The Schneider Electric TeSys LC4D09AB7 is a direct-on-line (DOL) starter combining a contactor and fuse-disconnector in one unit, rated for 9 A in AC-3 utilisation category — the motor-switching duty class that governs inductive loads like pumps, fans, and small conveyors. Motor power capability spans 4 kW at 380...400 V AC, 4 kW at 415 V, 4 kW at 440 V, 2.2 kW at 220...230 V, and 5.5 kW at 660...690 V — so for a 4 kW motor on a 400 V line this starter is correctly sized without oversizing the contactor. Mounting is plate-mount only — no DIN-rail clip, so factor in a backplate or sub-panel for installation.
Lifecycle reality — obsolete, but available
No direct manufacturer successor part number is listed in the lifecycle record, so a like-for-like drop-in replacement from Schneider is not formally designated — the buyer's path is surplus or independent-distributor stock. Condition is typically new-in-box or new-surplus from cancelled projects or overstock.
The 9 A AC-3 rating is the load-bearing figure for motor starting — it governs the contactor's ability to handle the inrush and break the running current under inductive load. For resistive loads (AC-1) the same contactor would carry a higher current, but AC-3 is the number that decides motor fit. Coil voltage is 24 V AC, not DC — if your control system runs 24 VDC, this coil will not hold in. Physical envelope: 86 mm wide, 173 mm tall, 98 mm deep — plate-mount only, so panel layout must allow for screw-fixing rather than snapping onto a DIN rail.
