It is configured as 3 x 3P (3 NO) and rated for AC-3 utilisation category at 9 A, with a 380 V AC coil. The AC-3 rating of 9 A means this starter is sized for switching three-phase motors up to that current during starting and plugging — the duty that governs contactor life in motor control. The 380 V AC coil matches standard European control voltages; verify your panel's control transformer output before committing the BOM line. IP20 front-face protection (IEC 60529) means the front of the unit is finger-safe, but the terminals are not protected against water ingress — mount inside a rated enclosure. Flame retardance V1 per UL 94 and fire resistance to 850 °C per IEC 60695-2-1 mean the housing will not propagate a flame or sustain combustion — important for panel-level safety compliance. ## Deployment context As a pre-wired star delta starter, the LC3D09AQ7 mounts directly into the panel — typically on a DIN rail or backplate — and connects to the motor contactor group without additional inter-wiring.","metaTitle":"Schneider LC3D09AQ7 TeSys D Star Delta Starter, 9 A, 380 V A","metaDescription":"Schneider LC3D09AQ7 TeSys D star delta starter, 9 A AC-3, 380 V AC coil.
