The Schneider Electric TeSys LC4D09AE7 is a direct-on-line (DOL) starter combining a fuse disconnector and a contactor in one unit, rated for AC-3 utilisation category at 9 A operational current with a 48 V AC 50/60 Hz coil. It delivers 4 kW motor power at 380...400 V AC, 4 kW at 415 V AC, 4 kW at 440 V AC, 2.2 kW at 220...230 V AC, and 5.5 kW at 660...690 V AC — covering common European and IEC line voltages for three-phase induction motors.
The LC4D09AE7 is classified as obsolete by the manufacturer.
This DOL starter is designed for plate mounting — not DIN-rail snap-on — so panel layout must allocate screw-fixing points and clearance for the 173 mm height, 86 mm width, and 98 mm depth. The integrated fuse disconnector means the unit serves as both the motor-switching and short-circuit protection device in a single footprint, reducing wiring and panel space compared to a separate contactor-plus-fuse arrangement.
