The Schneider LC4D18AF7 is a TeSys LC4-D direct-on-line starter combining a contactor and a fuse disconnector in one plate-mount unit. Coil is 110 V AC 50/60 Hz, so the control circuit must supply that voltage; no DC coil option here. Motor power capability varies with line voltage: 10 kW at 500 V, 9 kW at 415/440 V, 7.5 kW at 380–400 V, and 4 kW at 220–230 V. That spread covers most European and Asian industrial supplies. The 173 mm height, 86 mm width, and 98 mm depth footprint fits standard panel layouts on a mounting plate.
Integration notes
Plate-mount design — no DIN rail clip. The contactor and fuse disconnector are integrated internally, so the installer wires the line-side fuses and load-side motor leads directly to the starter terminals. AC-3 duty at 18 A means it is sized for motors in the 7.5–10 kW range depending on supply voltage, typical for pumps, fans, and small conveyors in a control panel.
