The contact configuration is 3 x 3P (3 NO), giving three normally-open power poles per phase for the star and delta contactors plus the line contactor. The coil is 48 V AC, which is common in control circuits fed from a 48 V control transformer. ## Sourcing reality — obsolete part If your application requires a current-production star delta starter in the TeSys D family, a parametric cross-reference to a similar-rated unit with a 48 V AC coil would need to be validated against the existing panel wiring and mounting footprint. ## Environmental and compliance ratings Climatic withstand conforms to IACS and IEC 60947-1 Annex Q category D, and the protective treatment is TH per IEC 60068-2-30 for damp heat. Altitude rating is 3000 m without derating. ## Mechanical robustness for motor starting duty Vibration resistance is 2 Gn with contactor open and 4 Gn with contactor closed across 5–300 Hz. Shock resistance is 10 Gn for 11 ms with contactor open, 15 Gn for 11 ms closed.","metaTitle":"Schneider LC3D12AE7 TeSys D Star Delta Starter, 12 A, 48 V A","metaDescription":"Schneider Electric LC3D12AE7 TeSys D star delta starter, 12 A, 48 V AC coil, 3 x 3P configuration.
