This is a big-frame, plate-mounted part — 338 mm tall, 309 mm wide, 255 mm deep — built for heavy switching in industrial power distribution and large resistive heating banks. The 1260 A Ith and 1260 A Ie in AC-1 confirm this contactor is sized for resistive loads. Average impedance is 0.12 mOhm per pole. The LC1F1250UD is at end-of-life (EOL) status. ## Integration notes Mounts to a plate (not DIN rail) — the 338 x 309 mm footprint and 58 N.m power-circuit torque call for a steel backplate, not a plastic enclosure. Power connections are bar terminals sized for 100 x 5 mm busbars; control wiring takes screw-clamp terminals accepting 1 to 4 mm² flexible or solid. The coil holds at 250 VDC nominal, with an operational range of 0.85 to 1.1 Uc and drop-out between 0.2 and 0.35 Uc. Heat dissipation is 9 W holding, 120 W per pole under load — plan ventilation or derating if the panel runs above 40 °C. Designed to IEC 60947-4-1 and IEC 60947-1, with EN 60947-1 and JIS C8201-4-1 equivalents. Rated insulation voltage is 1000 V per IEC 60947-4-1 (1500 V per VDE 0110 group C), with an 8 kV impulse withstand. Protective treatment is TH (tropicalised) for humid environments.","metaTitle":"Schneider LC1F1250UD TeSys F Contactor, 1260 A AC-1, 250 VDC","metaDescription":"Schneider Electric LC1F1250UD TeSys F contactor. 1260 A AC-1, 250 VDC coil.
