Product description

Siemens 6SE7021-0EA51 is a SIMOVERT MASTERDRIVES Motion Control converter from the 6SE70 family. The Compact Unit is specified for a 3-phase AC input of 380 to 480 V at 50/60 Hz and has a rated current of 10.2 A. Siemens 6SE7021-0EA51 is therefore an AC-fed MASTERDRIVES device that can serve as a clearly defined replacement assembly in an existing machine. Its IP20 enclosure, Compact Unit format and weight of approximately 13 kg are important characteristics for purchasing, warehousing and maintenance. Unlike DC-link variants, this model is centred on a three-phase AC supply and a Motion Control function within the 6SE70 range. This distinguishes it from other SIMOVERT power units and from accessory modules that may look similar but perform a different task. For spare-parts matching, the full MLFB, input voltage, rated current and mechanical format are the principal criteria. Siemens 6SE7021-0EA51 provides a type-specific procurement option for an installed MASTERDRIVES Motion Control system in the 10.2-A device class. It represents an AC-fed 10.2-A Compact Unit designed for Motion Control applications. These characteristics separate it from similar 6SE70 units and enable maintenance and purchasing teams to match the installed drive with an available spare part without relying on generic drive data or an incomplete series designation.

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.

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.
