Drive selection memo — 0.12 kW, single-phase, cooling-plate mount
The Siemens 6SL3211-0KB11-2UA1 is a SINAMICS G110-CPM110 AC Drive designated as a spare part, sized for a 0.12 kW constant-torque or variable-torque load on a 200-240 V single-phase supply (47-63 Hz). The 150% overload for 60 s (CT rating) means it handles short-duration peak loads — useful for a small conveyor or pump start — without tripping. It is unfiltered, so expect conducted emissions at the line terminals; an external line filter may be needed for EN 61800-3 Category C2 compliance depending on the installation environment. The flat heat sink and IP20 enclosure mean this drive is designed for cooling-plate installation inside a panel — not for standalone wall-mount or washdown areas.
Sourcing and lifecycle — mature, not obsolete
No official successor order code is listed; the G110-CPM110 platform remains the current offering for this power class.
Integration constraints — no BOP, no RS-485, cooling plate only
The drive ships without a Basic Operator Panel (BOP) and without an RS-485 interface — parameterization requires the optional BOP or a PC connection. Mounting is restricted to cooling-plate installation (flat heat sink against a metal panel surface); the ambient temperature range is -10 to +50 °C. Dimensions are 150 x 90 x 101 mm (HxWxD) — fits a standard 200 mm deep enclosure, but plan for the heat-sink cutout in the backplate. Analog input is standard; no fieldbus module is included, so control is via the analog setpoint and digital inputs only.
