Siemens 6SL3120-1TE21-8AC0 SINAMICS S120 Single Motor Module 18A Booksize C-Type Drive Module

The Siemens 6SL3120-1TE21-8AC0 is a SINAMICS S120 Single Motor Module in Booksize C-Type frame, converting a 510-720 V DC link into a 3 AC 400 V output rated at 18.0 A (IN), with a base-load current IH of 15.3 A and a peak Imax of 36.0 A. It ships with an integrated DRIVE-CLiQ cable and supports the extended Safety Integrated functions.

Technical Specifications

Selection Notes

The 18.0 A rated current (IN) with a 15.3 A base-load rating (IH) positions this module for single-axis loads around 8.2-9.7 kW, depending on whether the IH or IN basis applies to the duty cycle. Its 36.0 A Imax gives roughly double the rated-current headroom for short-term peaks such as machine start-up. Booksize C-Type frame and internal air cooling mean it shares the DC link and cooling arrangement of other Booksize S120 modules on the same infeed, and its extended Safety Integrated support lets this axis use Safe Torque Off and related safety functions without an external safety relay.

Applications

Fits single-axis SINAMICS S120 booksize configurations — servo or vector-controlled motor axes on machine tools, printing or packaging lines — where the DC link is shared across several motor modules fed from a common Line Module.
