The LE4D35R7 is a Schneider Electric TeSys LE enclosed direct-on-line starter, rated for 35 A with a 440 V AC 50/60 Hz control coil. It's built into an IP65 polycarbonate enclosure (330 mm high, 186 mm wide, 175.5 mm deep) with multiple cable entry points — two each of ISO20, ISO25, ISO32, and ISO40 knockouts on both top and bottom faces. This is a standard-duty starter for AC-3 motor loads, meaning it handles the high inrush of squirrel-cage motors during start-up and then switches the running current. The conventional free-air thermal current is 26.5 A, and motor power ratings span 7.5 kW at 220/230 V up to 18.5 kW at 500 V or 660/690 V. It complies with IEC 60947-4-1, the standard for contactors and motor-starters.
Lifecycle reality — this part is obsolete
The LE4D35R7 is marked obsolete by Schneider Electric. If you're planning a new panel or a line rebuild, this is not a part to design in; look at current TeSys offerings for a form-fit-function replacement, but verify the enclosure dimensions and coil voltage against your application.
What you need to order separately
This enclosed starter is not a complete motor-start package out of the box. The device composition requires a thermal overload relay ordered separately, plus a contactor and fuse disconnector. The associated fuse rating is 32 A, 14 x 51 mm aM (motor-protection) fuses. Factor those into your BOM when sourcing this unit.
Environmental limits
This is a standard-environment device — not rated for corrosive atmospheres, high humidity, or extreme cold. If your installation sees sustained temperatures above 40 °C, derating is required, and this part may not be suitable without additional ventilation or a higher-rated enclosure.
