TeSys Replacement Coil, 72 V AC
The LX1LC0729 is a replacement coil from the Schneider Electric TeSys range, designed for LC1 contactors. Coil resistance measures 24.693 Ohm ±10%, and inductance is 0.107 mH with the magnetic circuit closed. These values let you verify the coil matches the driver output stage — a mismatch here can cause dropout or overheating on the control transformer. Power consumption is 12 to 18 VA sealed at 60 Hz, with an inrush of 170 to 230 VA at 0.55 power factor. The sealed VA is what the control transformer sees continuously, so size the transformer for at least 18 VA per coil plus margin for other loads.
As a world service parts category item, it is stocked for repair and replacement of existing TeSys contactor installations.
