Schneider Electric LAD9R3 Mechanical Interlock

The LAD9R3 is Schneider Electric TeSys kit for assembling 3P reversing contactors LC1D40A-D80A with screw clamp terminals, without electrical interlock. It includes a mechanical interlock (LAD4CM) and a set of power connections (LA9D65A69) to enable safe forward/reverse operation by ensuring only one contactor can be energized at a time. Designed for use with LC1D40A-D80A reversing contactors and intended for screw-terminal terminals, this kit provides the interlock mechanism plus the required power links in a single package to complete a reversing starter configuration. The LAD9R3 is aimed at motor control applications within industrial panels, simplifying the assembly of a 3-pole reversing arrangement by pairing mechanical interlock components with the associated power connection hardware.
