The LE4D12G7 is an enclosed direct-on-line (DOL) starter from the Schneider Electric TeSys LE range, designed for standard motor starting applications. It combines a contactor and a fuse disconnector in a single IP65 polycarbonate enclosure, with a thermal overload relay ordered separately. The unit is rated for AC-3 utilisation category and carries a conventional free air thermal current of 12 A, making it suitable for motors up to 3 kW at 220/230 V AC, 5.5 kW at 380/400 V AC, and 7.5 kW at 500 V AC.
The AC-3 category means the starter is tested for switching squirrel-cage motors: making and breaking currents up to several times rated during starting, without welding the contacts. The 120 V AC control coil matches standard control transformer secondaries in many panels; verify your control voltage matches before wiring. The associated fuse rating is 16 A aM (10 x 38 mm), which provides short-circuit protection for the starter and downstream motor cable. The aM characteristic means the fuse is designed for motor circuits — it allows the high inrush current during starting without nuisance blowing, but clears a fault quickly.
This enclosed DOL starter is intended for standard motor starting applications in industrial and commercial installations — conveyors, pumps, fans, compressors, and small machine tools. The IP65 rating lets it be mounted on the machine or in a wet area without an additional enclosure. The polycarbonate housing is corrosion-resistant and suitable for food-and-bev or chemical environments where stainless steel is not required.
The LE4D12G7 is classified as obsolete by the manufacturer. If you are designing a new panel or have flexibility on the BOM, a current-production TeSys LE or TeSys island starter with the same thermal current and control voltage should be evaluated for fit. Confirm the mounting footprint and cable entry positions before substituting.
The enclosure measures 330 mm high x 186 mm wide x 175.5 mm deep. Cable entries are provided on both top and bottom faces: two each for ISO20, ISO25, ISO32, and ISO40 glands — giving flexibility for different cable diameters. The polycarbonate material is lightweight and can be drilled on site for additional entries if needed, though this voids the IP65 rating unless a proper gland is fitted.
