The Schneider Electric LC1F7804V7 is a TeSys F 4-pole contactor rated for 1600 A in AC-1 duty (resistive load) at ≤440 V, making it a high-current switching component for heavy resistive loads like large heating banks or furnace circuits. The 400 V AC control coil draws 2100 VA inrush and 50 VA hold-in, with a drop-out threshold between 0.2 and 0.4 Uc — something to verify if the control supply dips during a brownout. It mounts to a plate, not a DIN rail, so factor in the 862 mm width and 434 mm height when laying out the panel.
The 1600 A rated operational current is specific to AC-1 utilisation category — resistive loads only. Do not apply this contactor to motor (AC-3) or inductive loads without derating; the associated fuse recommendation of 1600 A gG or 800 A aM at ≤440 V gives the upstream protection boundary. The 1000 V rated insulation voltage (IEC 60947-4-1) and 8 kV impulse withstand voltage place it in overvoltage category III, suitable for fixed industrial installations. The 44 W heat dissipation (250 W per pole) needs to be vented in the enclosure — a sealed box with this contactor running near its rating will cook adjacent components.
Plate-mounted with bolted power connections accepting busbars up to 100 x 5 mm. Control circuit uses screw-clamp terminals accepting 1 to 4 mm² flexible or solid wire. Power circuit torque is 58 N.m — a calibrated torque wrench is mandatory here; undertightening creates a hot joint. Operating altitude is 3000 m without derating; storage temperature range is -60 to 80 °C.
