TeSys F LC1F1000G7 — Heavy-Duty Motor Contactor
The Schneider Electric TeSys F LC1F1000G7 is a 3-pole direct on-line contactor rated for motor control and resistive loads. Its headline rating is 1250 A at ≤440 V AC in AC-3 duty (cites:), which means it can switch a 560 kW motor on a 380–400 V three-phase supply (cites:) — the AC-3 figure governs the real motor-switching capability, not the higher thermal current. The coil is 120 V AC, 40–400 Hz (cites:). This contactor is plate-mounted (cites:), sized for a panel floor or backplate — not a DIN rail. The footprint is 438 mm wide by 332 mm tall by 238.6 mm deep (cites:,), so allocate that space plus clearance for the arc chutes and power bar connections. Power circuit connections are via bar, accepting 3 or 4 cables (cites:).
AC-3 rated operational current is 1250 A at ≤440 V, derated to 1000 A at ambient temperatures below 55 °C (cites:). The conventional free-air thermal current (Ith) is 1250 A at 40 °C (cites:). The short-time withstand current (Icw) is 10 kA for 10 seconds at 40 °C, stepping down to 3 kA for 10 minutes (cites:) — this governs coordination with upstream protection; the associated fuse rating is 1400 A gG at ≤440 V (cites:). Rated breaking capacity is 8 kA per IEC 60947-4-1 (cites:). The contactor carries utilisation categories AC-3 (motor starting, switching under load) and AC-1 (resistive loads) (cites:). The front face achieves IP20 with shrouds fitted, per IEC 60529 and VDE 0106 (cites:). Operating temperature range is -5 to 40 °C (cites:); storage range is -60 to 80 °C (cites:). Permissible ambient air around the device extends to -40 to 60 °C (cites:).
Designed and tested to EN 60947-4-1, IEC 60947-1, IEC 60947-4-1, and EN 60947-1 (cites:). Rated insulation voltage (Ui) is 1000 V per IEC 60947-4-1, 1500 V per VDE 0110 group C (cites:). Impulse withstand voltage (Uimp) is 8 kV (cites:), overvoltage category III (cites:). Protective treatment is TH (tropicalized) (cites:).
