ABB 3BHE050077R0102 | Net Weight & Export Compliance

Description

• Model & Brand: ABB 3BHE050077R0102 — associated with the UNS0881b-PV2 / GDI PCB assembly designation. Public product references identify it as a replacement for ABB 3BHB006338R0002.
• Physical Dimensions: Approximately 306 × 245 × 40 mm (W × H × D) based on published third-party dimensional data. Confirm against the actual revision before cabinet planning.
• Estimated Net Weight: Approximately 0.29 kg according to published product data.
• Estimated Shipping Weight: Allow approximately 0.6–1.0 kg for the PCB, ESD shielding, cushioning, carton, and documentation. This is a freight-planning estimate, not an OEM packing specification.
• What’s in the Box: PCB assembly/module, ESD protective packaging, cushioning, and applicable documentation. Terminal blocks, mounting hardware, and manuals should not be assumed unless specifically listed on the supplier’s packing list.
• Handling: Keep the board inside its antistatic packaging until installation. Avoid touching exposed PCB traces, connectors, or component leads.

Product Introduction

Architecture Hook

The ABB 3BHE050077R0102 is a board-level assembly intended for integration into ABB industrial power-control architecture rather than standalone field operation. Published references associate the part with the UNS0881b-PV2 GDI designation, and ABB documentation identifies it as the replacement product ID for 3BHB006338R0002.

That distinction matters during replacement. A physically similar PCB is not automatically an electrically compatible substitute. Firmware or hardware revision, connector configuration, and the host drive or excitation-system architecture must all be checked before installation (particularly when maintaining an older installed base). Public technical references associate this part family with ABB power-electronics and drive/excitation applications, but the exact system compatibility should be established from the equipment BOM and OEM documentation.

Core Technical Specifications

ABB 3BHE050077R0102

ABB’s published record for the predecessor 3BHB006338R0002 lists 320 × 230 × 37 mm and 0.266 kg, while identifying 3BHE050077R0102 as the replacement product ID. Do not automatically substitute those predecessor dimensions for the current part during enclosure engineering.

? Global Compliance & Industry Certifications

For international procurement, treat certification status as configuration- and system-dependent rather than assuming that every individual PCB carries every plant-level approval.

• CE Mark: May apply when the board is incorporated into a CE-compliant ABB assembly or system. Verify the applicable Declaration of Conformity.
• UL/cUL: Do not treat the PCB’s industrial use as proof of an individual UL or cUL Listing. Confirm the exact ABB assembly and certification file.
• ATEX/IECEx: Relevant only where the complete installed equipment is intended for hazardous-area service. A PCB part number alone does not establish hazardous-area approval.
• Marine approvals: DNV or other marine approvals must be verified against the complete equipment/system certification. Do not infer marine suitability from the component’s industrial construction.
• Plant safety: Hazardous-area certification is important because the certification covers controlled ignition risk under defined environmental and installation conditions. Using an uncertified substitute can invalidate the equipment’s compliance basis.

Verify specific lot certifications with OEM.

? Long-Term Storage & Asset Preservation Guide

1. Keep the PCB in its original ESD shielding bag. Store it in a dry, temperature-controlled cabinet away from VFD exhausts, transformer heat, and direct sunlight. The exposed connector pins and PCB surfaces should never be left open on a warehouse shelf.
2. Control humidity aggressively. A warehouse target below 60% RH is appropriate for long-term electronic storage; lower humidity is preferable where practical. Add desiccant inside the secondary package when the storage environment is not tightly controlled (especially for multi-year spares).
3. Do not power-cycle a long-stored board merely as a storage test. If the installed system has been dormant for years, follow ABB’s applicable commissioning procedure before energization. Verify revision identity, inspect the PCB for corrosion or contamination, and check the connectors before insertion.

Physical Installation Prerequisites

• Install the board only in the ABB equipment, rack, or power-electronics assembly for which the specific revision is approved.
• Provide sufficient enclosure clearance for the host assembly’s specified airflow path. Do not place wiring bundles directly across ventilation openings or heatsinks.
• The board should remain protected from conductive dust, condensation, oil mist, and uncontrolled cabinet humidity.
• Use the specified mounting hardware and connector arrangement from the applicable ABB cabinet or system manual. Do not improvise DIN-rail mounting unless the host assembly explicitly provides that mechanism.
• Verify cabinet protective earth and bonding before energization. A PCB’s signal reference and the cabinet’s protective-earth system are not interchangeable.
• Inspect retaining clips, card guides, connectors, and mating surfaces before installation. A mechanically incomplete insertion can produce intermittent control faults that resemble an electronic failure.

Buyer’s FAQ

Q: What HS tariff code should be used for international shipment?
A: The part is commonly classified within the HS 8537 family in published commercial data, but different jurisdictions may require a more specific national tariff suffix. One published reference gives 85371092, while another gives 8537101190. Treat these as indicative classifications only and confirm the final code with the customs broker.

Q: Why does the Country of Origin matter if the part is an ABB spare?
A: COO can affect customs duty, preferential tariff eligibility, import documentation, sanctions screening, and origin reporting. Published distributor information identifies Switzerland, but the actual supplied COO certificate or manufacturer documentation should control the shipment declaration.

Q: Should shipping insurance be purchased for one PCB?
A: Yes, particularly for an obsolete or high-value replacement board. The board should be sealed in ESD protection, immobilized with cushioning, and shipped in a rigid carton; insurance should cover the declared commercial value and the applicable transit risks.

Q: Does 3BHE050077R0102 arrive with the latest firmware pre-loaded?
A: Do not assume so. This is a hardware/PCB assembly, and compatibility can depend on hardware revision, firmware, and the host ABB system configuration. Confirm the actual revision and firmware status from the supplier’s photographs, label, test report, or ABB documentation before treating the unit as a direct replacement.
