Drive specs and deployment context
The Siemens 6SL3211-0KB12-5BB0 is a SINAMICS G110 CPM110 AC drive rated 0.25 kW for both constant-torque (CT) and variable-torque (VT) loads, with a CT overload capability of 150% for 60 seconds. It operates from a single-phase 200-240 VAC supply (+10/-10%) at 47-63 Hz and includes a built-in Class B EMC filter, so no external filter is needed for residential or light industrial environments. The RS485 interface with USS protocol handles drive control and parameterization from a PLC or PC — no fieldbus gateway required for basic setups. Physical dimensions are 150 x 90 x 101 mm (HxWxD), and it ships without a heatsink — panel builders should account for that in thermal design.
The 0.25 kW rating at both CT and VT tells you this drive is sized for a small motor — think a 0.33 HP induction motor on a conveyor, pump, or fan under 1 A full-load current. The 150% overload for 60 seconds gives you headroom for starting torque or short-duration load spikes without tripping. Single-phase input means it connects to a standard wall outlet or control transformer, not a three-phase supply — useful for retrofit or remote equipment where three-phase power isn't available. The built-in Class B filter meets EN 55011 for conducted emissions, so it won't radiate noise back onto the line in a residential or light-commercial panel. IP20 and no heatsink: plan for forced airflow or generous cabinet volume if the drive runs near full load continuously.
