The AC-4 rating at 110 kW (400 V) covers plugging and inching duty, where the contacts open under full locked-rotor current. For resistive loads (AC-1), the contactor is rated 1600 A thermal current (Ith). Control coil draws 2100 VA inrush at 20 °C, with a hold-in range of 0.85–1.1 times the rated coil voltage (400 V AC). Drop-out occurs between 0.2 and 0.4 Uc — useful to know for brownout ride-through planning. Closing time is 40–80 ms; opening takes 130–230 ms. Heat dissipation runs 44 W total, with 60 W per pole in AC-3 and 250 W per pole in AC-1. That matters for enclosure thermal budgeting — a plate-mounted contactor this size (702 mm wide × 434 mm high × 255 mm deep) needs ventilation or forced airflow above 40 °C ambient. This is a direct on-line contactor for heavy motor control in industrial panels — think large pumps, compressors, conveyors, and crushers in the 250–500 kW range at 380–440 V. Plate mounting on a backpanel or chassis; the power circuit uses bolted bar connections accepting up to 100 × 5 mm busbars. Control wiring is screw-clamp, 1–4 mm² flexible or solid. Certified to IEC 60947-1, IEC 60947-4-1, 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. Overvoltage category III. IP20 on the front face with shrouds (IEC 60529, VDE 0106). Protective treatment TH for tropical environments.","metaTitle":"Schneider Electric LC1F780V7 TeSys F Contactor, 780 A AC-3,","metaDescription":"Schneider Electric LC1F780V7 TeSys F contactor. 780 A rated operational current (AC-3), 400 VAC 50/60 Hz coil, 3-pole.
