The Schneider Electric LC1F185FE5 is a 3-pole TeSys F contactor with a 115 V AC 50 Hz coil, rated for 275 A operational current in AC-3 duty (motor switching) and built to IEC 60947-4-1. It handles motor loads up to 90 kW at 380–400 V and 110 kW at 500 V AC-3, making it a fit for medium-voltage motor control centers and heavy conveyor or pump drives. Plate-mount construction means it lands on a backplate or sub-panel, not a DIN rail — plan the enclosure layout accordingly.
The AC-1 rating (resistive load) is higher, but for motor duty, stick with the AC-3 figure. Mechanical durability is 10 million cycles, so in a moderate-duty application (one or two operations per minute) it'll outlast the panel. Coil hold-in power is 55 VA at 50 Hz; the inrush is 805 VA — ensure your control transformer can handle that surge on pickup.
Integration notes — plate mount, wiring, environment
Mounts on a plate (not DIN rail). Power circuit terminals accept bar (25 x 3 mm busbar), ring lugs up to 150 mm², or connectors for 150 mm² cable. Control circuit uses screw clamp terminals, 1–4 mm² flexible or solid. Torque: 18 N·m on power, 1.2 N·m on control. Altitude rating is 3000 m without derating. IP2X front face with shrouds — not washdown-rated, so keep it in a cabinet.
