The control circuit is 440 V AC 40-400 Hz, with an inrush power of 2100 VA and hold-in consumption of 50 VA. This is a plate-mounted unit, not DIN-rail, so plan for bolted-down integration in a panel or enclosure. The AC-3 rating (450 kW at 1000 V) governs motor switching under starting and running conditions — this contactor handles squirrel-cage motors up to that power. The 1600 A rated operational current at ≤440 V AC-3 sets the thermal capacity for continuous current in motor circuits. The associated fuse recommendation of 1600 A gG or 800 A aM at ≤440 V gives the short-circuit protection boundary. The contactor complies with IEC 60947-1, EN 60947-4-1, EN 60947-1, JIS C8201-4-1, and IEC 60947-4-1. Rated insulation voltage is 1000 V per IEC 60947-4-1 and 1500 V per VDE 0110 group C. Overvoltage category III. Heat dissipation is 44 W total, with 250 W per pole in AC-1 and 60 W per pole in AC-3. ## Physical Integration Dimensions: 17.09 in (434 mm) height, 27.6 in (702 mm) width, 10.04 in (255 mm) depth. Plate-mounted — no DIN-rail clip. Power circuit connections use bolted bars (2 x 100 x 5 mm). Control circuit terminals are screw clamp, accepting 1 to 4 mm² flexible or solid without cable end, or 1 to 2.5 mm² flexible with cable end. Tightening torque: control circuit 1.2 N·m, power circuit 58 N·m.","metaTitle":"LC1F780R7 TeSys F Contactor, 450 kW AC-3, 1600 A, 440 VAC Co","metaDescription":"Schneider Electric TeSys F LC1F780R7 contactor, 450 kW at 1000 V AC-3, 1600 A rated current, 440 VAC 40-400 Hz coil.
