Product description

The Siemens 1LE1523-3AB43-5AA4-Z is a high-efficiency (IE3) three-phase asynchronous motor, delivering 55 kW (75 HP) at 400V and 750 RPM. It is constructed with a robust cast-iron frame and designed for B3 (foot-mount) installation, ensuring durability and reliability in demanding industrial environments.

This motor is ideal for applications requiring substantial torque at lower speeds, such as heavy-duty pumps, large fans, crushers, and industrial mixers. It serves industries like mining, metallurgy, and heavy manufacturing, where consistent performance is critical. The IE3 efficiency rating contributes to energy savings and reduced operational costs.
