TeSys F Contactor, 275 A AC-3 — End-of-Life Sourcing Note
The Schneider Electric LC1F185F722L is a TeSys F 3-pole contactor rated for 275 A at ≤ 440 V AC in AC-3 duty, meaning it switches motor loads up to that current — typically a 90 kW motor at 400 V or 125 hp at 460 V per UL/CSA. The 110 V AC 50/60 Hz control coil draws 970 VA inrush (60 Hz) and 55 VA holding.
The 275 A AC-3 rating governs motor switching; for resistive loads (AC-1), the contactor can handle higher currents — the power dissipation per pole is 12 W in AC-3 and 25 W in AC-1. The 110 V AC coil operates between 0.85 and 1.1 Uc (93.5–121 V) and drops out between 0.35 and 0.55 Uc (38.5–60.5 V). The contactor carries 2 NO + 2 NC auxiliary contacts built in.
Compliant with IEC 60947-1, IEC 60947-4-1, EN 60947-1, EN 60947-4-1, and JIS C8201-4-1. Rated insulation voltage is 1000 V per IEC 60947-4-1 and 1500 V per VDE 0110 group C. Overvoltage category III. The front face with shrouds provides IP2X protection per IEC 60529 and VDE 0106. Protective treatment is TH for tropical environments.
Plate-mounted (not DIN rail). Power circuit connections use bolted bars (2 bars 25 x 3 mm) or ring terminals up to 150 mm². Control circuit terminals accept 1–4 mm² solid or flexible wire (1–2.5 mm² with cable end). Tightening torque is 159.3 lbf·in (18 N·m) for power and 10.6 lbf·in (1.2 N·m) for control. Dimensions: 12.008 in (305 mm) height, 6.6 in (168.5 mm) width, 7.1 in (181 mm) depth.
The LC1F185F722L is classified as end-of-life (EOL) by the manufacturer. For BOM lines requiring this exact code, sourcing is through independent channels; we can quote availability and pricing against an RFQ. The associated fuse rating is 200 A aM or 315 A gG at ≤ 440 V.
