Siemens 6SN1145-1BA01-0DA1 SIMODRIVE 611 55 kW Infeed/regenerative line module
A 55 kW infeed/regenerative line module with internal cooling for a compatible modular drive group.
Product Overview
6SN1145-1BA01-0DA1 is a Siemens SIMODRIVE 611 infeed/regenerative line module rated at 55 kW. The unit combines regenerative energy feedback operation with internal cooling.
This article forms the mains-side energy interface for a compatible 611 drive group. Its exact suffix keeps the power class, contact arrangement and hardware revision distinct from visually similar line modules.
Performance
- 55 kW rated infeed/regenerative module.
- Regenerative energy feedback energy conversion.
- Internal cooling for the documented cabinet installation.
- Verify installed mains contactor arrangement.
- Mains-side support for a compatible SIMODRIVE 611 DC-link group.

FAQ
What rated capacity identifies 6SN1145-1BA01-0DA1?
6SN1145-1BA01-0DA1 is identified by a 55 kW rating in the SIMODRIVE 611 line-module family.
What cooling arrangement belongs to 6SN1145-1BA01-0DA1?
6SN1145-1BA01-0DA1 uses internal cooling; the cabinet airflow and heat-removal path must remain suitable.
Which mains interface must be checked for 6SN1145-1BA01-0DA1?
6SN1145-1BA01-0DA1 requires the verify installed mains contactor arrangement to be verified against the installed wiring.
Can another 55 kW SIMODRIVE module automatically replace 6SN1145-1BA01-0DA1?
No. The complete 6SN1145-1BA01-0DA1 suffix, control version, cooling arrangement, connectors and lifecycle status must all match.
What should be recorded before removing 6SN1145-1BA01-0DA1?
Record DC-link connections, mains contactor wiring, connected power modules, cabinet position and all machine-specific settings associated with 6SN1145-1BA01-0DA1.
How should 6SN1145-1BA01-0DA1 be commissioned after exchange?
After fitting 6SN1145-1BA01-0DA1, verify precharge, DC-link voltage, regenerative operation, protective circuits and machine safety functions before production use.
