The Schneider Electric LC3F265Q7A64 is a pre-wired TeSys F star delta starter, purpose-built for motor control in the AC-3 utilisation category. It's a three-pole assembly with a mechanical interlock, designed to reduce inrush current during motor startup by first connecting the windings in star configuration, then switching to delta for run. Rated operational current is 265 A at <= 440 V AC, AC-3 duty, which translates to motor power ratings of 110 kW at 220/230 V, 220 kW at 380/400 V and 415 V, and 250 kW at 440 V — all at 50/60 Hz. Control circuit voltage is 380/400 V AC 50/60 Hz, with an operational range of 0.85 to 1.1 Uc and a drop-out window of 0.35 to 0.55 Uc. Inrush power is 650 VA at 40...400 Hz, cos phi 0.9, at 20 °C.
The associated fuse rating is 400 A gG or 315 A aM at <= 440 V, so the upstream protection should be coordinated to those values. The rated breaking capacity is 2120 A, and the rated making capacity is 2650 A, both conforming to IEC 60947-4-1. These numbers tell you the contactor set is built for frequent, heavy-duty cycling — not a once-a-day pump start. Auxiliary contact composition is pre-configured: 1 NC and 1 NO for the KM1 star contactor, 2 NC and 1 NO for the KM2 line contactor, and 1 NC and 2 NO for the KM3 delta contactor. That's a complete interlocking and signalling set built in — no separate aux blocks needed for standard star-delta logic.
Mounting is plate-style — not DIN rail — so plan for a backplate or sub-panel in the enclosure. Dimensions are 625 mm wide, 110 mm high, and 266 mm deep. Power circuit connections are bolted, using M10 bolts, bar (32 x 4 mm busbar cross-section), or lugs/ring terminals up to 240 mm². Control circuit connections are screw clamp terminals accepting 1 to 4 mm² flexible or solid cable. Front face achieves IP20 with shrouds, conforming to IEC 60529 and VDE 0106 — suitable for enclosed panel installation where no one's reaching into live parts. Protective treatment is TH (tropicalised) for humid environments.
Standards compliance includes 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. These certifications cover the regulatory acceptance for most industrial control panels globally.
