The LC1F185N522L is a 3-pole TeSys F contactor from Schneider Electric, rated 275 A operational current (Ie) at ≤440 V AC in AC-3 duty. That AC-3 rating governs motor switching — it handles 90 kW on a 380–400 V supply, stepping to 100 kW at 415 V and 110 kW at 660–690 V. The 415 V AC 50 Hz coil is a fixed-voltage control circuit, so verify your panel's control transformer matches before wiring; the hold-in power draw is 55 VA at 50 Hz, which matters for transformer sizing in multi-contactor cabinets. For UL/CSA installations, the motor horsepower ratings are 125 hp at 460 V and 150 hp at 575 V — that's the number to hand the inspector if the panel carries a UL label. The contactor meets IEC 60947-4-1 and EN 60947-4-1, so it fits both IEC and North American spec'd lines without a separate part number. The auxiliary contact block comes factory-fitted with 2 NO + 2 NC, which covers most feedback and interlock needs on a motor starter without an add-on module. If you need more, the TeSys F aux contact range clips onto the front without tools.
Deployment context — what it connects to
Plate-mounted, not DIN-rail — expect to bolt it to a backplate or sub-panel. The power circuit uses bolted connections or ring terminals up to 150 mm²; torque the power terminals to 159.3 lbf·in (18 N·m). The control circuit uses screw-clamp terminals accepting 1–4 mm² flexible or solid, torqued to 10.6 lbf·in (1.2 N·m). Overvoltage category III means it's rated for fixed-installation distribution panels, not plug-connected equipment. The IP2X front face with shrouds keeps fingers out but isn't washdown-rated — keep it inside a closed enclosure. Associated fuse ratings are 200 A aM or 315 A gG at ≤440 V — that's the short-circuit protection coordination figure for the motor branch circuit. The rated breaking capacity is 1480 A per IEC 60947-4-1, which is the contactor's own ability to interrupt a fault, not the fuse's job.
