Product description

Siemens 6SE7021-3TB61-Z is a SIMOVERT MASTERDRIVES Vector Control inverter from the 6SE70 Compact Unit range. The device is an IP20 Inverter Compact Unit for a 510 to 650 V DC supply and provides rated power of 5.5 kW with rated output current of 13.2 A. Siemens 6SE7021-3TB61-Z is therefore a clearly defined spare position below the 17.5-A and 25.5-A SIMOVERT device classes. The documented physical data comprises dimensions of 135 x 425 x 350 mm, a weight of 12.5 kg and assignment to the MASTERDRIVES Vector Control family. This MLFB is particularly relevant when a smaller-current 6SE70 cabinet position must be retained. The 510-to-650-V-DC range suits the documented MASTERDRIVES DC-link environment, while the Compact Unit format supports mechanical matching in the cabinet. The Z suffix remains part of the complete product identifier; it does not justify inventing undocumented internal option codes. With 13.2 A rated output current and 5.5 kW power, the unit occupies a smaller axis or machine-module class on the same 6SE70 platform. Its 135-mm width and IP20 format provide additional identifiers for cabinet replacement. In an installed MASTERDRIVES system, the combined voltage, current class and mechanical format are more useful than the series name alone. Siemens 6SE7021-3TB61-Z is intended for maintenance stock where a compact 5.5-kW Vector Control power unit must be sourced quickly and matched unambiguously.

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.

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.
