1400 A AC-1 contactor, 208 VAC coil — TeSys F frame
The Schneider Electric TeSys F LC1F1400L7 is a 3-pole contactor rated for 1400 A in AC-1 utilisation category, meaning it handles resistive loads (heaters, lighting banks, non-inductive furnaces) at that current. The 208 VAC control coil operates across 40-400 Hz, with a pickup range of 0.85-1.1 Uc and dropout between 0.3-0.5 Uc at 55 °C. This is a plate-mount frame — no DIN-rail clip. At 438 mm wide, 332 mm tall, and 238.6 mm deep, it lands in a bolted panel or enclosure backplate, not a standard cabinet rail. Power circuit connections use busbars up to 100 x 5 mm; control wiring terminates on screw clamp terminals accepting 1-4 mm² flexible or solid.
Lifecycle — end-of-life, sourced to order
The LC1F1400L7 is end-of-life (EOL) per manufacturer lifecycle data.
AC-1 duty and breaking capacity
Rated breaking capacity is 2100 A per IEC 60947-4-1, and short-time withstand (Icw) holds 8000 A for 10 seconds, 6000 A for 30 seconds — enough for coordination with upstream 1600 A gG fuses at ≤440 V. Heat dissipation runs 36 W total (150 W per pole in AC-1), so panel ventilation matters at full load. Average impedance is 0.1 mOhm at 1700 A Ith, 50 Hz.
Certified to EN 60947-1, EN 60947-4-1, IEC 60947-1, JIS C8201-4-1, IEC 60947-4-1, UL 60947-4-1, and CSA C22.2 No 60947-4-1. Rated insulation voltage (Ui) is 1000 V per IEC/UL, 1500 V per VDE 0110 Group C. Impulse withstand (Uimp) is 8 kV, overvoltage category III. Protective treatment is TH for tropical environments.
