The Siemens 6SL3211-0AB13-7BB0 is a SINAMICS G110 CPM110 AC drive rated 0.37 kW for both constant-torque and variable-torque loads, fed from a single-phase 200-240 VAC supply. It carries a built-in Class B EMC filter, so it meets conducted-emission limits for residential and light-industrial environments without an external filter module — one less part to panel-mount and wire. The drive communicates over RS485 using the USS protocol, which is the standard serial link for Siemens micromaster-class drives. No fieldbus module is built in; if you need PROFIBUS or PROFINET, you step up to the G120 series.
What the ratings mean for fit
The 0.37 kW rating at both CT and VT means the drive is sized for a 0.37 kW motor regardless of load profile — pump, fan, conveyor, or simple speed control. The CT overload is 150% for 60 seconds, which handles short-duration starting torque or load spikes without tripping. For a cement plant environment, that 150% 60s overload buys you a few seconds to clear a choked feed screw before the drive faults out. Ambient temperature range is -10 to +50 °C, but that rating applies without the BOP (Basic Operator Panel) and analog input option modules fitted. If you add those, derate the ambient or provide forced ventilation. The IP20 enclosure means it belongs in a clean, dry cabinet — not on the machine frame where cement dust will settle into the heatsink. Dimensions are 150 x 90 x 116 mm (H x W x D). That's a compact footprint for a 0.37 kW drive — fits a small sub-panel or a crowded DIN-rail section. The built-in Class B filter saves roughly 40-50 mm of DIN rail space compared to an external filter module.
Lifecycle and sourcing reality
The 6SL3211-0AB13-7BB0 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time. If you are filling a production line or a panel build, send the RFQ with quantity and target delivery date.
