The LC4D18AM7 is a TeSys DOL starter combining a contactor and fuse disconnector in one unit, rated 18 A in AC-3 duty — the motor-switching category that governs starting and stopping of squirrel-cage induction motors. At 18 A AC-3, it directly handles a 7.5 kW motor at 380–400 V AC or 9 kW at 415/440 V AC, and 10 kW at 500 V AC. The 220 V AC coil matches common control-voltage rails in European panel designs. Plate-mount construction (173 mm tall, 86 mm wide, 98 mm deep) means it bolts to a backplate rather than snapping onto DIN rail — factor that into enclosure layout and gland-plate clearance.
Integration note for panel builders
The plate-mount footprint (86 x 173 mm) and 98 mm depth leave room for side-by-side grouping on the backplate, but the fuse-disconnector section adds height compared to a bare contactor — verify clearance to the enclosure door or busbar shroud before laying out the gland plate.
