The control circuit runs on 380/400 V AC at 50/60 Hz, with an inrush power of 1075 VA at 40...400 Hz. Operating time is 40...65 ms for closing and 100...170 ms for opening. Mechanical interlocking between the three contactors prevents simultaneous closure of star and delta paths — a standard safety feature for this topology. The rated making capacity is 4000 A and the breaking capacity is 3200 A, both per IEC 60947-4-1. Associated fuse protection is 500 A gG or 400 A aM at ≤440 V — size the upstream protection accordingly. The unit mounts on a plate (not DIN rail), with power connections via M10 bolts or busbars (30 x 5 mm cross-section) and lugs up to 150 mm². Control wiring uses screw clamp terminals accepting 1...4 mm² flexible or solid conductors. ## Where it goes and compliance This is a heavy-duty star delta starter for motor control panels in industrial environments — think pump stations, compressor skids, conveyor drives, and HVAC plant. The plate-mount form factor means it bolts into a sub-panel or backplate, not snapped onto a DIN rail. IP20 front-face protection with shrouds (per IEC 60529 and VDE 0106) keeps fingers out but expects enclosure-level sealing for washdown areas. Standards compliance covers JIS C8201-4-1, IEC 60947-1, IEC 60947-4-1, and their EN equivalents. Rated insulation voltage is 1000 V per IEC 60947-4-1 and 1500 V per VDE 0110 group C. Operating altitude is 3000 m with derating. Protective treatment is TH (tropicalisation) for humid environments.","metaTitle":"Schneider Electric LC3F400Q7A64 TeSys F Star Delta Starter,","metaDescription":"Schneider Electric LC3F400Q7A64 TeSys F star delta starter.
