Power distribution blocks

Product Overview

Leipole power distribution blocks always provide the best current distribution solutions with most efficiency and safety for electrical systems, support 1-input multi-output design, and 3 pole power distribution which cover 16-185mm² cable specifications, comply with CE and IEC 60947-7 standards, and are suitable for industrial automation, renewable energy and rail transportation.

Key Advantages

Installation Advantages

  • Ease for Wiring: The connections between main circuit breakers (MCBs) and multiple downstream circuits will become more organized and easier with this simplify of the installation process and reduces labor time.
  • Safety Enhancement: The enclosed design with insulated barriers between terminals helps prevent accidental contact with live parts, reducing shock hazards during installation and maintenance.
  • Neat Organization: By centralizing multiple connections at a single point, they create a more organized panel layout that’s easier to troubleshoot and maintain.

Technical Benefits

  • Multiple Output Options: As you noted, the multiple output terminals give engineers flexibility in system design, allowing for various circuit configurations from a single power source.
  • Current Distribution: They efficiently distribute current from a single large conductor to multiple smaller conductors while maintaining proper ampacity ratings.
  • Space Optimization: Terminal power distribution block often require less space than equivalent terminal strip arrangements, making them ideal for compact electrical panels.
  • Reduced Voltage Drop: By providing direct, low-resistance connections, they help minimize voltage drop compared to daisy-chained wiring methods.

Design Flexibility

  • Scalability: Many wire distribution block are modular and can be expanded as system requirements grow.
  • Ampacity Range: Available in various sizes to handle different current ratings, from small control circuits to large power distribution applications.
  • Material Options: Typically available in copper or aluminum to match specific application requirements and budget constraints.
