SCT-3000-400

Current Sensors Overview

The Magnelab SCT-3000-400 is a split-core AC current transformer designed for unidirectional current measurement. It features a 400A primary current rating and provides a secondary output of 333mV. The device incorporates an integrated conditioning module to facilitate direct interfacing with monitoring systems. Constructed with a self-locking mechanism, the sensor allows for installation around existing conductors without disconnecting wiring. This configuration supports single-pass-through applications in power distribution environments.

Current Sensors Feature Summary

• Split-core design enables installation on existing electrical wiring without circuit interruption
• Integrated conditioning module provides standardized voltage output for monitoring systems
• Self-locking mechanism ensures secure attachment to the conductor during operation

Current Sensors Applications

• Power distribution monitoring
• Energy management systems
• Industrial equipment current sensing

Current Sensors Procurement Notes

Verify that the specific application requires a unidirectional current sensor, as this model is not suitable for bidirectional flow measurement. Confirm that the system input impedance matches the 333mV output specification. Ensure the primary conductor diameter fits within the split-core aperture limits defined in the official datasheet. Cross-reference the part number against manufacturer documentation to confirm the inclusion of the conditioning module.

Current Sensors Selection Notes

Select this component when a non-intrusive installation method is required for AC current monitoring up to 400A. The integrated conditioning module simplifies signal processing compared to standard transformers requiring external amplification. Consider the physical constraints of the split-core design for retrofitting existing infrastructure where permanent wiring modifications are not feasible or permitted by safety standards.

Current Sensors Part Context

This model belongs to the SCT-3000 series of split-core current transformers from Magnelab. The series is characterized by its ability to snap around conductors, offering flexibility in deployment. Variants within the series differ primarily in current ratings and output specifications, allowing for scalable solutions across various power levels while maintaining consistent installation mechanics.

Current Sensors Replacement Considerations

Direct substitutes must match the 400A rating, 333mV output, and include an integrated conditioning module. Verify compatibility with existing mounting hardware and signal processing circuits. Generic split-core transformers may lack the specific conditioning electronics, requiring additional external components.
