Definition
A conductor bar is a precision-engineered metallic strip or bar designed to conduct electricity within industrial power connector terminal blocks. It serves as a common busbar that distributes electrical power from a single input source to multiple output terminals, ensuring uniform current distribution and reliable electrical connections in industrial control panels, switchgear, and power distribution systems. These components are critical for maintaining electrical continuity, reducing wiring complexity, and enhancing safety in high-current applications.
Working Principle
The conductor bar operates on the principle of electrical conductivity, where its metallic structure allows electrons to flow with minimal resistance. When connected to a power source, it distributes current evenly across all attached terminals through direct physical contact, leveraging its low electrical resistivity and high thermal conductivity to maintain stable performance under load. It functions as a centralized distribution point, eliminating the need for multiple individual wires to each terminal.
Materials
Typically made from high-conductivity metals such as electrolytic copper (Cu-ETP) or aluminum alloys (e.g., 6061-T6), often plated with tin, silver, or nickel to enhance corrosion resistance and improve electrical contact. Copper offers superior conductivity (≥58 MS/m), while aluminum provides a lighter weight alternative. Insulating materials like PVC or polyamide may coat non-contact areas.
Technical Parameters
  • Length 50mm to 1000mm (customizable)
  • Mounting DIN rail or direct panel mount
  • Conductivity ≥58 MS/m (for copper)
  • Cross-Section 10mm² to 150mm²
  • Current Rating Up to 300A
  • Voltage Rating Up to 1000V AC/DC
  • Temperature Range -40°C to +120°C
Standards
ISO 8092, DIN 46277
