The Siemens 6SL3211-0KB11-2BA0 is a SINAMICS G110 CPM110 AC drive rated 0.12 kW for both constant-torque (CT) and variable-torque (VT) loads, fed from a single-phase 200-240 VAC supply at 47-63 Hz. The built-in Class B EMC filter means it meets conducted emission limits for residential and light industrial environments without an external filter — one less part to panel-mount and wire.
The CT rating of 0.12 kW with 150% overload for 60 seconds is the number that governs motor sizing for pumps, conveyors, and fans that need starting torque or short-term overload capacity. The same 0.12 kW VT rating applies for centrifugal loads where torque follows the square of speed. Ambient temperature range of -10 to +50 °C without the optional BOP (Basic Operator Panel) means this drive runs in a warm cabinet up to 50 °C — but you lose the local keypad and display unless you add the BOP as an accessory.
Dimensions of 150 x 90 x 101 mm (HxWxD) without a heatsink let it fit in a shallow panel, but the lack of an external heatsink means the drive relies on convection within the cabinet; keep clearance above and below for airflow. Single-phase input simplifies wiring for a 230 V shop-floor supply, but the built-in Class B filter adds a small leakage current to ground — verify with your RCD type.
