Drive selection memo
The Siemens 6SL3211-0KB15-5BB1 is a SINAMICS G110-CPM110 AC drive sized for a 0.55 kW motor on a 200-240 V single-phase supply, with an integrated Class B EMC filter built in — no external filter needed for most domestic or light-industrial line conditions. Constant-torque and variable-torque ratings both land at 0.55 kW; the CT overload capability is 150% for 60 seconds, which handles short-duration load spikes on conveyors or small pumps without tripping. Communication is via RS-485 using the USS protocol — no PROFIBUS or PROFINET onboard, so keep that in mind if the upstream controller expects a fieldbus gateway. The flat heat-sink design means this drive is intended for cooling-plate mounting, not free-standing panel air; the IP20 enclosure suits a clean, dry cabinet environment.
Sourcing and lifecycle
It is sourced and quoted to order against an RFQ through independent distribution; current pricing and availability are confirmed at quote time.
Mounting and wiring
Dimensions are 150 x 90 x 101 mm (HxWxD) with the flat heat sink; the IP20 form factor mounts to a cooling plate, not a DIN rail — plan for thermal interface material and a machined panel surface for heat transfer. No analog input and no BOP (Basic Operator Panel) are included, so parameterization requires the USS interface via RS-485 or the optional PC connection kit. Ambient temperature range is -10 to +50 °C; derate above 40 °C per the thermal curve in the manual.
