The Schneider Electric LC1F6304P7 is a TeSys F 4-pole contactor rated for 1000 A in AC-1 utilisation category at ≤440 V, 40 °C — meaning it is sized for switching resistive loads such as large heating banks or furnace elements, not motor starting. The 230 V AC coil (40–400 Hz) draws 1650 VA inrush and 22 VA hold-in. Four normally-open power poles handle the full current path. Mounts on a plate (not DIN rail), with power connections via busbar (60 x 5 mm cross-section) or bolted connection. The IP20 front face with shrouds meets IEC 60529 and VDE 0106 for finger-safe panel integration. Rated breaking capacity is 5040 A per IEC 60947-4-1, and the rated insulation voltage is 1000 V (IEC 60947-4-1) or 1500 V (VDE 0110 Group C). Impulse withstand voltage is 8 kV, overvoltage category III.
The 1000 A AC-1 rating governs the continuous resistive load it can carry. For comparison, a motor load (AC-3) would derate significantly — this contactor is not selected for motor duty. The 4 NO pole configuration means all four poles switch the line; there are no built-in auxiliary contacts, so an external auxiliary block is needed for control-circuit feedback. Associated fuse rating is 1000 A gG or 630 A aM at ≤440 V — the gG (general-purpose) fuse protects against overload and short-circuit; the aM (motor-circuit) fuse is for backup protection only. The 5 Mcycle mechanical durability and 1200 cycles/hour maximum operating rate at 55 °C indicate a heavy-duty switching schedule for process applications. Operating time is 40–80 ms closing, 100–200 ms opening. Heat dissipation is 20 W total (120 W per pole in AC-1).
Physical integration and wiring
Dimensions: 389 mm wide, 304 mm high, 255 mm deep. Plate-mounted — ensure the backplate has clearance for the 255 mm depth plus busbar connections. Power circuit tightening torque is 58 N.m; control circuit is 1.2 N.m. Control wiring accepts 1–4 mm² flexible or solid, with or without ferrules, via screw clamp terminals. Altitude derating begins above 3000 m. The TH protective treatment indicates the contactor is suitable for tropical/humid environments.
