Product description
The ABB ACS550-01-03A3-4 is a wall-mounted general purpose frequency converter for industrial three-phase drives. Its type code identifies the ACS550-01 series, R1 frame size and 380 to 480 V supply range. ABB rates this exact variant at 1.1 kW motor power and 3.3 A output current in normal use. Heavy-duty operation is rated at 0.75 kW and 2.4 A. The 0.75 kW stated in the eBay title therefore corresponds to the documented heavy-duty rating, while 1.1 kW is the normal-use rating. This distinction must be considered when matching the load profile. The three-phase mains input accepts +10 % / -15 % voltage tolerance at 48 to 63 Hz. On the motor side, the converter provides a three-phase output from 0 to supply voltage and an output frequency from 0 to 500 Hz. The standard version has IP21 protection and is intended for protected wall mounting. In frame size R1, it measures 369 mm high including the cable connection box, 125 mm wide and 212 mm deep; weight is 6.5 kg. ABB specifies 40 W heat dissipation and a cooling air requirement of 44 m³/h for thermal planning. A 10-A-gG IEC input fuse is recommended. The ACS550 platform includes Modbus communication over EIA-485 as standard and supports optional plug-in fieldbus modules. Before replacement, compare the complete type number, load profile, motor current, mains voltage, enclosure protection, parameters, fieldbus, mounting area and airflow. Existing terminal assignments and stored settings must also match. The ACS550-01-03A3-4 is intended for targeted maintenance where this exact compact R1 current class is required in an ABB drive application.

Manufacturer / EU responsible person
Is the ABB ACS550-01-03A3-4 rated at 0.75 or 1.1 kW?
ABB specifies 1.1 kW in normal use and 0.75 kW in heavy-duty use. The applicable rating depends on the load profile.
Which installation conditions apply to the R1 unit?
The IP21 wall-mounted version requires a suitable mounting area, unobstructed cooling airflow and a protected installation location; ABB specifies 44 m³/h airflow.
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.
