The LC3D090AV7 is a TeSys D star delta starter from Schneider Electric, designed for motor control in AC-3 duty. It switches 9 A at the coil voltage of 400 V AC, with three normally open power poles per phase (3 x 3P).
Schneider has marked the LC3D090AV7 as Obsolete. There is no official successor order code listed, so the only sourcing channel is the surplus and broker market. We can source it to order against an RFQ.
Rated for AC-3 utilization category, meaning it's built for switching squirrel-cage motors under normal starting and running conditions — not resistive loads. The 9 A rating is the AC-3 motor current; for a 400 V supply this typically covers motors up to about 4 kW, but always verify against your motor's full-load current.
Mechanical and environmental robustness
Withstands vibration up to 4 Gn when closed (2 Gn open) and shocks up to 15 Gn closed — typical for machine-mounted contactors near conveyors or compressors. Climatic withstand conforms to IACS and IEC 60947-1 Annex Q Category D, plus TH protective treatment per IEC 60068-2-30 for damp heat. Fire resistance to 850 °C (IEC 60695-2-1) and V1 flame retardance (UL 94).
