The Schneider Electric LC1F2100MD is a 3-pole contactor from the TeSys F range, rated for 2100 A in AC-1 utilisation category (resistive loads) at 40 °C. The 220 V DC coil draws 10 W holding power and operates within 0.85–1.1 Uc at 55 °C, with drop-out between 0.2–0.35 Uc. This is a heavy-duty plate-mounted contactor — 438 mm wide, 332 mm high, 238.6 mm deep — sized for main power switching in industrial panels where resistive heating banks, large transformers, or high-current distribution need reliable make/break.
Rated breaking capacity is 3150 A per IEC 60947-4-1, and short-time withstand (Icw) reaches 10 kA for 10 s at 40 °C, tapering to 3 kA for 10 min. The associated fuse recommendation is 2000 A gG at ≤ 440 V. Insulation voltage is rated 1000 V (IEC) / 1500 V (VDE group C), with impulse withstand of 8 kV. The contactor carries approvals under UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1 — accepted in North American, European, and Japanese panels. Power circuit connections use bar or bolted busbars up to 100 x 5 mm cross-section; control circuit terminals accept 1–4 mm² flexible or solid wire.
