TeSys F 1000 A Contactor — LC1F800KUE
The Schneider Electric LC1F800KUE is a 3-pole contactor from the TeSys F range, rated for 1000 A in AC-3 duty at ≤440 V, making it suitable for switching heavy motor loads such as large pumps, compressors, and conveyors in industrial control panels. The coil accepts 100–250 V AC 50/60 Hz (operational range 85–275 V AC at 55 °C, drop-out 0–60 V AC), with an electronic control circuit that is compatible with PLC 24 V DC inputs per IEC 61131-2 Type 2. The contactor is plate-mounted, with power connections via bolted bars or busbar (60 x 5 mm cross-section) and control wiring through screw-clamp terminals accepting 0.2–2.5 mm² conductors.
The headline rating of 1000 A in AC-3 (motor switching) at ≤440 V defines the maximum motor current this contactor can handle under typical starting and running conditions. The utilisation categories AC-1 (resistive), AC-3 (motor), and AC-4 (inching/plugging) cover the full range of load types. Power dissipation per pole is 120 W in AC-1 and 77 W in AC-3, which must be factored into enclosure thermal management.
This contactor is designed for plate mounting — not DIN-rail — so panel layout must allocate a dedicated mounting surface. Dimensions are 304 mm height, 309 mm width, and 255 mm depth. Power circuit terminals accept bolted bars or busbars up to 60 x 5 mm; control circuit terminals are screw-clamp type for 0.2–2.5 mm² solid or stranded wire. Tightening torque is 58 N·m for power connections and 0.6 N·m for control wiring. The protective treatment (TH) indicates suitability for tropical/humid environments.
The LC1F800KUE is designed to comply with EN/IEC 60947-1 and EN/IEC 60947-4-1, covering low-voltage switchgear and contactor standards. Overvoltage category III is specified, appropriate for fixed-installation industrial panels. The associated fuse rating is 1000 A gG or 800 A aM at ≤440 V. For cross-border procurement, the manufacturer typically provides RoHS and REACH declarations upon request; UL/CSA listings should be verified per specific variant markings.
