Siemens 6SL3351-1AE33-8AA2 Single Motor Module – SINAMICS S120 Booksize Series
When a SINAMICS S120 drive axis goes down on the production floor, the entire machine stops. Whether it is a CNC machining center, a high-speed packaging line, or a precision winding system, the loss of a Single Motor Module cascades instantly into unplanned downtime, scrapped batches, and costly maintenance windows. The Siemens 6SL3351-1AE33-8AA2 is the exact replacement component that restores axis control without redesigning your drive cabinet or reconfiguring your control topology.
Within the SINAMICS S120 Booksize family, the 6SL3351-1AE33-8AA2 occupies the mid-range power tier, delivering a continuous output current of 38 A at 3AC 380–480 V. It is engineered for servo and vector applications that demand dynamic torque response and tight speed regulation. As part of Siemens’ globally dominant SINAMICS S120 platform — deployed across automotive, aerospace, printing, and material-handling industries — this module benefits from decades of field validation and a worldwide spare-parts ecosystem.
