ATO-75-B1I-D10

Current Sensors Overview

The LEM ATO-75-B1I-D10 is a split-core current transformer designed for AC current measurement. It features a rated primary current of 75 A and supports frequencies of 50 Hz and 60 Hz. The device provides a current output of 75 mA at the rated primary current (IPr). It has a single pass-through design with a 10 mm aperture, suitable for panel mounting. The unit operates with basic insulation up to 600 V CAT III PD2.

Current Sensors Feature Summary

• Split-core design allows for installation around existing conductors without disconnecting the circuit.
• Provides a dedicated current output signal proportional to the measured primary current.
• Engineered for use in applications requiring basic insulation up to 600 V CAT III PD2.

Current Sensors Applications

• Measurement of AC currents in industrial power systems
• Integration into monitoring devices for electrical distribution panels
• Current sensing in equipment compliant with CAT III PD2 safety standards

Current Sensors Procurement Notes

Verify that the specific part number matches the required output type, as other variants in the series may offer voltage outputs instead of the current output specified for this model. Confirm that the conductor diameter fits within the 10 mm aperture and that the system frequency aligns with the 50/60 Hz specification. Ensure the application environment respects the 600 V CAT III PD2 insulation rating limits.

Current Sensors Selection Notes

Select this component when a non-invasive current measurement solution is required for AC circuits. The choice is driven by the need for a split-core configuration to simplify retrofitting or maintenance. The specific current output characteristic distinguishes it from voltage-output counterparts in the same product family, making it suitable for interfaces expecting a current signal.

Current Sensors Part Context

This component belongs to the LEM ATO1B1I series of current transformers. The series offers various configurations for different current ratings and output types. The ATO-75-B1I-D10 specifically addresses the 75 A rating requirement while providing a current output, distinguishing it from voltage-output models within the same architectural family.

Current Sensors Replacement Considerations

Direct substitutes must match the 75 A rating, split-core topology, and current output specification. Verify compatibility with the 10 mm aperture size and 50/60 Hz frequency range. Cross-reference with other manufacturers' split-core current transducers ensuring identical electrical characteristics and insulation class compliance.
