The LC1F1000N7 is a TeSys F 3-pole contactor rated for 1000 A AC-3 at ≤440 VAC, meaning it handles motor switching up to that current in the standard motor-duty category. For resistive loads (AC-1), the conventional free-air thermal current Ith is 1250 A at 40°C. The 415 VAC control coil operates from 40 to 400 Hz, so a standard 50/60 Hz control transformer works without modification. Motor power capability spans 315 kW at 220-230 V three-phase up to 670 kW at 440 V three-phase. The contactor carries EN 60947-1 and IEC 60947-4-1 certifications, covering the standard for contactors and motor-starters. Rated impulse withstand voltage is 8 kV, overvoltage category III, so it's suitable for fixed-installation distribution panels.
For a BOM freeze or replacement project, the official successor within the TeSys F range should be verified against your specific duty and control voltage.
Mounting is plate-type, not DIN rail — expect to bolt the contactor to a backplate or sub-panel. Dimensions are 438 mm wide, 332 mm high, 238.6 mm deep, so panel layout must account for the footprint and clearance for power bus bars. Power circuit connections use bar-type terminals accepting 3 or 4 cables; control circuit connections are screw clamp terminals accepting 1 to 4 mm² flexible or solid wire. The front face carries IP20 protection with shrouds per IEC 60529 and VDE 0106.
Associated fuse rating is 1400 A gG at ≤440 V for short-circuit coordination. Rated breaking capacity is 8 kA per IEC 60947-4-1, and the rated short-time withstand current (Icw) is 10,000 A for 10 seconds at 40°C — figures needed for selectivity studies in a distribution panel. Power dissipation per pole is 200 W in AC-1 duty, so thermal management inside the enclosure matters — forced ventilation or derating may be needed if multiple contactors are ganged.
