The Schneider Electric LC1F150BD22L is a TeSys F series 3-pole contactor rated for 250 A in AC-3 duty (motor switching) at up to 440 V AC. That AC-3 rating governs its real-world motor load capability — it is sized for 75 kW at 380–400 V or 100 HP at 460 V (UL/CSA), so it handles large induction motors in pumps, compressors, and conveyors. The coil is 24 V DC, with an operational range of 0.85–1.1 Uc and a drop-out band of 0.15–0.2 Uc. Built-in auxiliary contacts are 2 NO + 2 NC. It carries IEC 60947-4-1 and EN 60947-4-1 certification for motor-starting duty, plus JIS C8201-4-1. The front face is IP2X with shrouds, acceptable for enclosed panel use where accidental finger contact is the concern.
The LC1F150BD22L mounts on a plate (not DIN rail) — plan for bolted connection. Power circuit connections use bolted bars (2 x 25 x 3 mm) or ring terminals up to 120 mm²; control circuit uses screw clamp terminals accepting 1–4 mm² flexible or solid. Dimensions: 6.4 in (163.5 mm) wide, 6.7 in (171 mm) deep, 11.9 in (301 mm) tall. The 3-pole footprint is standard for the TeSys F frame.
Key ratings and their meaning
Rated breaking capacity is 1200 A per IEC 60947-4-1 — this is the current the contactor can safely interrupt under fault conditions, not the continuous rating. The associated fuse recommendation is 160 A aM or 250 A gG at ≤ 440 V, which sets the short-circuit coordination level. Mechanical durability is 10 million cycles; maximum operating rate is 2400 cycles per hour at 55 °C. Heat dissipation is 4.5 W holding (8 W per pole in AC-3), which matters for enclosure thermal calculations when multiple contactors are ganged. Protective treatment is TH (tropicalized) for humid environments.
