The Schneider Electric LE3D12P7A04 is an enclosed star-delta starter from the TeSys LE range, designed for standard motor starting applications. The unit is rated for 12 A in AC-3 utilisation category, which is the standard duty for starting squirrel-cage induction motors: switching 12 A under full load, with the inrush handled by the contactors inside. No pushbuttons are included on the enclosure — control is wired externally.
Motor power and application fit
This starter is rated for 11 kW at 380/400 V AC, 11 kW at 415 V AC, and 11 kW at 440 V AC, all at 50/60 Hz. On a 220 V AC supply it is rated for 5.5 kW. The AC-3 rating of 12 A is the key selection parameter — it tells you the continuous motor current the starter can handle during running, not the brief starting surge. For a 12 A AC-3 rating, expect to pair this with a motor drawing around 12 A full-load current. The device composition requires a thermal overload relay ordered separately, plus the star-delta contactors and mechanical interlock are included in the assembly.
