Eaton B3.0/3-PKZ4 3-Phase Busbar, 128A, 33mm2, Pin-Type

The Eaton B3.0/3-PKZ4 is a high-performance 3-phase pin-type busbar engineered for professional electrical power distribution. Designed specifically for integration with PKZ4 motor protection circuit breakers, this component facilitates a streamlined and reliable connection system within industrial and commercial electrical panels. By utilizing a standardized pin-type interface, it ensures consistent contact quality and structural integrity, which are essential for maintaining stable power flow in demanding electrical environments.

Advantages

This busbar significantly enhances the efficiency of electrical installations by replacing complex individual wiring with a single, robust distribution component. Its design minimizes the risk of loose connections and reduces the overall time required for assembly and maintenance. The high current rating and optimized cross-section provide excellent thermal performance, ensuring that the system remains reliable even under continuous operational loads. Furthermore, the organized layout contributes to a cleaner and more manageable interior of the distribution board, which simplifies future inspections and troubleshooting.

Suitable for

• Industrial motor control centers
• Commercial power distribution boards
• Electrical cabinets requiring PKZ4 circuit breaker integration
• Systems where rapid and reliable 3-phase power distribution is necessary

This busbar may not be suitable for applications involving non-compatible circuit breakers or systems that require a different phase configuration. It is also not intended for use in environments where the physical dimensions of the busbar do not align with the specific spacing of the installed equipment.

Key specifications

• Phase configuration: 3-phase
• Current rating: 128A
• Cross-section: 33mm2
• Connection type: Pin-type
• Compatibility: PKZ4 motor protection circuit breakers

To use the Eaton B3.0/3-PKZ4, ensure that the power supply is completely disconnected from the distribution board. Align the pin-type connectors with the terminals of the PKZ4 motor protection circuit breakers. Once positioned, secure the busbar firmly to ensure full contact across all phases. Verify that all connections are tightened to the manufacturer's specified torque settings before restoring power to the system.

What to consider before purchase

• Verify the compatibility of your circuit breakers with the PKZ4 series
• Ensure the 128A current rating meets your system's load requirements
• Check the physical space available in your distribution board for the busbar length
• Confirm that the pin-type connection matches your existing terminal configuration

For optimal safety and performance, always follow the installation guidelines provided by the manufacturer and ensure that all electrical work is performed by qualified personnel in accordance with local safety regulations.
