The Schneider Electric LC1F185B722L is a 3-pole TeSys F contactor rated for 275 A in AC-3 duty (motor switching) and 90 kW at 380–400 V AC. The 24 V AC control coil draws 805 VA inrush at 50 Hz and 55 VA holding. It carries 2 NO + 2 NC auxiliary contacts built in.
For resistive loads (AC-1), the same pole set handles higher current; the power dissipation per pole climbs to 25 W in AC-1 versus 12 W in AC-3, so thermal management in the enclosure matters if you run it near the resistive limit. Motor power is listed per voltage: 90 kW at 380–400 V, 100 kW at 415 V and 440 V, 110 kW at 500 V and 660–690 V, and 55 kW at 220–230 V. The UL/CSA horsepower ratings run 50 hp at 200 V up to 150 hp at 575 V — useful if the panel ships to a North American site. The contactor is rated for 1000 V insulation (IEC) and 1500 V (VDE 0110 Group C), with overvoltage category III. That means it's designed for fixed-installation distribution panels, not for surge-prone outdoor feeders. For high-duty applications like frequent conveyor indexing, that rate sets the practical limit.
Mounting is plate-based, not DIN rail — the footprint is 305 mm high, 168.5 mm wide, 181 mm deep. Power connections use bolted bars (2 x 25 x 3 mm) or ring terminals up to 150 mm². Control wiring is screw-clamp, accepting 1–4 mm² flexible or solid. The front face with shrouds carries IP2X protection (finger-safe). Associated fuse sizing: 200 A aM or 315 A gG at ≤ 440 V. The rated breaking capacity is 1480 A per IEC 60947-4-1, which governs its ability to clear a fault without welding.
Designed and certified to EN 60947-1, IEC 60947-4-1, EN 60947-4-1, and JIS C8201-4-1. The TH protective treatment indicates it's tropicalized — suitable for humid or mildly corrosive environments.
