The Schneider Electric LE4D25U7 is a TeSys LE enclosed direct-on-line (DOL) starter, rated 25 A thermal current (Ith) with a 240 V AC 50/60 Hz control coil. It's built for standard motor starting duty (AC-3 utilisation category) and carries motor power ratings from 5.5 kW at 220/230 V up to 15 kW at 500 V — the 11 kW at 380/400 V is the typical pick for a 400 V line. The enclosure is polycarbonate, IP65-rated, with IK07 impact resistance — so it handles washdown environments and light mechanical knocks on the plant floor. Cable entries are pre-punched on top and bottom for ISO20, ISO25, ISO32, and ISO40 glands, giving you flexibility on the incoming supply and motor leads. The device composition is a contactor and fuse disconnector in one box; you order the thermal overload relay separately. The associated fuse rating is 25 A, 10 x 38 mm aM type. Push-button controls are integrated — green start, red stop/reset.
No official Schneider successor order code is on record for this variant.
The AC-3 utilisation category tells you it's rated for starting squirrel-cage motors and switching them off during running, not for high-inrush or plugging duty.
