The LAD91218A is a star delta connection kit from the Schneider Electric TeSys Deca range, designed for 3-pole configurations. It mounts downstream or upstream of LC1D09-32 snap-in contactors, providing the interconnections needed for star-delta motor starting. This kit is rated for an operating ambient temperature of -25 to 60 °C, matching the thermal envelope of the contactors it pairs with. Storage range extends from -60 to 80 °C.
The kit is designed to EN/IEC 60947-4-1 and GB/T 14048.4, the governing standards for contactors and motor-starters. These cover the dielectric, thermal, and mechanical endurance requirements for industrial motor control.
