The Schneider Electric LC3F185E7A64 is a pre-wired star delta starter from the TeSys F range, designed for motor control in AC-3 utilisation category. It handles a rated operational current of 185 A at <= 440 V AC, switching motors up to 160 kW at 380/400 V AC 50/60 Hz.
For a 160 kW motor at 400 V, the full-load current typically sits around 280-300 A, so this starter is sized for the line current the motor draws during delta run, not the star-start inrush. The rated making capacity of 1850 A and breaking capacity of 1480 A, both per IEC 60947-4-1, confirm it can handle the transient when closing onto a stalled rotor and interrupt a locked-rotor fault without welding contacts. The control circuit voltage limits are 0.85...1.1 Uc for pickup and 0.35...0.55 Uc for dropout at 50/60 Hz below 55 °C. That means the 48 V coil will pick up reliably at 40.8 V and drop out between 16.8 and 26.4 V. The inrush power is 805 VA at 50 Hz (cos phi 0.3) and 970 VA at 60 Hz — factor that into your control transformer sizing if you're feeding multiple starters from one 48 V bus. The auxiliary contact configuration is built in: 1 NC + 1 NO on the star contactor (KM1), 2 NC + 1 NO on the line contactor (KM2), and 1 NC + 2 NO on the delta contactor (KM3). That covers the interlocking and status feedback for a standard star-delta sequence without adding external aux blocks.
This is a plate-mount starter, not DIN-rail. The dimensions are 525 mm wide by 110 mm high by 235 mm deep, so it needs a backplate or mounting panel with clearance for the M8 bolted power connections. Power circuit lugs accept up to 150 mm² cable or busbar (25 x 3 mm cross-section). Control circuit wiring uses screw clamp terminals for 1 to 4 mm² flexible or solid wire. Tightening torque is 18 N.m on the power circuit and 1.2 N.m on the control circuit. The protective treatment is TH (tropicalized), so it handles humidity better than a standard untreated contactor.
