The LC3D12AM7 is a pre-wired star delta starter from the TeSys D range, built for motor control in AC-3 duty. It carries three power poles, each with 3 NO contacts, rated at 12 A. The coil pulls in on 220 V AC. This is the packaged starter assembly — contactors already interconnected for star-delta transition — so it saves panel wiring time on a standard motor start scheme.
AC-3 category means it is rated for starting squirrel-cage motors and switching them off while running — the 12 A rating governs the motor full-load current it can handle, not the inrush. For a typical 400 V three-phase motor, 12 A AC-3 corresponds roughly to a 5.5 kW load; confirm the motor FLC against the starter rating before committing the BOM line. The IP20 front face means the terminals are finger-safe when mounted in an enclosure, but the starter itself is not sealed against dust or moisture — it needs to live inside a panel or a weatherproof cabinet. Fire resistance to 850 °C per IEC 60695-2-1 and V-0 flame retardance per UL 94 mean the housing materials meet the thermal runaway standards for enclosed power equipment — important for panel certification to IEC 60947 or UL 508A.
