The Schneider Electric TeSys F LC1F78041 is a 4-pole (4 NO) contactor body rated for AC-1 resistive loads at 1600 A per phase (1000 A on the neutral pole) up to 1000 V AC, 40 °C ambient. It's a plate-mount unit — 250 mm deep, 862 mm wide, 434 mm tall — designed for high-current switching in industrial power distribution and heavy resistive heating banks. No coil included; you pair it with a separate TeSys F coil block.
Power circuit torque is 58 N.m. Rated short-time withstand current (Icw) is 6250 A for 10 s — that's the fault-ride-through capability for selective coordination downstream. The making capacity hits 7800 A AC, and the breaking capacity is 6240 A per IEC 60947-4-1. Overvoltage category III and impulse withstand of 8 kV mean it's rated for fixed-installation mains-level transients. Operating altitude goes to 3000 m without derating, which covers most high-altitude plant sites.
The LC1F78041 carries IEC 60947-1, IEC 60947-4-1, EN 60947-1, EN 60947-4-1, and JIS C8201-4-1. That covers the contactor standard for motor starters and switching devices. Protective treatment is TH (tropicalized) for humid environments. Mechanical durability is 5 million cycles — a heavy-duty industrial lifespan for a contactor this size.
