ABB 3BHE055094R0002 GBU72 | Compliance & Traceability

Description

• Manufacturer: ABB
• Model / Type: GBU72
• ABB Part Number: 3BHE055094R0002
• Functional Description: Grid Breaker Unit
• System Family: ABB PCS6000
• Application: Grid-side breaker control/interface within the PCS6000 converter system
• Physical Dimensions: Not reliably established from ABB-published information located for this exact part number. Do not use reseller dimensions for cabinet engineering without the applicable mechanical drawing.
• Estimated Shipping Weight: Not reliably established. Freight planning should use the actual packed unit weight; one aftermarket listing reports approximately 1.16 kg, but this should be treated only as a preliminary logistics estimate.
• What’s in the Box: GBU72 assembly; any associated mounting hardware, interface components, or documentation must be confirmed against the supplied configuration.
• Related Identifiers: 3BHE031197R0001 and 3BHB030310R0001 are listed alongside 3BHE055094R0002 in documentation references for the GBU72. Do not assume they are interchangeable without an ABB compatibility check.

Identification warning: The available documentation identifies GBU72 as a Grid Breaker Unit associated with the ABB PCS6000 product family. Several aftermarket listings incorrectly characterize the same part number as a power supply, brake resistor, rectifier, or generic control module. Those descriptions should not be used for asset classification.

Product Introduction

Architecture hook: GBU72 is part of the electrical infrastructure surrounding an ABB PCS6000 converter rather than a conventional PLC/DCS I/O card. ABB-related documentation identifies 3BHE055094R0002 / as a Grid Breaker Unit, with the PCS6000 documentation covering installation, operation, maintenance, and associated electrical/mechanical drawings.

That distinction matters during replacement. The grid-breaker function is tied directly to converter isolation and power-system protection; the associated ABB documentation states that personnel working with the converter must be appropriately qualified because hazardous voltages can cause electric shock or burns.

Do not classify this asset from the model name alone. The designation, complete ABB part number, hardware revision, and PCS6000 system configuration should all be captured in the maintenance record (particularly when the spare is being held for a legacy converter).

Core Technical Specifications

ABB 3BHE055094R0002 GBU72

ABB-related documentation specifically associates the with the product family and references mechanical drawings, electrical drawings, interface documentation, component data sheets, and upgrade/modification records as part of the converter documentation package.

Do not use the 24 VDC / 72 A specifications appearing in some reseller listings as specifications for this part. Those listings conflict with the Grid Breaker Unit identification and appear to be mixing product classifications.

? Global Compliance & Industry Certifications

For an ABB power-conversion asset, the compliance record should be established from the complete converter configuration and applicable ABB documentation, not from a generic online product listing.

Potential regulatory documentation may include:

• CE Mark — potentially applicable to the complete equipment/configuration placed on the European market.
• UL / cUL — may apply to specific equipment configurations intended for North American installations.
• IEC-based conformity — relevant to the electrical design and protection architecture of the converter.
• ATEX / IECEx — do not assume that itself is certified for hazardous-area installation. The complete equipment arrangement must have the appropriate certification.
• Marine approvals such as DNV — applicable only when the specific installation and hardware configuration has the required marine approval.

The breaker interface is safety-critical because the main circuit breaker provides isolation of the converter’s primary power path. ABB documentation notes that the main circuit breaker must disconnect the main supply without delay following an appropriate open or trip command to prevent personnel hazards and additional equipment damage.

Verify specific lot certifications with OEM.

? Long-Term Storage & Asset Preservation Guide

1. Preserve the original packaging and ESD protection. Keep the sealed in its original protective packaging until installation. Do not place exposed circuit assemblies directly on metal shelving or ordinary packing material.
2. Control humidity and condensation. Maintain a clean, dry indoor storage environment, preferably below approximately 60% RH. Avoid moving a cold spare directly into a warm, humid environment; allow it to reach ambient temperature before opening the protective packaging.
3. Record the complete identity before shelving. Photograph the ABB nameplate, 3BHE055094R0002 marking, designation, hardware revision, and serial/date information. Store the associated documentation with the asset record (this is particularly valuable for legacy equipment).

Do not perform unnecessary powered testing simply because a spare has been in storage. For a grid-breaker assembly, testing should follow the applicable ABB service procedure and qualified-personnel requirements.

Physical Installation Prerequisites

• Installation must follow the ABB mechanical and electrical documentation applicable to the specific converter.
• This is not a generic DIN-rail PLC module. Do not fabricate an alternative mounting arrangement.
• Verify the exact mechanical drawing before allocating cabinet space.
• Maintain the specified clearance for neighboring components, wiring, ventilation, and service access.
• Confirm protective grounding and equipotential bonding according to the installation documentation.
• Verify all associated breaker-control wiring before energization.
• Confirm the correct hardware revision and related configuration before replacement.
• Only qualified personnel should perform installation or maintenance because the associated converter system contains hazardous electrical energy.

One important cabinet distinction: should be treated as part of a high-power converter’s grid-breaker architecture, not as a standalone low-voltage control card. That affects lockout/tagout, access restrictions, inspection procedures, and commissioning documentation.

Buyer’s FAQ

Q: What HS tariff code should be used for 3BHE055094R0002?
A: There is no defensible universal HS code based solely on the name. Classification depends on the actual construction, function, and importing country’s tariff schedule. A customs broker should review the technical description and intended function before the commercial invoice is finalized. Avoid copying an unrelated reseller’s code.

Q: Does the Country of Origin need to match the seller’s country?
A: No. Country of Origin (COO) identifies the applicable manufacturing origin; it is not automatically the seller’s country or the shipping country. Obtain the COO from the physical unit, ABB documentation, or supplier-origin records. For a controlled spare, retain the COO evidence with the commercial invoice and packing documentation.

Q: Should this part be shipped with insurance?
A: Yes, particularly for international freight. Although one supplier reports only about 1.16 kg shipping weight, the functional importance of the within a system can make transit damage operationally significant. Photograph the package before dispatch and retain the packing condition record for any freight claim.

Q: Does include the latest firmware pre-loaded?
A: Do not assume it does. The available documentation identifies 3BHE055094R0002 as a Grid Breaker Unit, not as a conventional programmable CPU with a user-selectable firmware package. If the supplier claims a particular firmware or software revision, request the exact ABB hardware/software compatibility information before accepting the spare.
