Current Sensors Procurement Notes

Verify the specific suffix designation (e.g., /SP3, /SP6) against the required packaging configuration, as standard packaging quantities vary by variant. Confirm that the unidirectional specification aligns with the application's current flow direction requirements before finalizing procurement orders.

Current Sensors Selection Notes

Select this model when high-frequency performance up to 519kHz is required for AC current monitoring. Ensure the 1000A detection range meets system demands. Consider the chassis mount form factor for integration into larger assemblies where space constraints favor modular components over PCB-mounted alternatives.

Current Sensors Part Context

This component belongs to the ARU series, which includes outdoor Rogowski coils designed for electronic measurement in smart grid environments. The series emphasizes robust construction for external applications while maintaining precise current sensing capabilities across varying environmental conditions.

Current Sensors Replacement Considerations

The ARU-B100-D125/SP3 and ARU-B100-D125/SP6 are confirmed variants within the same product family. These parts share identical electrical specifications but differ in standard packaging quantities. Verify the specific suffix requirement based on inventory handling needs.
