It integrates three contactors (line, star, delta) with a mechanical interlock in a single assembly, saving panel wiring time and reducing the chance of a mis-wired interlock at startup. Rated for AC-3 utilisation category, it handles 400 A at <= 440 V, which translates to switching squirrel-cage motors up to 375 kW at 440 V. The 400 A AC-3 rating is the key selection number — it governs the motor FLA the starter can handle under starting and jogging duty. The control coil is 220/230 V AC at 50/60 Hz, pulling 1075 VA inrush at cos phi 0.9. Drop-out range is 0.35 to 0.55 Uc, so if your control transformer sags during a line start, this starter drops out predictably — no partial-clutch condition. Mounts on a plate (not DIN rail), so plan for a backplate or sub-panel in the enclosure. Dimensions are 725 mm wide x 180 mm high x 276 mm deep — this is a large assembly; verify the enclosure depth and swing-clearance for the power circuit bolted connections (M10 bolts, bar cross-section 30 x 5 mm). Power circuit connections accept lugs-ring terminals up to 150 mm² or busbars. Control circuit wiring is screw-clamp terminals accepting 1 to 4 mm² flexible or solid. Tightening torque is 35 N.m on the power circuit and 1.2 N.m on the control circuit — a torque wrench on the power lugs is non-negotiable. IP20 front face protection with shrouds (per IEC 60529 and VDE 0106) means finger-safe from the front once shrouded, but the rear and sides are open — keep clearance from live busbars and follow the manufacturer's minimum separation distances. Standards compliance covers IEC 60947-1, IEC 60947-4-1, EN 60947-1, EN 60947-4-1, and JIS C8201-4-1. Rated insulation voltage is 1000 V per IEC 60947-4-1 and 1500 V per VDE 0110 group C.","metaTitle":"TeSys F LC3F400M7A64 Star Delta Starter, 400 A AC-3, 220/230","metaDescription":"Schneider Electric TeSys F LC3F400M7A64 star delta starter. 400 A rated operational current (AC-3) at <=440 V.
