It complements lower-rated models in the lineup by offering robust performance for heavy-duty power systems.

Current Sense Transformers Replacement Considerations

Direct substitutes may include other CR Magnetics models with similar 1200 A ratings, such as the CR7ARL-152 or CR7ARL-162, depending on specific current requirements. Verify dimensional compatibility and terminal styles when considering alternatives from different manufacturers.
