Product Introduction
The ABB RMU610 / 2VAA008425R1 is not a conventional PLC CPU or I/O module. It is identified as a Repeater Mounting Unit and, more specifically, the mounting base for the redundant cRBX01. The assembly provides the physical mounting/interface arrangement required for the corresponding redundant repeater hardware (the horizontal configuration is part of the product identification).
Treat the RMU610 as a mechanical/system-interface component during asset control. Its dimensions are compact—95.5 × 127 × 127 mm—and its listed net mass is only a few hundred grams, but incorrect identification can still create a cabinet compatibility problem. Match 2VAA008425R1 against the engineering BOM and the installed cRBX01 arrangement before issuing the spare.
The 853710 / 85371091 classification above is a supplier-provided classification, not a universal customs ruling. Another trade-data source has reported shipments of this exact base under 8517790000, demonstrating why the importer should have the broker validate the HS classification for the destination country.

? Global Compliance & Industry Certifications
- CE Mark: Verify whether conformity is declared for the complete ABB equipment/system rather than treating the mounting base as an independently certified product.
- UL/cUL Listed: Verify the exact installed configuration and certification file before making a UL/cUL claim.
- ATEX / IECEx: No evidence was found establishing independent hazardous-area certification for . Do not treat it as an ATEX/IECEx component solely because it may be installed in an industrial facility.
- Marine / DNV: Verify the specific ABB system certification if the equipment is intended for marine or offshore service.
- HS Classification: Supplier databases list 853710 / 85371091, while trade records also show 8517790000 for the same part number. Classification should therefore be reviewed against the actual product function and destination-country tariff schedule.
- Country of Origin: Do not rely on reseller web pages. One supplier reports Switzerland, another Sweden, and another Germany, so the COO must be established from the actual product documentation or manufacturer-origin evidence.
For plant safety, certification must apply to the actual installation configuration and hazardous-area conditions. A generic certification claim attached to a reseller listing is not sufficient for an audit.
Verify specific lot certifications with OEM.
? Long-Term Storage & Asset Preservation Guide
- Keep the dry and protected from contamination. Although it is primarily a mounting/interface component, exposed mating surfaces and connector interfaces can accumulate dust or develop oxidation during prolonged warehouse storage. Retain the original packaging where possible.
- Prevent mechanical deformation. Do not stack heavy equipment directly on the 95.5 × 127 × 127 mm unit. The mounting geometry must remain square so the associated cRBX01 assembly seats correctly (a small mechanical distortion can become a connector-alignment problem).
- Preserve identification. Keep the ABB product label readable and record / 2VAA008425R1 in the asset register. Photograph the label before storage; this prevents an otherwise avoidable part-number dispute years later.
No battery, processor, or firmware-dependent storage procedure is indicated for the mounting base itself.
Physical Installation Prerequisites
- Install the unit in the horizontal orientation specified for the .
- Confirm that the mounting location is intended for the redundant cRBX01 configuration.
- Reserve physical clearance around the 127 mm deep/127 mm high assembly for connector access and service removal.
- Do not impose clearance requirements intended for heat-generating CPUs or power modules on this passive mounting base; its thermal burden is fundamentally different.
- Ensure the cabinet mounting surface is rigid and correctly aligned.
- Verify all associated grounding, connector, and mounting requirements against the ABB system drawing.
- Before commissioning, confirm that the installed cRBX01 and combination matches the approved cabinet BOM.
Buyer’s FAQ
Q: Which HS tariff code should I use for ?
A: A product database lists HS 853710 and customs tariff 85371091, but trade records show the same 2VAA008425R1 under 8517790000. Use the destination country’s tariff rules and obtain broker confirmation before filing the customs entry.
Q: Why are different Country of Origin values appearing online?
A: Because reseller records are inconsistent. Switzerland, Sweden, and Germany have all been reported by different suppliers. None should replace the actual manufacturer’s COO evidence or the applicable Certificate of Origin.
Q: Do I need shipping insurance for a 0.3 kg mounting base?
A: Weight is not the deciding factor. If the replacement cost, production impact, or availability is significant, insure the shipment based on its declared commercial value. Photograph the packaging and part number before dispatch.
Q: Does contain the latest firmware?
A: No standalone firmware should be expected. is identified as a mounting/interface base for the redundant cRBX01, not a programmable CPU or firmware-bearing controller. Any firmware consideration belongs to the associated electronic module.
