The LC1F150KUE is a 3-pole contactor from the TeSys F series, rated for 250 A in AC-3 duty at ≤440 V. AC-3 is the standard utilisation category for squirrel-cage motor starting. The control circuit accepts 100-250 V AC 50/60 Hz or 100-380 V DC, with a wide operational range: 85-275 V AC and 85-418 V DC at 55 °C. Drop-out thresholds are 0-60 V AC and 0-45 V DC, giving clean release margins. The coil is electronic, compatible with PLC 24 V DC inputs per IEC 61131-2 Type 2, though the coil voltage itself is the higher range — the PLC compatibility refers to the input interface, not the coil drive. Rated breaking capacity is 1200 A per IEC 60947-4-1, and making capacity is 1500 A. The associated fuse recommendation is 315 A gG or 200 A aM at ≤440 V.
Mounts on a plate, not a DIN rail. The power circuit uses bolted connections accepting bars, busbars (25 x 3 mm), lugs, or connectors up to 120 mm². Control wiring is via screw-clamp terminals for 0.2-2.5 mm² solid or flexible wire. Tightening torque is 18 N·m on the power side, 0.6 N·m on control — a torque wrench is expected for the power terminals. Dimensions are 171 mm deep, 163.5 mm wide, 170 mm tall.
