The Schneider Electric TeSys F LC1F1000RD is a 3-pole (3 NO) contactor rated for heavy motor and resistive loads, with a conventional free air thermal current (Ith) of 1250 A at 40 °C and a rated operational current (Ie) of 1000 A in AC-3 duty at ≤440 V AC. That AC-3 rating is the figure that governs motor switching — it means the contactor handles the high inrush of squirrel-cage motors during starting and breaking, not just steady-state resistive current. The coil is DC standard at 440 V DC, so verify your control voltage matches before wiring.
Motor Power and Breaking Capacity
The LC1F1000RD covers a wide motor power range: 315 kW at 220–230 V three-phase, 560 kW at 380–400 V, 630 kW at 415 V, and 670 kW at 440 V. The rated breaking capacity is 8 kA per IEC 60947-4-1, and the rated short-time withstand current (Icw) holds 10 kA for 10 seconds at 40 °C — figures that matter for coordination with upstream protective devices. The associated fuse recommendation is 1400 A gG at ≤440 V.
This part is in end-of-life (EOL) phase-out status.
Mounting is plate-based — not DIN-rail snap-on — so plan for bolt-down integration in the panel. Dimensions are 438 mm wide, 332 mm high, and 238.6 mm deep. The IP20 front face with shrouds (per IEC 60529 and VDE 0106) means finger-safe from the front but not sealed against moisture; keep it in a clean, dry enclosure. Power circuit connections use bar-type terminals for 3 or 4 cables; control circuit uses screw clamp terminals accepting 1–4 mm² flexible or solid wire.
Certified to EN/IEC 60947-1 and 60947-4-1. Rated insulation voltage (Ui) is 1000 V per IEC 60947-4-1, 1500 V per VDE 0110 Group C. Impulse withstand voltage (Uimp) is 8 kV, overvoltage category III. The TH protective treatment indicates tropicalization for humid environments.
