Product description

Siemens 6SN1145-1BA02-0CA1 is a regulated SIMODRIVE 611 infeed/regenerative feedback module for modular drive systems. The module supplies the shared DC link and can return energy to the line when the axes decelerate. Siemens assigns this version to the 36/47 kW power class and specifies internal heat dissipation plus line-contactor control with a normally closed contact. The documented line voltages of 3 AC 400 V, 415 V and 480 V and the associated DC link voltages of 600/625/680 V are relevant for operation. The SIMODRIVE 611 tables specify 36 kW continuous regenerative power and 70 kW peak regenerative power. Supplementary technical data lists a 60.5 A rated current, 200 mm module width and 15.5 kg weight. Connections X121 for temperature and I²t monitoring and X171 for line and precharging contactor control support unambiguous system assignment. For replacement, the complete MLFB, line connection, power class, DC link, module width, cooling concept and control connections must match the installed machine. A visually similar SIMODRIVE module may have a different infeed rating, regenerative class or heat-dissipation method. Variants with a different line voltage or external heat dissipation also cannot be identified safely from the front view alone. The complete order number prevents incorrect assignment. Siemens 6SN1145-1BA02-0CA1 is therefore especially suitable for targeted maintenance of older machine tools, machining centers and production equipment whose SIMODRIVE-611 system must remain in its original configuration. The exact type number simplifies comparison with the circuit diagram, bill of materials and cabinet layout without claiming blanket interchangeability with neighboring 6SN1145-Varianten. For retrofit projects, line effects, precharging and machine engineering must still be checked separately.

FAQ

Frequently asked questions

Contact us
What does Siemens 6SN1145-1BA02-0CA1 do?

The regulated SIMODRIVE 611 infeed/regenerative feedback module supplies the DC link and can return braking energy from the drive system to the line.

Which regenerative power is documented for 6SN1145-1BA02-0CA1?

The Siemens system data specifies 36 kW continuous regenerative power and 70 kW peak regenerative power for this power class.

Is there a guarantee?

Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.

Please note that the guarantee only applies when the warranty seal is undamaged.

If a defect occurs within 14 calendar days, please contact us in writing. Subject to availability, we will provide a replacement or refund the full purchase price after return.

Further details are provided in the terms and conditions supplied with your quotation.

How quickly do you dispatch and which shipping options are available?

We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.

Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.

We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.

Which payment methods are available?

Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.

As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.

Can we return items if they were ordered incorrectly?

Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.

Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.

Is there a discount when ordering several items?

For larger order quantities or several items of one type, we can offer individual discounts.

Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.

Do you also purchase industrial spare parts?

Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.

The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
