What's in the box
The Siemens 6SL3120-1TE23-0SP0 is a SINAMICS VSL spare part kit that bundles two components: one 6SL3120-1TE23-0AC0 drive module and one 6SL3162-2ME02-0AC0 accessory module. This is the kit you order when you need to replace both units together — common for a line-down swap on a SINAMICS VSL axis.
The kit is specified as a spare part for the 6SL3120-1TE23-0AAx base unit. If you're maintaining a SINAMICS VSL drive lineup and the 0AAx variant is in your panel, this kit gives you the drop-in replacement modules without sourcing each piece separately. The 6SL3120-1TE23-0AC0 is the power section; the 6SL3162-2ME02-0AC0 handles the interface or auxiliary functions — together they restore a failed axis to full operation.
