The current sensing circuit is isolated from the coil and requires power at Sense V-in and Sense Ground. There are two Sense V-out pins, 0 to 5V and 0 to 10V. They both indicate the current through the main contacts (A2 & A1).

The contactor’s operating coil, and if an auxilary contact is selected too, it needs to be connected with Deutch connector 0857.
Need to be ordered separately and more information is available here https://scn.no/no-components/power-contractors/accessories/0857
