Three normally-open power poles, 1600 A rated operational current at ≤ 440 V AC-3, with a rated breaking capacity of 6240 A per IEC 60947-4-1. The 0.1 mOhm impedance at 1600 A 50 Hz means pole dissipation runs 60 W per pole in AC-3 and 250 W in AC-1 — heat that must be vented in the enclosure. Plate-mounted, 702 mm wide by 434 mm high by 255 mm deep. Power circuit bolted connections accept busbars up to 100 x 5 mm; control circuit screw-clamp terminals take 1 to 4 mm² flexible or solid. Tightening torque is 58 N·m on the power side, 1.2 N·m on control. IP20 front face with shrouds per IEC 60529. ## Deployment context This contactor is sized for heavy motor control in industrial panels — think large pumps, compressors, conveyors, or crushers on 400 V to 1000 V three-phase systems. The 3000 m operating altitude without derating suits high-altitude installations. Overvoltage category III means it is designed for fixed-installation distribution-level transients. The TH protective treatment indicates a tropicalized coating for humidity and corrosive atmospheres. Certified to IEC 60947-4-1, IEC 60947-1, EN 60947-1, EN 60947-4-1, and JIS C8201-4-1. Rated insulation voltage 1000 V per IEC 60947-4-1, 1500 V per VDE 0110 group C. Associated fuse rating 1600 A gG or 800 A aM at ≤ 440 V. Mechanical durability 5 million cycles; maximum operating rate 600 cycles per hour at 55 °C.","metaTitle":"Schneider Electric LC1F780FE7 TeSys F Contactor, 450 kW AC-3","metaDescription":"Schneider Electric LC1F780FE7 TeSys F contactor, 450 kW at 1000 V AC-3, 115 VAC coil.
