Terminal Blocks - Barrier Blocks

0387400112 is a type of terminal block that utilizes a system of barriers within the blocks themselves to maintain insulation between different pairs of adjacent wires in the block. This is an important safety feature, as it reduces the risk of leakage of electrical current or potential between two different pairs of wires carrying current. In addition, barrier blocks can also be used to separate different circuits in the same block.

Application Field

The primary use of barrier blocks is to reduce the risk of short circuits and electrical hazards such as sparks when two different pairs of wires are connected in a terminal block. In many industrial applications, such as in the wiring of control panels, junction boxes, and other electrical systems, the use of barrier blocks helps to improve the overall safety and reliability of the system.

Barrier blocks are also used to provide insulation between different circuits or components within the same terminal block. This can provide greater protection to sensitive electronic components, or where several circuits are running through the same junction box. In addition, barrier blocks can be used to divide multiple circuits into separate zones for system organization, making them much easier to troubleshoot in the event of a failure or malfunction.

Working Principle

The basic principle behind a barrier block is that the internal system of barriers is designed to physically separate the wires running through the block from one another, while still allowing for electrical continuity. This is accomplished through the use of two types of barriers – insulating and conductive. The insulating barriers are made of materials such as plastics and non-metallic polymers, while the conductive barriers are made of materials like metal.

The primary function of the insulating barriers is to prevent electrical current or potential leakage between two different pairs of wires in the same block, while the secondary function is to provide insulation between different circuits or components within the same block. Similarly, the primary function of the conductive barriers is to provide electrical continuity between two different pairs of wires, while the secondary function is to provide electrical insulation between different circuits or components within the same block.

Barrier blocks also have a third type of barrier, which is usually made of metal and acts as an electrical ground. This helps to ensure that all of the circuits in the block are receiving proper grounds.

Overall, barrier blocks are a valuable safety feature in applications where two different pairs of wires are in close proximity. They provide a safe and reliable way to reduce the risk of electrical hazards, while also providing protection against short circuits and providing insulation between different circuits or components within the same terminal block.
