Product description

Siemens 6SC6520-4AA02 is intended for component-equivalent replacement in legacy NC and SIMODRIVE-650 systems where modernisation is not planned. The unit is identified as a complete SIMODRIVE 650 transistor pulse converter or PWM converter. Service data states 150 kVA rated apparent power and 200 A rated current. It is therefore intended for machines whose power section, cooling path, wiring and surrounding drive components are already matched to this exact unit. In older systems, the series name alone is insufficient because current class, construction and integration into the NC architecture are determined by the complete type number. Before installation, compare Siemens 6SC6520-4AA02 against the rating plate and project documentation, including power requirement, mechanical mounting, cable routing, thermal integration and adjacent modules. Fuses, connection diagrams and diagnostic integration must remain compatible. Cabinet depth, service access, air flow and mechanical fastening require particular attention because physical differences can otherwise necessitate modifications. Lifting and handling must also be planned for this heavy unit. Siemens 6SC6520-4AA02 is a specific spare unit for service and stockholding where this exact SIMODRIVE-650 version is required. Retain Siemens 6SC6520-4AA02 in the maintenance list, verify Siemens 6SC6520-4AA02 against the cabinet documentation and use 6SC6520-4AA02 as the exact order reference. It is available directly from our warehouse in Germany.

Frequently asked questions

Contact us
Is there a warranty?

Yes. We provide a 14-day functional warranty for used items. The component must be functional on arrival, and the warranty applies only while the warranty seal remains undamaged. If a fault occurs within 14 calendar days, please contact us in writing. Depending on availability, we will either provide a replacement or refund the full purchase price after the item has been returned. Further details are set out in the terms and conditions supplied with our quotation.

How quickly do you ship, and which shipping options are available?

We normally dispatch available items immediately and, in many cases, on the same working day. For urgent requirements or machine downtime, we will identify the fastest suitable option and can confirm a specific delivery window on request. Express shipping and collection from our premises are also possible by arrangement. We ship worldwide using reliable parcel and freight carriers; freight shipments may require additional preparation to ensure safe delivery.

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.

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.
