6SN1146-1BB02-0CA2 is a Siemens SIMODRIVE 611 line module with a 36 kW converter rating and external heat removal. It supplies the common DC-link section of a modular SIMODRIVE 611 drive group.

The line module operates with the specified mains-side reactor and filter arrangement, the connected axis modules and the cabinet cooling concept selected for the machine.

• Provides a 36 kW line-infeed position for the modular SIMODRIVE 611 system.
• Uses external heat removal and must remain matched to the cabinet thermal design.
• Supplies the shared DC link used by compatible SIMODRIVE axis power modules.
• Works with the mains-side reactor and filter configuration defined for the drive group.
• Keeps the complete 6SN1146-1BB02-0CA2 suffix visible to distinguish closely related line-module variants.

• Legacy SIMODRIVE 611 drive groups requiring a 36 kW line module.
• Multi-axis machine-tool cabinets with a shared DC link.
• Maintenance replacements that retain existing line reactors and filters.
• Cabinet layouts designed for external heat removal.
• Migration assessments where the existing motor and axis-module inventory must be documented.

• Use the full 6SN1146-1BB02-0CA2 article number rather than selecting only by the 36 kW rating.
• Record the complete drive lineup, DC-link connections, line components and terminal assignments.
• Preserve the external heat removal construction during spare selection or retrofit planning.
• Observe DC-link isolation and discharge procedures before work on the drive group.
• After replacement, test precharge, DC-link stability, axis operation and protective functions.
