Schneider LAD9V2 TeSys Deca Mechanical Interlock LC1D

The Schneider Electric LAD9V2 is a mechanical interlock for TeSys D-LINE contactors, designed to ensure safe directional control and source changeover switching in 3-pole and 4-pole configurations. It prevents simultaneous energization of two contactors, enabling reliable reversing and transfer switching applications. Compatible with the full TeSys D contactor range up to LC1D38 and LC1DT40.
