The Schneider LC4D12AV7 is a direct-on-line (DOL) starter from the TeSys LC4-D series, integrating a fuse disconnector and contactor in a single unit for motor starting and protection. It is rated for AC-3 utilisation category, meaning it is designed for starting and stopping squirrel-cage induction motors under load.
Motor power coverage across common line voltages
The LC4D12AV7 covers a range of motor power ratings depending on the supply voltage: 3 kW at 220...230 V AC, 5.5 kW at 380...400 V AC, 5.5 kW at 415 V AC, 5.5 kW at 440 V AC, and 7.5 kW at 500 V AC — all at 50/60 Hz. This voltage-dependent rating is typical for AC-3 duty; the 16 A operational current is the common thread. When specifying a replacement, the motor power at your line voltage is the primary selection criterion.
Mounting and physical integration
The DOL starter mounts to a plate, not a DIN rail. The dimensions are 173 mm height, 86 mm width, and 98 mm depth. When panel-mounting, account for the plate footprint and clearance for the integrated fuse disconnector handle.
