The Siemens 6SL3211-0KB12-5BB1 is a SINAMICS G110-CPM110 AC drive rated 0.25 kW constant torque and 0.25 kW variable torque, fed from a 200-240 VAC 1-phase supply at 47-63 Hz. It carries an integrated line filter and communicates over RS-485 using the USS protocol. The IP20 enclosure with a flat heat sink means it is designed for cooling plate installation inside a panel — not for standalone wall-mount or washdown environments. Ambient temperature range is -10 to +50 °C.
What the ratings mean for fit
The 0.25 kW CT rating (150% overload for 60 seconds) is the figure that governs motor sizing — it handles a small pump, fan, or conveyor motor up to that shaft power. The integrated filter saves panel space and meets conducted emission limits for the 200-240 VAC single-phase supply, so no external EMC filter is needed for most installations. The RS-485 USS interface ties into a Siemens PLC or a Modbus-capable controller without an extra communication module.
