The DC control circuit operates at 250 V nominal, with a pick-up range of 0.85–1.1 Uc and drop-out between 0.2–0.35 Uc at 55 °C. Closing time runs 50–60 ms, opening 45–60 ms — fast enough for most sequencing but not for high-speed reversing without interlocking. The headline 500 A AC-3 rating governs motor switching duty — that is the current the contactor can make and break across the motor inrush and running cycle. At 400 V that translates to 200 kW motor power; at 690 V it reaches 280 kW. The AC-1 rating (resistive load) is higher, but for motor control the AC-3 figure is the one that decides the BOM line. The associated fuse recommendation is 400 A aM or 500 A gG at ≤440 V — coordinate the upstream protection accordingly. Heat dissipation sits at 6 W holding, 65 W per pole in AC-1 and 42 W per pole in AC-3 — factor that into enclosure thermal calculations. This contactor mounts to a plate (not DIN rail), so plan for a backplate or sub-panel in the enclosure. Dimensions are 8.6 in deep by 8.4 in wide by 8.1 in tall — allow clearance for the power circuit bar connections (2 x 30 x 5 mm bar or ring terminals up to 150 mm²). Standards compliance covers IEC 60947-1, IEC 60947-4-1, EN 60947-4-1, EN 60947-1, and JIS C8201-4-1 — accepted across European, UKCA, and Japanese regulatory frameworks. Rated insulation voltage is 1000 V (IEC) and 1500 V (VDE 0110 group C), with overvoltage category III. If a direct drop-in replacement from the TeSys F family exists, it would need to be verified against the specific control voltage (250 VDC) and mounting footprint — the DC coil variant narrows the cross-reference options. For now, sourcing is limited to what the independent channel holds. We can quote this part to order against an RFQ.","metaTitle":"Schneider LC1F400UD TeSys F Contactor, 500 A AC-3, 250 VDC C","metaDescription":"Schneider Electric LC1F400UD TeSys F contactor. 500 A rated operational current (AC-3), 200 kW at 400 V. 250 VDC control coil.
