Barrier Blocks

Barrier blocks are 0387250003 terminal blocks that use barriers to divide up the circuits and prevent devices from being connected the wrong way. Barrier blocks come in a variety of sizes with two to six contacts per pole.

Application Field

Barrier blocks are typically used in industrial and commercial applications where multiple circuits are needed. They can be used to divide up the circuits in machines and appliances such as washing machines, air conditioning units and industrial equipment. Additionally, they can be used to divide up the circuits in electrical panels to make them easier to manage.

Working Principle

Barrier blocks use barriers to prevent the flow of current between two conductors or poles. The barriers are inserted between the conductors and act as insulators to prevent any current from flowing between them. This makes them ideal for applications where two circuits need to be separated. Barrier blocks use spring mechanisms to make sure the connections are secure. The spring mechanisms also allow for easier assembly as they secure the connections without the need for any additional steps.

Advantages and Disadvantages

The main advantage of barrier blocks is that they are easy to assemble and provide better protection than other types of blocks. They are also cost-effective and suitable for applications with limited space. On the other hand, barrier blocks are not ideal for applications where the current is very high or where the voltages are very low.
