The Schneider Electric LC1F6304BD is a 4-pole TeSys F contactor rated for 1000 A AC-1 at ≤440 V — that's resistive loads like heaters or large lighting banks, not motor starting. The 24 V DC coil pulls 1600 W inrush, then holds at 9 W. Closing takes 60–70 ms; opening is faster at 40–50 ms. It's plate-mounted, not DIN-rail, so plan for bolted-down integration in a panel or enclosure.
The 1000 A AC-1 rating governs the real load this contactor can switch continuously. AC-1 is resistive duty — no inrush spike, no arc-stretching inductance. If you're switching motors, the AC-3 rating would be lower; this part is specced for resistive banks. Insulation voltage is 1000 V per IEC 60947-4-1, impulse withstand 8 kV — solid for 400 V and 690 V systems with proper overvoltage category III coordination.
This part is flagged as end-of-life (EOL) phase-out. If you're freezing a new design, look at the TeSys F family's active 4-pole contactors with similar AC-1 current and 24 V DC coil; verify plate-mount compatibility and control circuit voltage limits (0.85–1.1 Uc operational, 0.2–0.35 Uc drop-out at 55 °C).
Plate mount only — no DIN-rail clip. The footprint is 389 mm wide × 304 mm high × 255 mm deep. Power circuit connections are bolted bar or busbar (60 × 5 mm cross-section); control circuit uses screw-clamp terminals accepting 1–4 mm² flexible or solid. Tightening torque: 58 N·m on the power side, 1.2 N·m on the control side. IP20 front face with shrouds per IEC 60529 — fine for enclosed panels, not for washdown environments.
Designed to IEC 60947-4-1, EN 60947-4-1, JIS C8201-4-1, and IEC 60947-1. Overvoltage category III. Protective treatment TH for tropical environments. The associated fuse rating is 1000 A gG at 630 A aM at ≤440 V — use that for short-circuit coordination. Mechanical durability is 5 million cycles; maximum operating rate 1200 cycles/hour at 55 °C.
