The Schneider Electric TeSys F LC1F2100M7 is a 3-pole contactor rated for 2100 A in AC-1 duty (resistive loads) at up to 40 °C ambient. That AC-1 rating — 2100 A conventional free-air thermal current — means it's sized for heavy resistive switching, like large heating banks or furnace loads, not motor starting. The control circuit runs on 220 VAC 40-400 Hz, with a pickup range of 0.85 to 1.1 times nominal and dropout at 0.3 to 0.5 times nominal at 55 °C.
The 2100 A AC-1 rating is the headline number, but pay attention to the breaking capacity: 3150 A per IEC 60947-4-1. That's the current it can safely interrupt under fault conditions. The short-time withstand current (Icw) is 10 kA for 10 seconds at 40 °C — useful for coordination studies if you're sizing upstream protection. Associated fuse recommendation is 2000 A gG at up to 440 V. Plate-mounted, dimensions 438 mm wide x 332 mm high x 238.6 mm deep — plan your enclosure layout accordingly. Heat dissipation is 36 W total, 200 W per pole in AC-1 duty, so ventilation matters in a sealed panel.
The LC1F2100M7 carries compliance with IEC 60947-1, IEC 60947-4-1, EN 60947-1, EN 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1. Rated insulation voltage is 1000 V per IEC 60947-4-1, 1500 V per VDE 0110 Group C, and 1000 V per UL 60947-4-1. Impulse withstand voltage is 8 kV, overvoltage category III. Protective treatment is TH (tropicalized).
