Drive selection memo
The Siemens 6SL3211-0KB11-2UA0 is a SINAMICS G110 CPM110 AC drive sized for a 0.12 kW constant-torque (CT) or variable-torque (VT) load on single-phase 200–240 VAC input, 47–63 Hz. The CT-overload capability is 150% for 60 seconds, which covers short-duration starting or load spikes on pumps, fans, or small conveyors. No internal EMC filter is fitted — plan for an external filter if the installation must meet conducted emission limits for residential or light-industrial environments.
Mounting and environment
IP20 protection and no heatsink mean this drive is intended for a clean, ventilated enclosure — not for washdown or dusty floors. Ambient range is -10 to +50 °C; above 40 °C the output current should be derated per the thermal curve in the manual. Dimensions are 150 x 90 x 101 mm (HxWxD), so it fits a standard small panel footprint with room for a DIN-rail mounted filter alongside.
