The control coil accepts 100-250 V AC 50/60 Hz or 100-380 V DC, with a PLC-compatible input per IEC 61131-2 Type 2. Built to EN/IEC 60947-4-1, the contactor is rated for both motor control (AC-3) and resistive loads (AC-1), with a rated breaking capacity of 1480 A and making capacity of 1850 A per the same standard — numbers that tell you it can interrupt a locked-rotor fault without welding contacts. For AC-1 resistive use, the thermal current (Ith) is 275 A at 50 Hz with an average impedance of 0.33 mOhm, so heat dissipation runs 2.2-5.5 W total, or 25 W per pole in AC-1 and 12 W per pole in AC-3. That thermal budget matters in a sealed enclosure. Associated fuse protection: 315 A gG or 200 A aM at ≤440 V. The closing time spans 40-80 ms, opening 6-54 ms — a wide band, so coordination with upstream breakers needs to account for the slowest close. Plate-mounted (not DIN-rail), so plan for a drilled backplate or sub-panel. Dimensions: 174 mm high, 168.5 mm wide, 181 mm deep. Power circuit connections accept bar (25 x 3 mm busbar), ring terminals up to 150 mm², or bolted connection — torque to 18 N·m. Control circuit uses screw-clamp terminals, 0.2-2.5 mm², torque to 0.6 N·m. The protective treatment is TH (tropicalized humidity resistance), and the part carries a standard 3 NO power pole configuration. For environments above 55 °C, derate the operational current — the 275 A figure is at ≤55 °C.","metaTitle":"Schneider Electric LC1F185KUE TeSys F Contactor, 275 A AC-3,","metaDescription":"Schneider Electric LC1F185KUE TeSys F contactor, 275 A rated operational current at 440 V AC-3.
