The Schneider Electric LC1F1854FE7 is a TeSys F 4-pole contactor rated for 275 A at ≤440 V in AC-1 duty (resistive loads). The 115 V AC coil accepts 40-400 Hz control supply, with an inrush of 1070 VA and a hold-in draw of 9.9 VA. This is a plate-mount part — no DIN-rail clip — sized for bolting into a panel or enclosure backplate.
The 275 A AC-1 rating governs resistive loads like heaters or lighting banks. For motor duty (AC-3), the contactor will carry less — the spec table doesn't list an AC-3 current, so size up if you're switching induction motors. The 4 NO pole arrangement means all four poles close together; no built-in auxiliary contacts, so add a side-mount block if you need feedback. The 115 V AC coil operates between 0.85 and 1.1 Uc at 55 °C and drops out between 0.35 and 0.55 Uc — standard for this class.
Integration notes
Plate-mount only — no DIN-rail adapter. Power circuit terminals accept bar (25 x 3 mm busbar), ring lugs, or connectors up to 150 mm² cable. Control circuit uses screw clamp terminals for 1-4 mm² flexible or solid wire. Tightening torque: 1.2 N·m on control, 18 N·m on power. The front face with shrouds achieves IP2X per IEC 60529 and VDE 0106.
