The Schneider Electric LC1F1154Q7 is a TeSys F 4-pole contactor rated for 200 A in AC-1 utilisation category (resistive loads) at ≤ 440 V, with a 380 V AC 40-400 Hz coil. This is a heavy-duty power contactor for switching resistive heating elements, lighting banks, or transformer primaries where the AC-1 rating governs — not for motor starting (that would be AC-3). The 4 NO power pole configuration and 200 A continuous current mean it handles substantial resistive loads without derating up to 40 °C ambient.
Mounts to a plate — not DIN rail, so factor in panel drilling and hardware. The power circuit uses bolted connections; terminals accept bar (20 x 3 mm busbar), lugs (1 x 95 mm² cable), or connectors (1 x 95 mm²). Control circuit uses screw clamp terminals accepting 1-4 mm² flexible or solid. Tightening torque: 10 N·m on power circuit, 1.2 N·m on control circuit. Dimensions: 200.5 mm wide, 162 mm high, 171 mm deep. IP2X front face with shrouds — basic finger protection, not washdown-rated.
Rated breaking capacity is 920 A per IEC 60947-4-1. Mechanical durability is 10 million cycles. Operating time: 35 ms closing, 130 ms opening at rated control voltage. Heat dissipation is 5.9-7.2 W total, with 15 W per pole in AC-1 duty. Average impedance is 0.37 mΩ at Ith 200 A, 50 Hz. Inrush power consumption is 770 VA, hold-in is 8.1 VA at 20 °C. Control voltage limits: pick-up 0.85-1.1 Uc, drop-out 0.2-0.55 Uc at 55 °C. Rated insulation voltage is 1000 V per IEC 60947-4-1, 1500 V per VDE 0110 group C. Impulse withstand voltage is 8 kV. Operating altitude: 3000 m without derating. Ambient temperature range: -40 to 60 °C operating, -60 to 80 °C storage. Overvoltage category III. Protective treatment TH. Associated fuse ratings: 125 A aM or 200 A gG at ≤ 440 V. Maximum operating rate: 2400 cycles/hour at 55 °C.
