Current Sensors Procurement Notes

Verify the specific suffix /SP4 against the official LEM datasheet to confirm packaging or variant distinctions, as ordering suffixes may alter physical attributes without changing core function. Confirm that the 14-week standard lead time aligns with project schedules, as this component is supplied on order rather than from immediate stock.

Current Sensors Selection Notes

Select this model when measuring unidirectional AC currents up to 1000A with high bandwidth requirements near 519kHz. Ensure the application environment falls within the -40°C to 80°C operating temperature range. Verify that the base-mount module form factor fits the mechanical constraints of the target installation site.

Current Sensors Part Context

This component belongs to the ARU series, which consists of outdoor-rated Rogowski coils intended for electronic measurement in smart grid infrastructure. The series is characterized by its durability for external deployment and integration into modern power distribution monitoring networks.

Current Sensors Replacement Considerations

The ARU-B100-D125 is the base part number for this configuration. Verify if the /SP4 suffix denotes a specific packaging variation or accessory set required for the intended assembly.
