Product description

The Siemens 4EP3800-2US00 is a three-phase line reactor for frequency converters and DC converters. Installed in the line supply, it reduces conducted line feedback generated by power-electronic loads. Siemens specifies an operating voltage range of 400 to 480 V AC at 50–60 Hz. Rated current is 45 A and the documented maximum current is 50 A. With a rated inductance of 0.282 mH and a relative inductive voltage drop of 2 %, the reactor is designed for a clearly defined current and voltage class. Power loss is divided into 54 W winding losses and 19.2 W core losses. These values are important for control-cabinet ventilation and the rated ambient temperature of 40 °C. The open IP00 design uses flat terminals for the main circuit and belongs to insulation class B. With dimensions of approximately 178 × 153 × 120 mm and a net weight of 5,281 kg, the reactor requires a load-bearing mounting surface with adequate air and creepage clearances. The design complies with EN 61558-2-20 and is listed by Siemens as a UL/CSA-recognized reactor. For a safe replacement, the complete Siemens order number 4EP3800-2US00, number of phases, line voltage, frequency, current class, inductance and terminal geometry must match. Fuses, conductor cross-sections, converter rating, mounting position and cooling clearance must also be compared with the system documentation. A similar-looking reactor with a different current rating or voltage drop can alter line and converter behavior. The unit is therefore suitable for targeted maintenance of established Siemens drive cabinets designed for this exact 45-A and 480-V class. Its unambiguous catalog data supports purchasing and precise assignment.

FAQ

Frequently asked questions

Contact us
What electrical ratings does the Siemens 4EP3800-2US00 have?

The documented ratings are 400–480 V AC, 50–60 Hz, 45 A rated current, 50 A maximum current, 0.282 mH rated inductance and 2 % relative inductive voltage drop.

What must be considered when installing the Siemens 4EP3800-2US00?

The open IP00 reactor requires matching flat terminals, adequate air and creepage clearances, load-bearing mounting and cooling for 54 W winding losses plus 19.2 W core losses.

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.
