Schneider TeSys D Mechanical & Electrical Interlock for LC1D80/LC1D95 AC – LA9D4002

Schneider TeSys D mechanical and electrical interlock LA9D4002 is designed for reversing and changeover applications using two LC1D80 or LC1D95 AC coil contactors. This robust interlocking accessory ensures safe operation by mechanically and electrically preventing both contactors from closing simultaneously, supporting both 3P and 4P pole configurations. Optimized for industrial motor control and automation panels, it attaches directly to eligible TeSys D-frame (Deca) contactors and meets IEC 60947 standards for reliability.
