It's a single assembly containing three contactors (KM1 star, KM2 line, KM3 delta) with the interlocking and auxiliary contacts already wired — no field assembly of the delta loop. Its headline rating is 185 A at ≤440 V AC in AC-3 duty, which translates to 160 kW at a 380/400 V supply, 185 kW at 440 V, and 90 kW at 220/230 V. The 185 A figure is the continuous current the main power poles (3 x 3 NO) can carry while switching motor loads. The rated breaking capacity is 1480 A and the rated making capacity is 1850 A, both conforming to IEC 60947-4-1 — so it can interrupt a locked-rotor fault without welding its contacts. This starter mounts to a plate, not a DIN rail. At 525 mm wide, 235 mm deep, and 110 mm high, it's a substantial assembly that needs dedicated space in the enclosure — plan for a backplate footprint of roughly half a metre across. The power connections use M8 bolts and accept lugs or busbars up to 150 mm²; the control circuit uses screw clamp terminals accepting 1 to 4 mm² flexible or solid wire. Torque the power terminals to 18 N·m, control terminals to 1.2 N·m. Heat dissipation runs 18 to 24 W depending on load. At the maximum operating rate of 2400 cycles per hour at 55 °C, that heat adds up — factor it into your enclosure thermal calculation. The contactor withstands 5 Gn vibration when closed (2 Gn when open) and 15 Gn shock when closed — figures that cover most industrial machinery without needing additional damping. The front face carries IP2X protection with shrouds fitted, per IEC 60529. ## Control circuit and auxiliary contacts It draws 805 VA inrush at 50 Hz (970 VA at 60 Hz) at 20 °C. The coil holds in between 0.85 and 1.1 times Uc, and drops out between 0.35 and 0.55 times Uc — a wide dropout margin that reduces the chance of nuisance drop on a sagging line. Opening time is 7 to 15 ms, closing time 20 to 35 ms. Auxiliary contact complement: the KM1 star contactor carries 1 NC + 1 NO, the KM2 line contactor carries 2 NC + 1 NO, and the KM3 delta contactor carries 1 NC + 2 NO. The control circuit wiring accepts flexible cable with or without ferrules, 1 to 4 mm². The starter complies with IEC 60947-4-1, EN 60947-1, EN 60947-4-1, IEC 60947-1, and JIS C8201-4-1. Rated insulation voltage is 1000 V per IEC 60947-4-1 and 1500 V per VDE 0110 group C. Associated fuse protection is 315 A gG or 200 A aM at ≤440 V. No UL or CSA listing appears in the spec record — if your project requires those marks, verify before specifying.","metaTitle":"Schneider Electric TeSys F LC3F185Q7 Star Delta Starter, 185","metaDescription":"TeSys F LC3F185Q7 star delta starter, 185 A rated operational current at ≤440 V AC-3, 160 kW at 400 V.
