ABB 3BSE004258R1 SX554

The ABB 3BSE004258R1 SX554 is a DC distribution unit designed for ABB Advant Master / Advant OCS industrial automation control systems. It is mainly used in controller cabinets and power supply assemblies to distribute and manage 60 VDC power supply circuits for reliable operation of ABB DCS control equipment.

As part of ABB Advant Controller power supply configurations, the SX554 is typically integrated with ABB power supply modules such as SA167, SA168, SX540, and related cabinet power assemblies to provide stable DC power distribution.

Product Parameters

Core Functions

• DC Power Distribution

  The SX554 distributes DC power from ABB power supply units to different sections of the control system cabinet.

• Power Supply Integration

  It works together with ABB SA-series power supply units and SX540 power switching/distribution components in Advant Controller configurations.

• System Reliability Improvement

  By providing organized power routing and distribution, the module helps improve cabinet power management and reduces wiring complexity.

• Industrial Control Support

  It is suitable for continuous-operation environments such as power plants, process industries, and large automation installations.

Design Features

• High-current DC distribution capability

  Supports up to 30 A at 60 VDC, suitable for ABB controller cabinet power requirements.

• Compact cabinet installation

  Designed for integration inside ABB Advant system cabinets, allowing efficient use of cabinet space.

• Industrial-grade construction

  Built for long-term operation in industrial automation environments with requirements for high availability.

• Compatibility with legacy ABB systems

  Commonly found in ABB Advant Controller 410 / 450 and related Advant OCS installations.

Hardware Composition

The ABB SX554 typically forms part of a complete power supply assembly including:

• SX554 DC Distribution Unit
• SX540 Power Switch and Distribution Unit
• SA167 / SA168 Power Supply Units
• Cabinet mounting accessories and cable assemblies

For example, ABB power supply kits list 3BSE004258R1 SX554 Distribution Unit DC60V 30A as a component together with SA167 or SA168 power supply modules.

Typical Applications

• ABB Advant Controller 410 (AC410) systems
• ABB Advant Controller 450 (AC450) systems
• ABB Advant OCS distributed control systems
• Industrial power and process automation plants
• Legacy DCS maintenance and spare-part replacement projects

Typical industries include:

• Power generation
• Oil & gas
• Chemical processing
• Paper manufacturing
• Water treatment
• Heavy industrial automation

Maintenance Considerations

• Verify the complete part number (3BSE004258R1) before replacement.
• Check DC input/output wiring configuration before installation.
• Inspect terminal connections for oxidation or looseness.
• Confirm compatibility with existing SA-series power supply modules.
• For discontinued systems, keep tested spare units available to reduce downtime risks.

Overall Evaluation

The ABB SX554 (3BSE004258R1) is a legacy but important DC power distribution component within ABB Advant OCS control systems. Although it is no longer a mainstream new-production item, it remains valuable for maintaining existing ABB Advant Controller installations where system upgrades are not immediately planned.
