It carries three power poles (3 x 3P, all NO) rated for AC-3 motor control at 9 A, with a 400 V AC coil. AC-3 utilisation category means this starter is sized for starting squirrel-cage motors and disconnecting them while running — the 9 A rating governs the motor FLC it can handle, not a resistive load. The IP20 front face keeps fingers out of the live terminals inside the enclosure.
Rated for pollution degree 3 (industrial environment, conductive pollution), the LC3D09AV7 operates from -40 to 70 °C ambient and stores from -60 to 80 °C. It derates above 3000 m altitude — no derating needed below that. Climatic withstand conforms to IACS and IEC 60947-1 Annex Q category D, with TH protective treatment per IEC 60068-2-30 for humid conditions. Fire resistance at 850 °C (IEC 60695-2-1) and V1 flame retardance (UL 94) mean the housing won't propagate a flame — relevant for panel builders who need to pass a cabinet-level fire test. Vibration withstand: 2 Gn contactor open, 4 Gn closed over 5–300 Hz; shock: 10 Gn open, 15 Gn closed for 11 ms.
Because this is a pre-wired star delta starter, a direct replacement requires matching the 9 A AC-3 rating, 400 V AC coil voltage, and the 3 x 3P contact configuration. A panel OEM or site electrical engineer should verify the mounting footprint and wiring scheme against the existing assembly before committing a substitute.
