ACUCT-125R-400:333

Current Sense Transformers Overview

The ACUCT-125R-400:333 is a split-core current transformer designed for non-invasive measurement of high-current alternating current circuits. It features a 400A primary current rating and a 1.25-inch aperture to accommodate conductors without circuit interruption. The device provides a 333mV output signal with a 2.5-meter lead length, facilitating integration into monitoring systems.

Current Sense Transformers Feature Summary

• Non-invasive split-core design allows installation around existing busbars or cables without disconnecting power
• High accuracy construction ensures reliable data acquisition for industrial current sensing applications
• Integrated 2.5-meter leads provide flexible connection options to downstream signal conditioning equipment

Current Sense Transformers Applications

• Industrial energy monitoring systems requiring real-time current data
• Building automation and HVAC control panels for load management
• Power quality analysis equipment for harmonic distortion assessment

Current Sense Transformers Procurement Notes

Verify the specific model suffix matches the required aperture size and output voltage. Confirm that the 400A rating aligns with the maximum expected load current in the target application. Ensure the 333mV output impedance is compatible with the input requirements of the connected metering or PLC module before finalizing the purchase order.

Current Sense Transformers Selection Notes

Select this component when a non-invasive solution is required for measuring currents up to 400A. The 1.25-inch aperture must be sufficient for the conductor diameter. Consider the 333mV output level against the sensitivity of the receiving instrumentation. This model is suitable for fixed installations where periodic maintenance access is limited.

Current Sense Transformers Part Context

This current transformer belongs to the ACUCT series from Automation Components, Inc., which specializes in field components for industrial automation. The series offers various aperture sizes and current ratings to suit different busbar configurations. The split-core format distinguishes it from solid-core transformers, offering easier retrofitting capabilities.
