The Schneider LC3D32AM7 is a TeSys D star delta starter, pre-wired for reduced-voltage starting of three-phase induction motors. It switches motor loads under AC-3 duty, rated at 32 A, with a 220 V AC coil. The contact arrangement is 3 x 3P (3 NO), meaning it opens and closes three power poles per phase for the star and delta contactors. The IP20 front face protection means it is safe from finger contact but not sealed against moisture — it belongs inside a control cabinet, not on a washdown line. It operates across -40 to 70 °C at rated coil voltage and can be stored from -60 to 80 °C, which covers most plant-floor conditions without derating up to 3000 m altitude.
The AC-3 utilisation category rating of 32 A is the key selection parameter — it tells you the starter can switch a three-phase squirrel-cage motor up to that current during starting and plugging. Do not confuse this with an AC-1 resistive rating; for motor loads, AC-3 is the governing figure. The 220 V AC coil voltage is fixed — verify your control circuit matches. The pre-wired presentation means the internal star-delta interconnections are factory-assembled, reducing panel wiring time but also meaning the contactor set is not field-configurable for other topologies. Flame retardance V1 per UL 94 and fire resistance to 850 °C per IEC 60695-2-1 mean the housing materials meet the self-extinguishing and glow-wire standards required for panel-mounted equipment in most industrial and commercial installations.
