Product description

The ABB 58907961J is the NINT-43 interface assembly for the main-circuit electronics of ACS600 frequency converters. ABB describes the NINT function as issuing control commands and returning measurement signals. Within the control structure, the board sits between the NDCU/NAMC level and the NGDR gate drivers, which amplify the control pulses for the IGBT power stage. The NINT-43 is also listed as a main-circuit interface kit for ACS600 rectifier plate 58918563. The complete combination of ABB code 58907961J and type NINT-43 is therefore essential for maintenance and repair. The offered assembly is a populated circuit board with several plug-in connector strips, a permanently attached ribbon cable and four mechanical mounting points at the corners. The board carries a barcode label with CODE 58907961J and TYPE NINT-43, together with a clearly visible ESD marking. In parallel ACS600 inverter modules, ABB also documents a fibre-optic connection from the NINT to the NPBU PPCC branching unit; current transformers for output-current measurement are connected to the NINT as well. These functions make the board a system-specific component of the internal power electronics. Before installation, the rectifier-plate designation, board revision, connectors, ribbon cable, mounting and installation orientation must therefore be compared in full. ESD-safe handling is particularly important for the exposed electronics. The published weight of approximately 0.26 lb is only a mechanical guide. A precise board comparison reduces the risk of assigning connections or mating connectors to a different NINT version. The NINT-43 is suitable as a targeted spare part when an existing ACS600 converter uses this exact main-circuit interface card. A match based on the ACS600 family alone is insufficient because the range uses different boards and rectifier plates.

FAQ

Frequently asked questions

Contact us
What is the function of the ABB NINT-43?

The NINT-43 is listed as a main-circuit interface board for ACS600 rectifier plate 58918563. It forms part of the frequency converter's internal drive electronics.

Which markings must match during replacement?

The ABB code 58907961J, type designation NINT-43 and assignment to the installed rectifier plate are decisive. The board revision, connectors and ribbon cable should also be compared.

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.
