Distribution block for installation wires and cables - Onninen wholesaler

Distribution blocks are invaluable elements of medium and more advanced facility switchboards, enabling efficient distribution of power between different power supply circuits. If you are looking for a compact and efficient distribution block, check out the offer of the Onninen wholesaler. You will find products from the best manufacturers of modular equipment and connection equipment - Simblock, Pokój or Eriflex.

What are distribution blocks?

A distribution block (also known as a connection or distribution block) is a device from the group of electrotechnical accessories, which is used in electrical switchboards (distribution cabinets). The main task of the block is to precisely and safely connect different wires to each other - powered from a single source. Thanks to this, the electrical installation is properly prepared for work, and its operation does not cause users any technical problems.

By using a distribution block, you can connect many types of wires with different cross-sections – copper, aluminium, stranded, solid, etc. Connection blocks also allow you to separate power circuits in the installation, as well as separate neutral, protective and phase terminals.

Distribution Block – What Types of Devices Are There?

There are 3 main types of distribution blocks: modular, pass-through and compact. Modular distribution blocks (multi-pole blocks) are accessories installed on DIN rails, allowing the distribution of electrical power to different circuits. Pass-through blocks, on the other hand, allow for the safe connection of aluminum or copper cables, while compact (or single-pole) models connect wires of different diameters.

The distribution block can be available with 1, 2 or 4 copper strips (poles) on which the supply and drain wires are mounted. The wires can be thicker or thinner (with different diameters). The blocks allow, among other things, the connection of a supply wire with a larger cross-section; then the power can be distributed to the drain wires with smaller cross-sections.

How to choose the right distribution block?

When choosing the right distribution block, the most important technical parameters should be analyzed, including the rated current (expressed in amps), the cross-section of the connected wires, and the material of the conductors. The available number of branched poles, inputs and outputs from each pole, as well as the housing color (gray, blue, yellow-green), which allows for visual separation of the phase, neutral, and protective terminals, are also important.
