Product description

The Heidenhain 646271-01 is a three-phase commutation reactor of the series KDR 140, specifically designed for the Heidenhain UVR 140D converter system. The passive KDR 140 mains reactor reduces harmonic currents and protects both the incoming supply and the downstream converter from transient voltage peaks which occur regularly during operation of machine tools. The commutation reactor reduces feedback effects on the supply network and improves power quality around the machine. The Heidenhain 646271-01 is designed for a 3 × 400 V AC supply and continuously handles a rated current of 3 × 70 A at a system frequency of 50 or 60 Hz. Power dissipation is approx. 340 W; heat is dissipated by natural convection without additional coolant. With its IP 00 protection rating, the device is intended for installation in closed control cabinets, where it is protected from contact and foreign objects by the surrounding housing structure. The KDR 140 weighs approx. 22 kg, which must be considered during control-cabinet planning and installation. The article with the manufacturer ID 646271-01 is an original product of Dr. Johannes Heidenhain GmbH and is supplied as a new item. The KDR 140 is part of the established Heidenhain inverter system and is used with the UVR 140D converter unit in the machine sector for precision axis drives in CNC machining centers and lathes. Directly available from our warehouse in Germany.

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.
