This saved panel space and wiring time compared to building a star-delta pair from individual contactors. The 110 V AC coil is the control voltage that energizes the main power poles. Operating temperature range is -40 to 140 °F (-40 to 60 °C), with derating up to 158 °F (70 °C). Pollution degree 3 means it's designed for an industrial environment with conductive pollution—typical for an open panel or cabinet not in a clean room. ## Obsolete — sourcing path is surplus or broker For a line-down situation where this part is the only approved code on the BOM, the procurement decision is straightforward: issue an RFQ against the LC3D150F7 order code and evaluate availability before considering a redesign to an active star-delta starter from the same or a different family. No drop-in part number is provably pin-compatible from this evidence. ## Fire, flame, and altitude limits The enclosure material carries a V1 flame retardance rating per UL 94, and fire resistance tested to 1562 °F (850 °C) per IEC 60695-2-1. This matters for panel certification—these ratings confirm the part won't propagate a flame or sustain combustion in a fault condition. Operating altitude is rated to 9842.52 ft (3000 m) without derating, so it's fine for most industrial sites but not for high-altitude installations above that. ## Sourcing posture Because the LC3D150F7 is obsolete and there's no official manufacturer replacement, the supply is finite and unreplenished. The right posture is to issue a sourcing RFQ—what you're really buying is a search of the surplus and broker market. If you have a fleet of panels using this part and need spares, now is the time to buy what's left rather than wait for a line-down.","metaTitle":"Schneider LC3D150F7 TeSys star-delta starter, 150A, 110V AC,","metaDescription":"Obsolete LC3D150F7 TeSys D star-delta starter, 150A AC-3, 110V AC coil, 3x3P NO.
