The LC3D320AV7 is a pre-wired star delta starter from the Schneider TeSys D range, built for motor control under AC-3 utilisation category. It switches three power poles, each with 3 normally-open contacts, rated at 32 A with a 400 V AC coil. The IP20 front face protection means the panel-facing side is touch-safe, but the unit is not sealed against washdown — mount inside an enclosure for wet or dusty environments.

Environmental and compliance ratings
Rated for operation from -40 to 70 °C and storage from -60 to 80 °C, with no derating needed up to 3000 m altitude. The housing carries a V1 flame retardance rating per UL 94 and resists fire to 850 °C per IEC 60695-2-1, backed by pollution degree 3 and TH protective treatment per IEC 60068-2-30.
Mechanical and wiring notes
Pre-wired out of the box — no loose contactor and relay to assemble on the panel, which saves DIN-rail space and wiring time on a star delta build.
