The Schneider Electric LC3F265E7 is a pre-wired TeSys F star-delta starter, built as a single assembly for reduced-voltage starting of three-phase induction motors. It integrates three contactors — line, star, and delta — in one package, saving the panel builder the wiring and interlocking work of assembling discrete components. Rated for AC-3 duty (squirrel-cage motor switching), it handles motor power from 110 kW at 220/230 V AC up to 250 kW at 440 V AC, all at 50/60 Hz. The 48 V AC 50/60 Hz control coil draws 650 VA inrush at 20 °C, and the assembly is rated for 10 million mechanical cycles. The star-delta topology means the motor starts in star configuration to limit inrush current, then transitions to delta for full-load running. The LC3F265E7's internal contactor set handles this sequence automatically, with a starting time of 20 s and a closing time of 40...65 ms.
The 2650 A making capacity and 2120 A breaking capacity (both per IEC 60947-4-1) tell you it can handle the inrush and fault-clearing demands of motors up to its rated kW range without welding contacts or failing to interrupt. The 3 x 3P pole configuration means three power poles, each with three normally-open contacts — standard for a three-phase star-delta circuit. The auxiliary contact complement (1 NC + 1 NO on the star contactor, 2 NC + 1 NO on line, 1 NC + 2 NO on delta) provides feedback and interlocking signals without needing add-on blocks. Rated insulation voltage is 1000 V per IEC 60947-4-1 and 1500 V per VDE 0110 group C, so it's comfortable on 400 V and 690 V systems with margin.
Where this class of part is used
Star-delta starters are the standard reduced-voltage starting method for three-phase induction motors above about 5 kW, where direct-on-line starting would cause excessive voltage drop on the supply. Common loads include pumps, fans, compressors, and conveyors that don't require variable speed or soft-start profiles. The LC3F265E7 is sized for motors in the 110–250 kW range, which typically serve medium-to-large industrial machinery — think 200 HP class pump sets, large ventilation fans, or main drive motors on production lines. The plate mounting means it bolts to a back panel, not a DIN rail, so plan for the 625 mm width × 266 mm depth × 110 mm height footprint in your enclosure layout.
For a BOM line requiring this exact order code, the supply posture is quoted-to-order against an RFQ. The 48 V AC control voltage is less common than 110 V or 230 V AC coils, so verify the control transformer tap before specifying. No official successor has been published; the TeSys F series remains the current generation for this frame size.
