The TeSys LC4D09AU7 is a direct-on-line (DOL) starter combining a contactor and fuse disconnector in one unit, rated for AC-3 utilisation category — the standard duty for squirrel-cage motor starting and stopping under load. Its rated operational current is 9 A at 240 V AC 50/60 Hz, and it delivers motor power up to 4 kW at 380–440 V AC and 2.2 kW at 220–230 V AC. The coil is wound for 240 V AC supply — verify that the control voltage matches your panel's auxiliary circuit before specifying.
The LC4D09AU7 is classified as obsolete by the manufacturer.
The unit mounts to a plate (not DIN rail), with dimensions 173 mm high, 86 mm wide, and 98 mm deep — factor this footprint into your panel layout if replacing a DIN-rail mounted starter.
