The Schneider Electric LC3F115Q7 is a frame star-delta starter from the LC3-F series, with a coil rated for 380-400 V AC. It is designed for reduced-voltage starting of three-phase induction motors — the star-delta method limits inrush current during the transition from start to run, which is a standard approach for motor control panels where the supply can handle the transition surge.
Sourcing reality — obsolete part, no factory substitute
This part is officially obsolete. No factory-specified successor exists. Submit an RFQ for availability. The coil voltage (380-400 V AC) is a key fit parameter for any replacement search — if you are evaluating a substitute from the LC3-F line or another manufacturer's star-delta starter, matching this coil range is the first gate. The frame size (LC3-F) also governs the contactor and thermal overload mounting footprint.
