The Telemecanique TeSys LC4D09AF7 is a direct-on-line (DOL) starter combining a contactor and a fuse disconnector in one unit, plate-mounted, rated for AC-3 duty at 9 A operational current with a 110 V AC 50/60 Hz coil. The AC-3 rating means it is designed for starting and stopping squirrel-cage motors under load — the 9 A figure governs the motor current it can switch, not the resistive heating current. At 400 V three-phase, it handles motors up to 4 kW; at 230 V, 2.2 kW; at 690 V, 5.5 kW.
This part is marked obsolete by the manufacturer. No official successor order code is recorded in the lifecycle entry.
Physical fit and mounting
Mounts on a plate (not DIN rail), with a footprint of 86 mm wide by 173 mm tall and a depth of 98 mm. The 110 V AC coil draws from a control transformer or separate control circuit — verify the control voltage matches your panel's secondary before specifying.
