Distribution Blocks

The primary function of a distribution block is to supply power more efficiently to a series of devices. The secondary function is to isolate short circuit incidents to prevent complete shutdown from occurring. Distribution blocks can handle a range of frequencies and currents. Using distribution blocks requires only one large wire on the input side to link each connected device back to the power source. This eliminates the need for separate wiring of each device. 


What are distribution blocks used for?

Distribution blocks are used in various industries:

  • Heating/cooling for operating heaters, cooling systems and ventilation equipment.
  • Power distribution control in the form of voltage transformers, uninterrupted power supply units and distribution cabinets. 
  • Solar, wind and turbine as the power supply to distribute energy.
  • Electrical vehicles for charging stations.
  • Electronic automation, including elevators, lifting equipment and conveyor systems.

Types of distribution blocks

The two main types of distribution block are:

  • Bussed (enclosed) blocks, which allow for a larger input cable to be split out into smaller cables for branch circuits.
  • Independent blocks, which enable multiple individual circuits to be routed to a single location as they are not connected to each other.
