The LE4D12FE7 is a Schneider Electric TeSys LE enclosed direct-on-line starter — a self-contained motor start/stop unit in a polycarbonate enclosure, rated for standard industrial environments. It integrates a contactor, push-button controls (green start, red stop/reset), and provisions for a thermal overload relay and fuse disconnector, all pre-wired behind an IP65 door. On a 380/400 VAC supply that translates to 5.5 kW motor power; at 220/230 VAC it covers 3 kW. The control coil is 115 VAC 50/60 Hz — a common control voltage in North American and some European panels.
Sourcing reality — lifecycle and procurement
For a drop-in replacement, the buyer should compare the physical footprint (330 x 186 x 175.5 mm) and the 115 VAC coil voltage against current TeSys island or TeSys GV2 / GV3 enclosed starter ranges, noting that the enclosure cutouts and cable entries (ISO20/25/32/40 top and bottom) may differ.
The polycarbonate enclosure measures 330 mm high, 186 mm wide, 175.5 mm deep — sized for a wall or machine-frame mount, not a DIN rail. Cable entries are pre-punched for ISO20, ISO25, ISO32, and ISO40 glands at both top and bottom, giving flexibility for incoming supply and outgoing motor leads. The unit ships without the thermal overload relay and the fuse disconnector — those are ordered separately and installed in the field. The associated fuse recommendation is 16 A, 10 x 38 mm, aM type (motor-protection characteristic).
