Eaton CEMU‑01/03 energy measurement sensor

Eaton CEMU‑01/03 – Current transformer / energy measurement sensor for EMC series

The Eaton CEMU‑01/03 is a compact current sensor for the precise measurement of electrical currents in three-phase systems . It is specifically designed for use with Eaton EMC3P series energy meters (e.g., EMC3P‑D2C1, EMC3P‑P2C1) and provides a reliable interface between the circuits being measured and the energy meter.

The sensor enables the indirect measurement of high currents via current transformer outputs (typically 1 A or 5 A) without having to route the load circuits directly through the energy meter. This makes the CEMU‑01/03 particularly suitable for industrial applications with higher currents and limited space.
