Terminal Blocks - Barrier Blocks

Barrier blocks, also known as terminal blocks, are industrial terminal blocks used to connect electrical circuits. These blocks are designed to ensure a simple and reliable electrical connection. Typically, they are used in main switchboards, PLC Junction Boxes, and for general field wiring serving industrial, commercial, residential, and institutional applications.

Application Fields

Barrier blocks are available in a variety of sizes, types, and colors. Standard voltages vary from 250VAC to 600VAC. These blocks are suitable for a wide variety of applications from motor control, lighting, and home automation to power supplies, data acquisition, and industrial process control. They also provide a safe and efficient means of wiring in hazardous areas by using flame-retardant barriers between the connections.

In addition, barrier blocks are used in test and measurement applications, including circuit design, laboratory, and high-voltage testing. The compact, low-profile design of the blocks make them an ideal solution for tight spaces. They can also be used for connecting multiple wires in a short length of time.

Working Principles

The design of barrier blocks is based on the principles of electrical current flow. That is, low resistance and high voltage. The blocks provide an electrical connection at two points, with all wires, connectors, and terminals connected between them. This removes the need for additional wiring and connectors.

The blocks contain spring clips that hold secure the wires and terminals, providing electrical contact without the need for mechanical tools. The connections are clearly labeled for easy identification. The blocks also feature fuse clips which protect the circuits from overload.

Barrier blocks can be used to create a large network of connected electrical circuits. This makes them ideal for applications in a wide range of industries and environments. They are available in both snap-on and screw-on styles, and the different types come with different capabilities such as cable diameter and color coding.

In addition to their electrical applications, barrier blocks are also used in many industrial applications such as robotics, industrial automation, and communication systems. Because of their small size and weight, they are commonly used in mobile and portable devices.

Conclusion

Barrier blocks, also known as terminal blocks, are industrial terminal blocks used to connect electrical circuits. They provide a reliable electrical connection between two points. They are available in a variety of sizes, voltages, and colors. They are suitable for a wide range of applications in many industries and environments. Their compact size, low-profile design, and fuse clips make them an ideal solution for tight spaces.
