The Schneider LC4D32AE7 is a TeSys LC4-D direct-on-line starter combining a fuse disconnector and contactor in one plate-mounted unit. Its 32 A rated operational current in AC-3 duty means it switches three-phase induction motors up to 15 kW on a 400 V supply — the rating that governs real motor load fit, not the 48 V AC coil voltage which is the control circuit. The coil pulls in at 48 V AC; if your panel runs a different control voltage, this is the variant you need.
Mounts to a plate — not a DIN rail — so factor in the 164 mm width, 124 mm height, and 98 mm depth when laying out the panel. The plate-mount footprint is standard for TeSys LC4-D starters; verify the cut-out and clearance for the fuse-switch handle swing.
