It is designed for AC-3 motor control duty, meaning it handles the high inrush current of squirrel-cage induction motors during starting and stopping — the standard utilisation category for motor switching in industrial panels. Rated 32 A in AC-3, so it directly switches a motor load up to that current. The 440 V AC coil matches standard three-phase line voltages across much of the world; verify your control voltage matches before specifying. ## Mechanical and environmental robustness Rated for vibration at 2 Gn (contacts open) and 4 Gn (contacts closed) over 5 to 300 Hz, plus shock resistance at 15 Gn closed and 8 Gn open — this starter holds its state under the mechanical stress typical of conveyor lines and compressor skids. IP2X front-face protection keeps tools and fingers out of the live terminals. The TH protective treatment per IEC 60068-2-30 means it withstands damp heat cycling, so it is suitable for non-condensing humid environments without additional enclosure sealing. ## Flammability and fire safety These ratings confirm the housing material will not propagate a flame or sustain combustion in a fault scenario — a requirement for panel certification in most industrial and building codes.","metaTitle":"Schneider LC3D32AR7 TeSys D Star Delta Starter, 32 A, 440 V","metaDescription":"Schneider Electric TeSys D LC3D32AR7 star delta starter, 3 x 3P (3 NO), 32 A, 440 V AC coil.
