The TeSys LC4D18AV7 is a direct-on-line (DOL) starter combining a fuse disconnector and a contactor in a single unit, plate-mounted, rated for 18 A operational current in AC-3 utilisation category — the standard duty for squirrel-cage motor starting and stopping under load. Motor power capability varies by supply voltage: 10 kW at 500 V AC, 9 kW at 415 V and 440 V, 7.5 kW at 380–400 V, and 4 kW at 220–230 V — all at 50/60 Hz. The 400 V AC coil means it is wired directly to a 400 V phase-to-phase control circuit; no control transformer needed if the line voltage matches.
No last-time-buy window remains open.
Plate-mounted — designed for bolting directly to a backplate or sub-panel, not DIN rail. Dimensions: 86 mm wide, 173 mm tall, 98 mm deep. The integrated fuse disconnector saves panel space and wiring time compared to a separate fuse holder plus contactor combination, but the plate-mount footprint means it occupies a fixed location — no snap-on repositioning.
