Product description
The Siemens 6RA-2425-6DS22-0 is a microprocessor-controlled SIMOREG K converter for variable-speed DC drives. Siemens specifies the exact version as a single-quadrant drive with a fully controlled three-phase B6C bridge circuit. The D485/60 Mre-GeE6S22 device designation represents 485 V rated DC voltage and 60 A rated DC current. With a three-phase 400 V armature supply, the unit provides a rated power of 29 kW. The permitted armature supply range is +15 to −20 percent, while the mains frequency is adapted automatically between 45 and 65 Hz. A separate 2 AC 400 V electronics supply and a controllable field rectifier belong to the documented configuration. The manual specifies up to 325 V DC and 10 A for the field circuit. The self-cooled unit is designed for ambient temperatures from 0 to 45 °C, has IP00 protection and weighs approximately 14 kg. Documented power loss at rated DC current is about 230 W. Maximum overload capacity is 1.5 times the rated DC current. The complete 6RA-2425-6DS22-0 order number is essential for replacement procurement; similarly designated SIMOREG units with a different current class, mains voltage or four-quadrant circuit are not automatically interchangeable. Before installation, compare the nameplate, mains and armature voltage, rated current, motor field, terminal assignment, setpoint and feedback signals, parameter set, cooling path and upstream branch fuse. The Siemens manual assigns a 3NE8020 80-A branch fuse to this version. Parameter backups and circuit diagrams should be secured before replacement. The bound eBay source record lists the offered device as used. It is suitable as a specific replacement or stocked spare for an existing SIMOREG K system with exactly the same D485/60 configuration. Universal interchangeability or a completed functional test is not claimed.

What are the ratings of the Siemens 6RA-2425-6DS22-0?
The exact D485/60 version operates from 3 AC 400 V and provides 485 V DC at 60 A rated DC current. The documented rated power is 29 kW.
What must be checked when replacing a SIMOREG K 6RA24?
Compare the complete order number, single-quadrant B6C circuit, mains and armature voltage, rated current, field circuit, terminal assignment, feedback, parameter set, cooling path and the 80-A branch fuse.
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.
