The Schneider Electric TeSys F LC1F2100Q7 is a 3-pole contactor rated 2100 A in AC-1 utilisation category, meaning it is sized for heavy resistive loads — heaters, furnaces, large lighting banks — where the current stays near sinusoidal with minimal inrush. The 380 VAC control coil (40-400 Hz) pulls 2200 VA inrush and holds at 36 VA, with drop-out between 0.3 and 0.5 Uc. Plate-mounted, 438 mm wide, 332 mm tall, 238.6 mm deep; power connections are bolted busbar (100 x 5 mm bar, 4 cables).
Do not apply it to motor starting (AC-3) without derating; this contactor is specified for resistive duty. The short-time withstand (Icw) of 10 kA for 10 seconds tells you the fault-withstand capability before the upstream fuse or breaker must clear — the associated fuse recommendation is 2000 A gG at ≤ 440 V. Heat dissipation is 200 W per pole at AC-1 plus 36 W coil hold-in, so panel ventilation or forced cooling is required in a closed enclosure.
The LC1F2100Q7 carries approvals under IEC 60947-4-1, EN 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1. Rated insulation voltage (Ui) is 1000 V per IEC, 1500 V per VDE 0110 Group C. Impulse withstand (Uimp) is 8 kV, overvoltage category III. Protective treatment is TH (tropicalized). These certifications cover the documentation a quality or compliance team needs for panel acceptance in most global jurisdictions.
