Product description
The SEW-Eurodrive 31C370-503-4-07 belongs to the MOVITRAC 31C frequency inverter range and is intended for powerful three-phase drives in industrial machines and systems. Its complete type code and additional identification number 826421X enable an unambiguous comparison with the installed unit. For power size 31C370, SEW-Eurodrive documents input voltages of 3 × 380, 400, 415, 460, 480 or 500 V AC at 50 to 60 Hz. Rated input current at 400 V is 69 A. The output stage is rated at 52 kVA, 75 A rated output current and 93 A continuous output current for the 125-percent design. Recommended motor power is 37 kW for constant loads and 45 kW for variable-torque loads or constant loads without overload. The internal current limit can be adjusted between 20 and 150 percent. Output frequency and PWM frequency are configurable, allowing the unit to be integrated into established MOVITRAC-31C drive concepts. Size 4 uses forced cooling and, according to the manual, requires an air flow of 230 m³/h plus at least 100 mm clearance above and below. The documented power loss of 1,200 W must be considered when designing cabinet ventilation. Before replacement, compare the -07 type suffix, identification number, installed option cards, supply and motor data, braking resistor, terminal assignment, control mode and parameter set with the existing system. The offered item is new in original packaging; price, scope of supply and images refer to the specific REHA-Components offer. A backed-up parameter set and professional commissioning by qualified personnel are required for controlled replacement.

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.
