The Schneider LC3D320AM7 is a TeSys D pre-wired star-delta starter designed for three-phase induction motor starting — it reduces inrush by wiring the motor windings in star during start, then transitions to delta for run. The contactor configuration is 3 x 3P (three poles, three normally-open power contacts) rated at 32 A in AC-3 utilisation category, meaning it handles the high break-current of switching motor loads under full load. The coil is 220 V AC.
Where It Goes and Key Ratings
This star-delta starter mounts in a control panel — the pre-wired assembly simplifies installation compared to building the circuit from separate contactors and timers. The front face carries IP2X protection, so finger-safe against accidental contact inside a closed panel. Ambient operation spans -40 to 70 °C at rated coil voltage, and it derates at altitudes above 3000 m. The housing meets 850 °C glow-wire test (IEC 60695-2-1) and UL 94 V1 flame retardance.
