The Schneider Electric LC1F400VD is a TeSys F three-pole contactor with a 400 VDC coil, rated for motor and resistive loads across AC-1, AC-3, and AC-4 utilisation categories. It switches up to 500 A in AC-3 duty at 440 V, translating to 200 kW at 400 V or 220 kW at 415 V — a heavy-duty machine-tool or pump contactor for a 200 kW class motor. The 400 VDC coil is uncommon; most TeSys F contactors run AC or lower DC coils, so verify your control voltage matches before committing the BOM line.
This part carries an EOL hot lifecycle marker. The manufacturer has flagged end-of-life but the part is still in the supply chain for last-time buys.
The 500 A AC-3 rating (at 440 V, 55 °C) is the headline number for motor switching — it governs the contactor's ability to make and break locked-rotor current. The AC-4 rating (75 kW at 400 V) matters if you need to reverse or plug the motor in-cycle, where the contactor must interrupt full-load current repeatedly.
Plate-mount only — no DIN-rail clip on this frame size. The power circuit uses bolted connections or ring lugs (up to 150 mm² cable or 30 x 5 mm busbar). Control circuit terminals are screw clamp, accepting 1 to 4 mm² flexible or solid. Tightening torque for the power circuit is 35 N.m — substantial, so a torque wrench is expected. IP20 with shrouds on the front face, so it needs a panel or enclosure to meet touch-safe requirements.
Certified to IEC 60947-4-1, EN 60947-4-1, and JIS C8201-4-1. Rated insulation voltage 1000 V per IEC 60947-4-1, overvoltage category III. The 400 VDC coil has operational limits of 0.85 to 1.1 Uc and drop-out at 0.2 to 0.35 Uc — ensure your DC supply stays within that window, especially under brownout conditions.
