Product description
The Siemens 6SE6440-2UD21-5AA1 is a MICROMASTER-440 frequency inverter for demanding variable-speed three-phase drives in industrial machinery and plants. The exact FSA version operates from a three-phase 380 to 480 V AC supply at 47 to 63 Hz. Siemens specifies 1.5 kW rated output at constant torque, 5.9 A input current and 4.1 A output current. Overload capability is 150 % for 60 seconds and 200 % for 3 seconds. Vector control, FCC and a linear V/f characteristic are available for motor control. Six digital inputs, three relay outputs, two analog inputs and two analog outputs support flexible integration into the machine control; a PTC/KTY interface is also provided. The device offers IP20 / UL Open Type protection and is intended for installation in a suitable control cabinet. Dimensions are 73 × 173 × 149 mm and net weight is 1.3 kg. The permissible operating temperature ranges from -10 to +50 °C. This version is supplied without an integrated line filter and without an AOP/BOP operator panel. The complete order number is essential for replacement because mains class, power rating, filter configuration and options must match. Before removal, back up parameters, ramps, limits, motor identification and I/O assignment. Also verify the mains supply, motor ratings, braking resistor and installed operator or communication modules. Direction of rotation, setpoint source, enable logic and protection limits must be checked against the machine documentation before recommissioning. Installation and commissioning must be carried out by qualified personnel. The Siemens 6SE6440-2UD21-5AA1 is therefore a clearly identifiable replacement for existing 1.5 kW MICROMASTER-440 applications.

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.
