Product Review

This is EKM Metering's 23mm inner diameter, 400A, split-core, current transformer(CT) with 26.6mA output.

It is designed to be used in conjunction with our Omnimeter line of electric meters. This combination provides a highly accurate kWh metering and power monitoring system.

Open-able Split Core CTs are usually much easier to install and can offer a savings in labor costs over Solid Core CTs, depending on the degree of difficulty of the installation.

Built for precision, the Accuracy Class 0.1 CTs are 0.1% accurate for revenue grade submetering.

You will need:
1 of these CTs for 120V American or 230V Foreign 2-wire systems
2 CTs for 120/240V 3-wire or 3-phase 3-wire (3 hots) systems
3 CTs for 3-phase 4-wire (3 hots and a neutral) systems.


Wires coming from the CTs are 2 yards in length. These can be extended but this may affect accuracy.
