Collection: Split Core with CTid

Split-Core CTs with CTid – Simple, Accurate Current Monitoring for Commercial Power Systems

The eGauge ECSXX Series Split-Core CTs are designed for quick, safe, and precise current measurement in commercial and industrial electrical systems. These UL2808-certified current transducers feature CTid auto-detection technology, making them easy to identify and configure during installation especially when CT leads cannot be visually traced.

Ideal for retrofit applications, the split-core design allows the CTs to clamp around live conductors without disconnecting them, reducing downtime and simplifying installation. With a 333mV output, no shorting blocks are needed, ensuring a safe and efficient setup.
