The Schneider Electric LC1F225B6 is a 3-pole TeSys F contactor rated for 315 A in AC-3 duty (motor switching) at ≤ 440 V, with a corresponding motor power of 110 kW at 380–400 V AC 50/60 Hz. That 315 A figure is the operational current under motor load, not the resistive-heating current — for resistive loads (AC-1) the contactor can handle higher current, but the AC-3 number is what governs motor applications. The 24 V AC 60 Hz control coil draws 970 VA inrush and 66 VA hold-in; the drop-out voltage range is 0.35–0.55 Uc, so the coil releases cleanly on a brownout without chattering. The mechanical durability of 10 million cycles gives a long service life in high-cycle applications like conveyor or pump cycling.
Where it fits — panel and deployment context
Plate-mounted (not DIN rail), so plan for a drilled backplate or sub-panel. The footprint is 197 mm high × 168.5 mm wide × 181 mm deep — a substantial frame that needs generous enclosure volume for air circulation around the 18–24 W heat dissipation. Power connections accept bar (32 × 4 mm busbar), ring lugs, or connector for 185 mm² cable; control wiring is screw-clamp terminals for 1–4 mm².
Standards and approvals — what they certify
The rated insulation voltage is 1000 V per IEC 60947-4-1, with a 1500 V rating per VDE 0110 Group C — relevant for 690 V line applications where insulation coordination matters. Overvoltage category III suits fixed-installation distribution panels. The TH protective treatment indicates tropicalization for humid environments.
