Product description

Siemens 6RA2176-4DB0-ZA03 is a SIMOREG K converter for regulated DC drives in the legacy 6RA21 environment. The D460/240 type code identifies the unit as a 460-V-DC device with 240 A output current. Its principal characteristics are the three-phase AC connection, B6C bridge circuit, single-quadrant operation and SIMOREG K control architecture. These ratings matter during replacement because nearby 6RA21 variants cover different voltage and current classes. The complete type number must therefore be compared with the installed converter and the machine documentation. The 240-A class is relevant where the plant requires this precise D460/240 configuration rather than another SIMOREG unit. Electrical compatibility with the existing field supply, control-cabinet layout and connections remains essential on older DC axes. Siemens 6RA2176-4DB0-ZA03 is a type-specific spare position for production equipment that retains classic SIMOREG K DC-drive technology. The combination of the 6RA2176 family, 460-V design and 240-A current class distinguishes it from visually similar converters. The D460/240 allocation also links the B6C configuration to the 6RA21 and 6RA2176 families. Check D460/240 against the installed documentation and retain Siemens 6RA2176-4DB0-ZA03 as the complete procurement identifier. The related 460-V drive class must match the existing DC axis. Before installation, verify the full MLFB, mains supply, field circuit, bridge arrangement and cabinet connections against the existing unit.

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.
