For resistive loads (AC-1) the thermal current Ith is also 500 A, but the real-world limit for motor starting is the AC-3 number. The 400 A AC-3 derating at <55 °C means the full 500 A is available only below that ambient; above it, the contactor must be downrated per the thermal curve. Control voltage is 100–250 V AC 50/60 Hz or 100–380 V DC, with operational limits of 85–275 V AC and 85–418 V DC at 55 °C. Drop-out thresholds are 0–60 V AC and 0–45 V DC — useful for brownout ride-through planning. The electronic DC control circuit is PLC-compatible per IEC 61131-2 Type 2, with on-state at 11–30 V and off-state below 5 V. Mounting is plate-only — no DIN-rail clip on this frame size. The 219 mm depth and 213 mm width mean it needs a backplate with generous clearance for the 30 x 5 mm busbar connections and the 150 mm² lug-ring terminals on the power circuit. This part is in EOL hot stage — end-of-life active, meaning the manufacturer has announced discontinuation and the last-time-buy window is either closing or closed. ## Deployment context This contactor is sized for motor control in heavy industrial panels — conveyors, pumps, compressors, and other three-phase loads up to 500 A AC-3. The plate-mount form factor and bar/lug terminals suit fixed-installation switchgear rather than modular DIN-rail enclosures. The TH protective treatment indicates tropicalization for humid or corrosive environments. Rated breaking capacity is 3200 A and making capacity 4000 A per IEC 60947-4-1, so it coordinates with upstream 500 A gG or 400 A aM fuses at ≤440 V.","metaTitle":"Schneider Electric LC1F400KUE TeSys F Contactor, 500 A AC-3,","metaDescription":"Schneider Electric LC1F400KUE TeSys F contactor, 500 A AC-3 at ≤440 V, 3-pole.
