Universal distribution block for aluminum and copper connections

This SIMBLOCK SUB 400 series distribution block is a versatile solution for safe and efficient power distribution in electrical installations. Designed to work with both aluminum and copper wires (Al/Cu), it provides flexibility and reliability in various applications. Its design allows for the connection of solid wires, cable lugs, and flat cables, making it an ideal choice for installers working with diverse types of wiring.

Construction and connection options

The distribution block features a high rated current – up to 400A for copper wires. It accepts a wide range of wire cross-sections, making it easy to adapt to specific installation needs. Connection options include:

• Input:
  • Wire: 1 x (35 - 120 mm²) – ideal for connecting larger power supply wires.
  • Cable lug: 1 x (25 - 95 mm²) – provides a secure connection with cables.
  • Flat cable: 1 x (24x10 mm²) – allows connection of flat cables used in some installations.
• Output:
  • Wire: 2 x (4 - 35 mm²) / 3 x (2.5 - 25 mm²) / 4 x (1.5 - 16 mm²) – great flexibility in selecting cross-sections for branch circuits.
  • Cable lug: 2 x (2.5 - 25 mm²) / 3 x (1.5 - 16 mm²) / 4 x (1.5 - 10 mm²) – allows connection of several circuits with smaller cross-sections.

Safety and application

The SIMBLOCK SUB 400 distribution block is suitable for use in both alternating current (AC) and direct current (DC) circuits, with a rated voltage of up to 1000V AC and 1500V DC. This makes it suitable for a wide range of applications – from industrial installations to photovoltaic systems or electric vehicle chargers. The solid construction guarantees durability and reliability even in harsh operating conditions. It enables safe and organized power distribution in the electrical installation.
