Product Overview and Key Specifications
The Schneider Electric LE3D12B7 is an enclosed star-delta starter from the TeSys LE range, designed for standard motor starting applications. It is rated for 12 A operational current in AC-3 utilisation category, which covers squirrel-cage motor starting and disconnection during running. Motor power capability spans 11 kW at 380/400 V, 415 V, and 440 V AC, and 5.5 kW at 220 V AC, all at 50/60 Hz. The enclosure provides IP65 protection per IEC 60529, suitable for washdown or outdoor installation, with an IK07 impact rating. Compliance is to IEC 60947-4-1 for contactors and motor-starters. The unit measures 348 mm high, 186 mm wide, and 175.5 mm deep, with a polycarbonate enclosure. Cable entries include multiple ISO20, ISO25, ISO32, and ISO40 knockouts on both top and bottom faces for flexible conduit routing. Power and control circuit connections use screw clamp terminals.
Procurement for this part is through independent surplus and broker channels. A buyer holding a BOM line with this order code should submit an RFQ to confirm availability and pricing.
As an enclosed starter, the LE3D12B7 arrives as a self-contained unit with push-button controls (green start, red stop/reset) integrated into the enclosure. It requires a separately ordered thermal overload relay and, for star-delta configuration, the associated contactors and mechanical interlock. The 24 V AC control coil is standard for safety-isolated control circuits; verify the control transformer sizing accounts for inrush.
