What it is and where it fits
The 6SL3211-0KB12-5BA1 is a SINAMICS G110-CPM110 AC drive rated 0.25 kW on both constant-torque and variable-torque curves, fed from a 200-240 V single-phase supply at 47-63 Hz. It ships with an integrated Class B EMC filter, so no external filter is needed for most European domestic or light-industrial line environments. This unit is marked as a spare part — meaning it was originally intended as a service replacement for an existing installation, not a new-design-in part. The drive carries a flat heat sink and is approved only for cooling plate installation; it has no self-ventilation for free-standing panel mount.
Mounting and thermal constraints
Constant-torque overload capability is 150 % for 60 seconds, which covers most conveyor and pump starting profiles without oversizing the drive. There is no BOP (Basic Operator Panel) and no RS-485 interface on this variant, so commissioning requires a PC connection or the optional BOP if parameter access is needed in the field.
Lifecycle and sourcing reality
Because it is a mature spare part, availability through standard distribution can be intermittent. We source it to order against an RFQ through our independent supply network — availability and current pricing are confirmed at quote time, not on a shelf.
