The Schneider Electric TeSys F LC3F330V7 is a pre-wired star delta starter, purpose-built for motor control in the AC-3 utilisation category — meaning it handles starting and stopping of squirrel-cage motors under load, not just resistive switching. Rated 330 A operational current at ≤440 V AC-3, it delivers 280 kW at 380/400 V AC 50/60 Hz and 315 kW at 440 V AC 50/60 Hz. The 400 V AC 50/60 Hz control coil pulls 650 VA inrush at cos φ 0.9, with a 20-second starting time and closing time of 40 to 65 ms.
The associated fuse rating of 500 A gG or 400 A aM at ≤440 V gives the short-circuit protection boundary; pair it with those fuses to keep the starter within its rated breaking capacity of 2640 A and making capacity of 3300 A per IEC 60947-4-1. The 1000 V rated insulation voltage (IEC 60947-4-1) and 1500 V (VDE 0110 group C) mean it's comfortable on 690 V systems if derated, but the AC-3 current is only specified at ≤440 V — don't assume the same 330 A at higher voltages without checking the manufacturer's derating curve. The 3000 m operating altitude without derating means it's fine for most installations short of high-altitude mines or mountain passes.
This is a plate-mount starter — no DIN rail, so plan for a backplate or mounting panel. Dimensions are 725 mm wide, 276 mm deep, and 110 mm high; it's a substantial unit. Power connections use M10 bolts with bar connections accepting 30 x 5 mm busbars or ring terminals up to 240 mm². Control wiring is via screw clamp terminals accepting 1 to 4 mm² flexible or solid wire.
