The Schneider Electric TeSys F LC1F400X722L is a 3-pole contactor rated for 500 A in AC-3 duty at ≤ 440 V, meaning it switches motor loads up to that current — in practice, a 200 kW motor at 400 V (AC-3) or a 75 kW motor in the heavier AC-4 category (plugging/reversing). It carries a 550-600 VAC 40-400 Hz coil, so it's built for 575 V control circuits common in North American panels. The contactor is plate-mounted, not DIN-rail, and measures 219 mm deep × 213 mm wide × 375 mm tall — plan for a backplate footprint roughly 8.4 × 14.8 inches.
The 500 A AC-3 rating is the headline number, but the real-world motor capacity depends on voltage: 200 kW at 380-400 V, 220 kW at 415 V, 250 kW at 440 V, 257 kW at 500 V, 280 kW at 660-690 V, and 185 kW at 1000 V. For UL/CSA circuits, it's rated 250 hp at 460 V and 300 hp at 575 V. Mechanical durability is 10 million cycles, so it's built for high-cycle applications like conveyor or pump stations. Heat dissipation runs 14 W holding, 65 W per pole in AC-1 and 42 W per pole in AC-3 — account for that in enclosure thermal calculations.
Mounting, connections, and environment
Mounts on a plate (not DIN rail). Power connections are bolted, accepting two 30 × 5 mm bars or ring terminals up to 150 mm². Control circuit terminals are screw clamp, 1-4 mm² flexible or solid. Tightening torque: 35 N·m on the power side, 1.2 N·m on control. Protective treatment TH (tropicalized) for humid environments.
Compliant with EN/IEC 60947-4-1 and EN/IEC 60947-1, plus JIS C8201-4-1. Rated insulation voltage 1000 V per IEC, 1500 V per VDE 0110 group C. Overvoltage category III. UL/CSA motor power ratings are listed, so it carries North American approvals for 200 V through 575 V systems.
