Siemens 6SN1145-1BA02-0CA1 SIMODRIVE 611 36/47 kW Infeed/regenerative feedback module
A 36/47 kW infeed/regenerative feedback module with internal heat dissipation for a compatible modular drive group.
Product Overview
6SN1145-1BA02-0CA1 is a Siemens SIMODRIVE 611 infeed/regenerative feedback module rated at 36/47 kW. The unit combines closed-loop regulated operation with internal heat dissipation.
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
- 36/47 kW rated infeed/regenerative module.
- Closed-loop regulated energy conversion.
- Internal heat dissipation for the documented cabinet installation.
- Mains protection with normally closed contact.
- Mains-side support for a compatible SIMODRIVE 611 DC-link group.

FAQ
Which successor is documented for 6SN1145-1BA02-0CA1?
6SN1145-1BA02-0CA1 is superseded by 6SN1145-1BA02-0CA2; compatibility still requires an installed-system review.
What cooling arrangement belongs to 6SN1145-1BA02-0CA1?
6SN1145-1BA02-0CA1 uses internal heat dissipation; the cabinet airflow and heat-removal path must remain suitable.
Which mains interface must be checked for 6SN1145-1BA02-0CA1?
6SN1145-1BA02-0CA1 requires the mains protection with normally closed contact to be verified against the installed wiring.
Can another 36/47 kW SIMODRIVE module automatically replace 6SN1145-1BA02-0CA1?
No. The complete 6SN1145-1BA02-0CA1 suffix, control version, cooling arrangement, connectors and lifecycle status must all match.
What should be recorded before removing 6SN1145-1BA02-0CA1?
Record DC-link connections, mains contactor wiring, connected power modules, cabinet position and all machine-specific settings associated with 6SN1145-1BA02-0CA1.
How should 6SN1145-1BA02-0CA1 be commissioned after exchange?
After fitting 6SN1145-1BA02-0CA1, verify precharge, DC-link voltage, regenerative operation, protective circuits and machine safety functions before production use.
