The Schneider Electric VW3A68E8862 is a TRANSFO COURANT T5 current transformer, part of the Altivar drive accessory family. Its function is to provide isolated current measurement for the drive's control electronics, typically used on the output phase of a variable frequency drive to monitor motor current for overload protection or feedback loops.
The description TRANSFO COURANT T5 identifies it as a specific current transformer variant within the Altivar T5 series. As a current transformer, its primary rating is the transformation ratio and the burden it presents to the drive's analog input.
Mounts on the output conductors of the Altivar drive, typically inside the enclosure. The transformer has a window for the phase cable; no electrical connection to the primary side is needed.
