The Schneider Electric LC1F4004P7 is a 4-pole contactor from the TeSys F range, rated for 500 A in AC-1 utilisation category at ≤440 V — meaning it is built for switching resistive loads like heaters or furnaces, not motor starting. The 4 NO power pole composition gives you four normally-open main contacts that close when the 230 V AC coil pulls in.
Mounts on a plate — not DIN rail — so panel layout needs to account for the 261 mm width, 206 mm height, and 219 mm depth. Power connections are via bar (30 x 5 mm busbar cross-section) or ring-lug terminals up to 150 mm²; control wiring uses screw clamp terminals accepting 1…4 mm² flexible or solid. Tightening torque is 1.2 N·m on the control circuit and 35 N·m on the power circuit — that 35 N·m figure is a reminder to use a torque wrench on the main lugs, not a hand-tight guess.
Designed to IEC 60947-4-1 and EN 60947-4-1, the contactor standards for low-voltage switchgear. Rated insulation voltage is 1000 V per IEC 60947-4-1, with an impulse withstand voltage of 8 kV. The front face carries IP20 protection with shrouds fitted, conforming to IEC 60529 and VDE 0106.
