TOP 90-S10/SP4

Overview

The LEM TOP 90-S10/SP4 is a non-invasive split-core current transducer designed for precise measurement of alternating currents. It features a rated primary current of 90 A and operates within a frequency range of 50 Hz to 60 Hz. The device utilizes a chassis mounting style for secure installation in industrial environments. This component serves as a reliable interface between high-current circuits and control systems, ensuring accurate signal transmission for monitoring and protection applications.

Feature Summary

Non-invasive split-core design allows for easy installation around existing conductors without circuit interruption.
Chassis mount configuration provides stable mechanical integration into control panels or switchgear.
Optimized for standard power line frequencies to ensure consistent performance in AC applications.

Applications

Industrial motor drive monitoring
Power quality analysis equipment
Switchgear current sensing

Procurement Notes

Verify the specific suffix SP4 against official LEM documentation to confirm pinout and cable length specifications. Ensure the operating environment matches the 50-60 Hz requirement. Cross-reference the chassis mounting dimensions with your enclosure design prior to purchase to guarantee physical compatibility.

Selection Notes

Select this model when a split-core solution is required for retrofitting or temporary monitoring setups. Consider the 90 A rating relative to expected load variations. Evaluate the chassis mount constraint against available panel space compared to PCB-mounted alternatives.

Part Context

This part belongs to LEM's TOP series of current transducers, which are engineered for robust industrial use. The series typically offers high isolation and accuracy suitable for demanding electrical environments. The TOP 90-S10/SP4 represents a specific variant within this lineup tailored for chassis integration.

Replacement Considerations

Consult LEM official cross-reference lists for direct equivalents. Generic substitutes may not match the split-core geometry or chassis mounting requirements. Verify electrical parameters before considering alternative brands.
