The Schneider Electric LE4D35Q7 is an enclosed direct-on-line (DOL) starter from the TeSys LE range, designed for standard motor starting applications. It integrates a contactor and fuse disconnector in a polycarbonate enclosure rated IP65 and IK07, with a separate thermal overload relay ordered to complete the assembly. The unit is rated for AC-3 utilisation category, meaning it handles the high inrush of squirrel-cage induction motors during starting and breaking. Motor power ratings span 7.5 kW at 220/230 V AC up to 18.5 kW at 500 V or 660/690 V AC, with a 15 kW rating at 380/400 V AC 50/60 Hz — the most common European industrial voltage.
The conventional free air thermal current (Ith) is 26.5 A, which sets the continuous current-carrying capacity of the main power path under open-mounting conditions. The associated fuse rating is 32 A (14 x 51 mm aM) — this is the maximum short-circuit protection the starter is coordinated with, so the upstream fuse must match or the SCCR coordination is lost. Control circuit voltage is 380 V AC 50/60 Hz, not a standard 24 VDC or 230 V control voltage, so the coil supply must be verified against the panel's control transformer tap.
This part is obsolete per the manufacturer's lifecycle status. The IP65 enclosure and AC-3 motor power ratings (15 kW at 400 V) are the key fit checks for any replacement candidate; a direct substitute would need to match the 380 V AC coil voltage, the 26.5 A Ith, and the 32 A aM fuse coordination.
